2D, 2.5D, and 3D X-Ray Inspection – What’s a “D”


The use of x-ray inspection in the electronics industry has gained wide adoption in the past 20 years, driven mainly by the development and use of bottom terminated components (BTC). The use of ball grid arrays (BGA), for example, allowed the development of standards and guidelines that dictate the maximum void size in each ball. In consequence, x-ray machine manufacturers developed solutions that address these requirements to became an integral part of the quality assurance function of modern electronic manufacturers.

However, as new x-ray technologies are introduced – from new algorithms to new hardware – users are faced with a growing range of options to choose from. Users need a solid technical background to understand these options to make an educated decision when acquiring x-ray inspection capabilities. Unfortunately, x-ray companies are not always clear about the pros and cons of each option. As a result, users end up buying too much or too little capabilities. In either situation, the user is left without the right x-ray inspection solution.

The goal of this presentation is to give the audience the tools needed to avoid making mistakes when acquiring x-ray inspection capabilities. We will set the record straight and clearly define critical concepts in x-ray inspection. The different x-ray modalities, 2D, 2.5D, and 3D x-ray inspection will be explained in details at the user level – no math involved. Most importantly, this presentation will cover when each modality must be utilized for a successful quality assurance program. A rich set of images and videos will be used to illustrate the advantages and disadvantages of each x-ray inspection modality.

This was a great opportunity to show off the capabilities of our new tomography system, the TruView Fusion CT. Check it out as we took the 3D x-ray inspection of an Apple AirPod!

The All New TruView Cube


We’re excited to share with you the new generation of TruView Cube! What’s new? Well, let’s start by the major upgrade – the x-ray sensor. The new TruView Cube is now equipped with a high resolution image intensifier – a sensor that produces incredible images. Not only that, the 4″ field of view gives you enough coverage to image a large portion of the your sample. We also added a 10″ HD monitor mounted right on top of the door to mirror the image you get from the 24″ HD monitor. That means you can use the TruView Cube with or without the large monitor, allowing for a very small operating footprint – the smallest in the market! Perfect for your lab where every inch matters.

Enough said, give us a call today to learn more about the new TruView Cube!

New MacBook Pro Teardown


It’s no secret I’ve been using MacBook Pros as my primary computer for over a decade now. I must admit that in the past couple of years I’ve found myself looking jealously at my colleagues who brag about their Surface Pros. The Surface Pro 4 is an amazing machine, one I’ve considered as my next laptop. However, when I think about all the apps I’d have to give up… well, I’m back to the MacBook Pro. Needless to say the launch of the new line of MacBook Pros last week was very exciting news – perhaps the excuse I need to upgrade my 2013 machine!
We received our 13″ MacBook Pro this morning, and the first stop was inside TruView Prime S with a 17″x17″ flat panel. We also took a few photos showing the 2013 MacBook Pro against its successor. For a more detailed teardown please visit our friends at ifixit and let us know what you think!

Industry Intelligence from Teardowns of IoT and Wearables

by Bill Cardoso in Creative Electron Comments: 0

This is a paper we’re presenting at the upcoming SMTA International in Chicago, reproduced here so you can take a read prior to our presentation. Comments welcome!

ABSTRACT
The impulse to break a new gadget to “see what’s inside” is often the first sign someone will become an engineer. However, modern teardowns go far beyond pure curiosity: they provide us critical insights into the nature and construction of these devices. In this paper we will cover the teardown of several smartphone and wearable devices to understand how the SMT industry has changed. These findings will also help us forecast where we are going as a community by discussing miniaturization and packaging, automation and labor force location, device features, and other important topics. These are key issues we need to address to keep U.S. SMT manufacturing relevant.

INTRODUCTION
Figure 1 shows the x-ray of all iPhones in history. This is an important snapshot of the history of SMT assembly for the past 9 years since the iPhone introduction in 2007. The major industry trends can be visualized in this single image: electronics are getting smaller, batteries are getting bigger, and the real estate allocated to the PCB is shrinking. Larger displays with higher resolution require more power. Thinner devices have become a requirement, which in the iPhone 4 led Apple to place the battery on the side of the PCB instead of on top of the PCB. In this paper we will discuss some of the market and technology forces behind these trends.

Apple iPhones from 2007 to 2016

Figure 1. X-ray images of all iPhones since its launch in 2007 to the iPhone 7 launched in September of 2016

WHY TEARDOWN?
We have been tearing down devices for several years now with the pure intent to discover how the devices around us work. However, we found that this process of finding how devices are built can give us incredible insights on how the major companies that make them operate.
This ‘under the cover’ knowledge can provide insights into design information, how the product works, innovative design features and even supply chain relationships. Teardowns may also include an in-depth estimate of the bill of materials (BOM).

Supply Chain Exposure
Once a complete teardown is completed, we can determine the exact BOM for the device. This BOM can be used to determine component selection and supplier relationships. It can also, from generation to generation of these devices, help us determine which of these relationships are flourishing and which are floundering.
This data also assists companies to determine the cost breakdown of different devices, as seen in Figure 2 [3].

Cost drivers for wearables

Figure 2. Wearable teardown landscape showing how different manufacturers are deploying resources in different devices. The top cost driver across platforms continues to be the displays, followed by processors, enclosures, and memory

Market Intelligence
The knowledge that a supplier was picked up as a supplier for a mainstream product can have an incredible positive impact on a supplier’s stock price. Similarly, being dropped from the BOM of an iPhone or Galaxy can negatively impact share value.
One recent example happened the day the new iPhone 7 went on sale worldwide. The first teardowns of these devices happened in Tokyo and Sydney, several hours ahead of the Friday launch date in the USA. The public release that a component by Lattice Semiconductor was present in the iPhone 7 caused shares of the Portland company to climb nearly 14 percent. That happened on Thursday on indications the Portland company has signed up Apple as a major client.

Reverse Engineering
Product managers, competitive intelligence professionals, and engineering leads for semiconductor and component suppliers use our product teardowns to identify [3]:
• What socket opportunities would best suit their products?
• What component integration opportunities are available?
• Which techniques their competitors are using for integrated circuit (IC) packaging?
• What their competition is doing that could be an external threat?
Product managers, procurement professionals, and competitive intelligence analysts in device original equipment manufacturers (OEMs) value product teardown reports for critical insights into:
• Who are the emerging electronic component suppliers?
• What are the best approaches to reducing bill of materials (BOM) and manufacturing costs?
• What emerging technologies are being developed in complementary devices that may be integrated?
• What are the best design, sourcing and manufacturing strategies to compete in the emerging low cost environment?
• What are the competitive strengths of new international market entrants?

THE END OF AN ERA
The 3.5mm audio jack is gone. At the recent announcement of the new iPhone 7 and 7 Plus, when Apple executives revealed the end of the audio jack, “courage” was given as a motivation to remove this traditional interface from their new flock of iPhones.
A reasonable observer may also conclude that Apple’s recent acquisition of Beats (a leading headphone maker) also played an important role since iPhone 7 users will likely be in the market for new wireless headphones.
Therefore, we emphasize the importance to pay attention to the merger and acquisitions activities of the major players in the SMT market. These moves might not make immediate sense, but in the case of Apple’s acquisition of Beats, it was a very early signal of a major shift in the way devices are built.
Figure 3 shows an x-ray image of the now defunct audio jack in an iPhone 6S. Figure 4 shows an x-ray image on the same corner of the iPhone 7. The large rectangular object in this x-ray image is the improved Taptic Engine in the iPhone 7 and 7 Plus. This device is responsible for the haptic or kinesthetic communication that recreates the sense of touch by applying forces that react to the user’s touch. Thus we can say that very soon mechanical buttons will be a thing of the past. The ability to emulate the push of a button using haptic feedback greatly improves the reliability (plus water and dust proofing) of the iPhone by reducing the number of moving parts in the assembly.

Bottom left corner of the iPhone 7 showing the lack of a 3.5mm audio jack

Figure 4. Bottom left corner of the iPhone 7 showing the lack of a 3.5mm audio jack

The empty space found in place of the audio jack in the previous x-ray image initially got us thinking that the audio jack was removed for nothing. However, further investigations when opening the iPhone showed us a new plastic component in that location, as seen in Figure 5.
According to Apple, this plastic component is a barometric vent. With the added ingress protection afforded by the watertight seal, the iPhone uses this baffle to equalize the internal and atmospheric pressures in order to have an accurate altimeter.

REPAIRABILITY
The ability to rework wearable devices and smartphones is critical to the subsistence of a growing number of companies in the market of fixing these devices. As seen in Figure 6, the x-ray of the new iPhone 7 Plus shows it is a very complex device with thousands of parts and a complicated process to disassemble. These are expensive devices that can easily be damaged by a single drop on the floor.
The repair market is a $4B/year worldwide industry dedicated to bringing very expensive devices back into commission. The focus of these companies is on the repair and replacement of displays and screens, battery, button and headphone jack (no longer an issue in the iPhone 7), camera and sensor.
To assist in the assessment of the level of difficulty to repair these devices, ifixit [2] has rated several smartphones and wearables in the market today. Table 1 shows a small portion of this dataset.

Repairability scores of major smartphones launched since 2010. A score of 10 represents a device that is the easiest to repair

Table 1. Repairability scores of major smartphones launched since 2010. A score of 10 represents a device that is the easiest to repair

This data show that since 2010 the iPhones have been relatively easy to repair. That’s mostly given the fact that the first thing you remove from the iPhone is the screen – and because the screen is usually what you are trying to replace.

X-ray image of the iPhone 7 Plus showing the internal complexity of the device

Figure 6. X-ray image of the iPhone 7 Plus showing the internal complexity of the device

Once the screen is removed, the battery is easily accessible. The Samsung phones, on the other hand, have been decreasing in repairability score. The Galaxy S3 was assembled with a very easy to replace battery. The display was somewhat challenging, but nevertheless achievable. However, the new S7 was built with very high tolerance that make it very difficult to repair because [2]:
• The display needs to be removed (and likely destroyed) if you want to replace the USB port.
• Front and back glass make for double the crackability, and strong adhesive on the rear glass makes it very difficult to gain entry into the device.
• Replacing the glass without destroying the display is probably impossible.

FUTURE TRENDS

Water Proofing
We foresee water proofing as a major trend that is driving the electronic design and manufacturing of most wearables and smartphones today. The new iPhone 7, for example, is water resistant to IP 67. However, it is not water proof. The distinction is significant, both from a user experience and manufacturability perspectives. The technologies associated with water proofing electronics such as conformal coating design, application, and inspection, will continue to be the focus of future manufacturing R&D.

Battery Technologies
As we can see in Figure 1, batteries still take at least 50% of the real estate inside all modern wearables and smartphones. For this reason, a great deal of R&D is focused on increasing the power density of batteries. A smaller battery directly impacts the amount of features – and sensors – that manufacturers can include in their devices. We foresee that super caps will make their debut in the world of smartdevices in the next 5 years.

Wireless Charging
Apple debuted wireless charging in 2015 with the first edition of the Apple Watch. Although wireless charging has gained mainstream status by other major OEMs – Microsoft, Samsung, Sony, Lenovo – it is still to be found in the iPhone.

Wafer Level Chip Scale Package (WLCSP)
The Apple Watch has one of the densest electronic packages we’ve encountered in our teardowns so far. The system in a package unit (S1 in the 2015 edition of Watch, and S2 for the second edition) is almost fully assembled using WLCSP. As seen in Figure 7, WLCSP is one of the densest packaging technologies available, to the point where the package does not exceed the size of the bare die by more than 20% and solder ball pitch is not larger than 1mm. Handling and assembling these WLCSP devices is a big challenge for SMT contract manufacturers, one that in most cases requires considerable investment in capital equipment for assembly and inspection of these assemblies.

Right: Example of Polymer-RDL WLCSP construction. Left: X-ray inspection of WLCSP package

Figure 7. Right: Example of Polymer-RDL WLCSP construction. Left: X-ray inspection of WLCSP package

The photograph overlaid onto the x-ray of the decapsulated S1 in Figure 8 exposes its array of WLCSP devices and a quick snapshot of the supply chain for the Apple Watch [4].

Figure 8. Apple Watch’s S1 system in a package

Full Wireless Interface
It is clear that the smartphone industry is leading to the consolidation of the wireless charging standard. Most wearables have already adopted the technology. When water and dust proofing a device, connectors are always the main weak points of the design. Thus, eliminating connectors all together is further incentivized by the need to fully seal the devices, as seen in Figure 9 [2].

Figure 9. Apple Watch 2 after complete teardown showing the full operation of the device via NFC

It was surprising to see that the new iPhone doesn’t have a wireless charger, especially when considering that most high-end Android devices already do. However, Apple surprised some users by removing the 3.5mm audio jack. This was, we believe, the first step in the company’s strategy to converge towards a fully wireless architecture for its iPhone line. All battery charging and communications will be done wirelessly, thus removing the need to deploy any connectors in the device. This will further impact the water resistance or proofing rating of the next iPhones. It will also allow Apple to continue pursuing ever thinner devices. We may see such a revolutionary model as early as 2017, when the company is said to bring to market a groundbreaking device for the iPhone’s 10th anniversary.

Cameras
The new iPhone 7 Plus is equipped with two 12 MP cameras (see Figure 10) – one wide-angle with Optical Image Stabilization (OIS), just like in the iPhone 7, the second a telephoto – allow for optical zoom. The multiple camera trend will continue, as improvements in software and image processing will allow companies to leverage different lens modalities to deliver superior user experience. That also means that contract manufacturers ready to take on challenging mechanical assembly jobs will likely benefit from this trend.

Dual 12MP camera from the iPhone 7 Plus

Figure 10. Dual 12MP camera from the iPhone 7 Plus

Memory
The pursuit for the increasing storage space will continue. Albeit continuous efforts by all major OEMs to move our data to (paid) cloud storage services, local storage still a growing necessity. Some of this need has been driven by a steady improvement in camera resolution, which continues to require increasing levels of data storage.

CONCLUSION
The process of tearing down popular consumer electronics will continue as a means to gain some insights on how the large companies work and develop their products. In this paper we presented a few of the ideas we have collected on recent teardowns. The major forces in SMT manufacturing will continue pushing US manufactures toward miniaturization. The number of WLCSP devices we find in major devices continues to grow, which tells us they are on their way to becoming a standard.
The impact of this transformation may not be instantaneous. If you are a small or medium contract manufacturer in the US, for example, you can think that these trends don’t impact you. But they do, and here’s how. Even though your customers are not designing product with WLCSP, they will soon not have an option because the large volume players in the market – and the ones the component manufacturers cater to – will give preference to WLCSP. This is a continuous process, similar to what happened to the thru hole components. We still come across manufacturing companies that are now migrating to surface mount components. Progress is inevitable.

X-Ray Specs History


German physicist Wilhelm Röntgen is usually credited as the discoverer of X-rays in 1895, because he was the first to systematically study them, though he is not the first to have observed their effects. Roentgen called it “X” to indicate it was an unknown type of radiation. The name stuck, although (over Roentgen’s objections), many of his colleagues suggested calling them Roentgen rays. They are still occasionally referred to as Roentgen rays in German-speaking countries.
The methodology used to create x-ray images is still a matter of confusion to many people. The fact you need an x-ray source and a special x-ray sensor to produce an image makes the fabrication of the infamous “X-Ray Specs” a matter of science fiction. That’s why Chris Baraniuk’s article titled “The Secret History of X-Ray Specs” caught my eyes. The single fact you need to ask the question shines some light on the confusion about the technology. Remember that in the early days some people made money riding the wave of mystery and confusion with “products” like these:

Unfortunately some x-ray companies still rely on these “smoke and mirrors” techniques to sell x-ray machines. That’s why we spend a lot of our time doing the best we can to educate our customers about x-ray inspection. What’s possible, and perhaps more importantly, what’s not possible.

X-ray Inspection of Lead and Lead-free Solder Joints

September 27, 2:30PM

X-Rays are widely used to inspect solder joints in the electronics industry. As aerospace companies consider the shift to lead-free solder alloys and glues, concerns have been raised about whether their current x-ray inspection and quality-control procedures will still be valid. With lead solder, joints are easily interpreted by the operator or the system imaging software because lead provides excellent image contrasts due to relatively high X-ray absorption compared to that of PCB and component materials.

The first thing that caught our attention to the new Misfit Ray is how small this activity tracker is. At 1.5″ in length and only 0.5″ in diameter, this little tube houses all the electronics plus the batteries to power the bluetooth radio, 3-axis accelerometer, multicolor LED display, and the piezoelectric vibration. What’s interesting is Misfit’s choice not to use rechargeable batteries. Instead, they opted for the standard 393 button cells you can find at most grocery stores in the US. That choice of battery means that you don’t ever need to recharge the Misfit Ray – thus no need for a connector (which makes sense for a water resistant device) or a recharging circuit (where to put it anyway?). The length is for the most part driven by the average size of a person’s wrist: make it a bit too long and the Misfit Ray will look awkward around your wrist. You can fix that by making the device curve to follow the line of your wrist, but that makes things much more complicated. The cylindric design choice makes to an easy to mechanically fabricated and assembly device – but makes the electronics very challenging! See it for yourself in the following video. Note how the talented engineers at Misfit had to fully utilize the roughy 1/2 inch allocated for the electronics in 3 dimensions. To accomplish that they designed a mezzanine card that sits right on top of the main board. Both boards are connected via a flexible circuit. We extracted the rotation video as a gif so you can appreciated the work of art done by our fellow engineers at Misfit!

What, Counterfeit Network Equipment?


The counterfeit detection community has spent the past several years developing techniques to determine if an electronic component is fake. Our team has done a lot of work developing x-ray machines and custom algorithms to find counterfeit electronic components. However, we have not been looking for counterfeit components already mounted on the PCB and sold as a finished piece of equipment. In this case the simple replacement of a component for a fake is not the worse case scenario. Things get really worrisome when you consider that this “fake” component can be used as a threat to our cybersecurity.

As an example, the following x-ray images show an authentic memory chip (left) and a counterfeited one (right). Note that externally, when inspecting these components under a microscope, these two devices look identical. Also, they were found in the same reel of components, sitting side by side in neighboring pockets.

Counterfeit-components-x-ray

Our recent work presented at the latest Symposium on Counterfeit Parts and Materials shows how a TruView x-ray inspection system in conjunction with ICARUS was used to find extra parts added to a network equipment. This work also shows how these devices – and any other – can be inspected inside the box (no need to void manufacturer’s’ warranty) to determine if the device inside the box is what you expect it to be.

Check out these x-ray images, can you tell the differences between them? It’s hard to see given the complexity of these images, so we added a small red box to call your attention to the corner of the image on the right. These two pieces of equipment should look identical on the x-ray, so what is that extra circuitry doing in that corner?

Since this topic is new and there has been a lot of interest from different agencies, we’ve been asked to keep this info under control. Therefore we decided to keep the presentation and white paper from our website. If you’d like a copy please email us at info@creativeelectron.com.

Counterfeit Electronics Symposium


We’re looking forward to presenting and exhibiting at the upcoming Symposium on Counterfeit Parts and Materials. We’ll be in booth #1. Our paper “The Next Challenge For X-Ray Counterfeit Detection: Electronic Equipment” will show new challenges OEMs are facing with elaborate counterfeit schema.

Abstract:

For the past years our R&D team has presented new algorithms and technologies related to the use of x-ray inspection to identify counterfeit electronic components. Although a critical part of the electronic industry’s value chain, single components are not the only target of criminal enterprises. This year our presentation will focus on another equally important stage of the value chain: electronic equipment. The work presented reflects research and development of hardware, software, and algorithms needed to perform x-ray inspection of routers, switches, and other high monetary value equipment. In specific, we will focus on a case study where a number of routers and switches that were not only counterfeited, but also replaced with other electronics. X-ray images of these devices will be presented, as well as the algorithms utilized to assess the authenticity of these equipment.

TruView™ H – The Horizontal X-Ray Machine

by Bill Cardoso in Creative Electron Comments: 0

There are several applications out there that require the x-ray inspection of vertical samples. For example, if you want to check the fill level in a vial of paint. In this case you can’t lay the sample flat on the stage – which is required in a vertical system (most x-ray machines out there). Instead, in the TruView™ H the x-ray source and sensor are placed in such a way that the beam is horizontal, thus allowing the sample to be inspected standing up. For more details please visit TruView™ H X-Ray Inspection System.

APEX 2016: The Making of


As we head back to California from another amazing IPC APEX show in Vegas, we thought it would be interesting to write a bit about all it takes to make a show like that happen. It all starts months prior to the show. Tom spends a lot of time figuring out the logistics so that everything is ready for our team when they land in Vegas. We drive our delivery trucks – good old F150’s – with the machines we will exhibit plus all the marketing materials we give away.

The exhibit started on Tuesday, so we loaded the trucks early Monday at 3AM. Here’s a shot of our team (Griffin and Jesse shown here) hard at work early that morning loading one of the trucks with a TruView 200.

Early Monday morning we started our journey to Las Vegas, which took us around 6 hours!

sanmarcos-to-vegas

The work to assemble the booth starts as soon as we got there. As you can see, Brian and Griffin were diligently at work making sure everything is good to go.

20160323094636

Our friends from Tharium Corporation were there as well. Francisco Sanchez did a great job demonstrating the new image comparison features of the IRIS camera!

Tharium-APEX2016

The show was very successful. It was a great opportunity to meet new people and to catch up face to face with our sales representatives from around the world. Thursday afternoon, after the show was over, it was time to pack it all up again and head back home. We were done packing the trucks around 5 that day; ready for another 6h drive to SoCal!

Things were going great until the GPS in one of the trucks stopped working around Barstow. It was not a bigger problem because the driver was very familiar with the way back from Vegas. The GPS unit is powered from the 12V power source inside the cabin, which for some reason stopped working – likely due to a faulty fuse. Needless to say the first thing when we arrived in the office was to x-ray that fuse!

open-fuse

There you have it! It was a 20A fuse that blew half way back home. Looking in the interwebs it seems that this is a common issue with the F150. But nothing that a quick visit to Pep Boys didn’t solve.

For those we only see at the IPC APEX shows, we are looking forward seeing you again next year here in San Diego. In the meantime, be well, do good work, and keep in touch!

Epinephrine Auto-Injector Teardown


For millions of people around the world, having an Epinephrine auto-injector can mean the difference between life and death. According to the National Institutes of Health (NIH), the Epinephrine injection is used along with emergency medical treatment to treat life-threatening allergic reactions caused by insect bites or stings, foods, medications, latex, and other causes. Epinephrine is in a class of medications called alpha- and beta-adrenergic agonists (sympathomimetic agents). It works by relaxing the muscles in the airways and tightening the blood vessels.

According to Reporterlinker.com,  2.45 billion of these syringe units were sold in 2011 with an expected  3.59 billion to be sold in 2015. Pre-filled syringes form one of the fastest growing markets in healthcare.The devices contain a spring-loaded needle that exits the tip of the device (in some cases through a sterile membrane) and penetrates the recipient’s skin, to deliver the medication via intramuscular injection.

To show you how these incredible devices work, we did the teardown of one of the most Epinephrine Auto-Injectors in the market, the Epipen®. As you can see in the following x-ray image, there are 5 key parts of this auto-injector. Let’s start from the top of the Epipen® (5), which is the actuator (or button) you press to trigger the pen. This trigger releases a powerful spring (4) that can apply several pounds of force to release the medication inside the syringe (3). This force also causes the needle (2) to exit the auto-injector and penetrate the patient’s skin. To absorb some of that impact, the release spring (1) takes some of that shock to provide the patient with a smooth experience (similar to the shock absorbers in your car).

There’s a lot of information on this topic online. We found the Mayo Clinic website specially useful.

Teardown: Why is it Important to See What’s Inside Our Gadgets?
Dr. Glenn Thomas, Creative Electron
The impulse to break a new gadget to “see what’s inside” is often the first sign someone will become an engineer. However, modern teardowns go far beyond pure curiosity: they provide us critical insights into the nature and construction of these devices. In this talk we will cover the teardown of several gadgets, from the early Blackberries to the Apple Watch, to understand how the SMT industry has changed. These findings will also help us forecast where we are going as a community by discussing miniaturization and packaging, automation and labor force location, device features, and other important topics. These are key issues we need to address to keep U.S. SMT manufacturing relevant.

Find Counterfeit Components with TruView X-Ray Inspection Reel-to-Reel


The success of our global economy relies on the free flow of information and products across multiple geographical boundaries. In a networked society, markets transcend political borders to reach every corner of the globe. With such connectivity come serious challenges to protect the homeland from foreign and domestic threats. The influx of counterfeit electronic components in our supply chain is an ever-increasing threat to our economy. The latest report issued by the US Department of Commerce states that the number of counterfeit incidents almost tripled between 2005 and 2008.

Radiography (or x-ray inspection) is a ubiquitous technique to all recent and upcoming counterfeit component detection standards, including IDEA 1010B, CCAP 101, AS5553, AS6081, and AS6171. X-ray inspection gives you the unique ability to “see” what is inside an electronic component without damaging it.

TruView X-Ray Inspection Reel-to-Reel System

TruView X-Ray inspection system with embedded Reel-to-Reel System

Our team has been working for several years to bring to market solutions that allow our customers to inspect 100% of parts in tape and reel, tubes, and trays. We are proud to share with you today that another major step in our patent-pending Reel-to-Reel (R2R) system was completed: it is faster than ever! Not long ago it took our R2R over 30 minutes to inspect 1,000 parts. That was a breakthrough at the time, but we were not satisfied. Continuous work on this technology have lead us to a new R2R system that can inspect up to 1,000 parts in 5 minutes. This performance allows our partners to drive up inspection of components, thus greatly reducing the chances counterfeit components will be inserted in the supply chain. For more details please take a look at the following video:

Reel to Real: An X-Ray Parts Counter


 

Counting parts is an integral part of any inventory control activity. Inventory is cash, and the ability to quickly assess how many parts you have in inventory is critical to the success of any manufacturing company. Counting parts on reels has been a daunting task: open the ESD bag, load the reel-to-reel counter, run it, re-reel, place reel back in the ESD bag. Of course, hope no damage was done to the components in the process. Ah, since the parts counter counts the number of holes in the tape (not the components per se), also hope the count is close enough to reality.

Large area x-ray detectors allow us to take a large image of a reel of components, like the one seen here:

push_buttons

Then using custom software, we count how many components are in the reel. That’s it, simple and direct – and accurate – counting for your inventory control. To make things even easier, we embedded this functionally to our TruView SRT, which gives you simple and fast operation.

Check out our demonstration video, and as usual, contact us if you have any questions.

TruView SRT: Simplicity is the Ultimate Sophistication


 

As it is true with most technology companies, our R&D team works tirelessly in the development of algorithms, software, and hardware that improves our products. In this continues – and perhaps limitless –  pursuit of a “better” product, we must be careful not to loose touch with the end user. We live in a very pragmatic world populated by educated users who come to us with deep knowledge of their needs. For that reason, sometimes the biggest technological advances come in the simplicity of the machines we make.

We designed the TruView SRT with a “less is more” motto. An interface with a few discrete push buttons replaces the traditional keyboard/mouse user interface. A minimalist software design replaces the app driven environment of TruView 6. We recognize that some users need a Swiss Army knife and some only need a good screwdriver. The TruView SRT is a plugin system ready for action!

Check the introductory video for more information, and as usual, contact us if you have any questions.

Fun with X-Rays!

by Bill Cardoso in Creative Electron Comments: 0

We had a great time having fun with x-rays this last weekend. As advertised, we offered free Halloween x-ray inspection in our facility in San Marcos, CA. The main purpose of this activity was to show kids (and their parents) the joy and beauty of x-ray inspection. Dozens of kids were able to see, for the first time, x-rays in action! If one of the them decides to follow a STEM career because of this experience – mission accomplished!

Of course candy wasn’t the only thing we x-rayed, after all it was time to experiment. Several toys were inspected in the process, including Thomas the train, BB8, and Hot Wheels cars, and much more. Check out some of the images we got. We look forward to another Halloween x-ray inspection session next year!

Free Halloween Candy X-Ray


Over the years we’ve seen several reports of criminals inserting foreign objects in Halloween candy. For that reason we use x-rays to make sure the candy our kids collect is safe for consumption. This year we decided to offer this service to the whole community. If you’d like to have you kid’s candy inspected with x-rays, please come by our facility in San Marcos this Sunday, November 1, from 9AM to 11AM. We’re located at 253 Pawnee St., San Marcos, CA. If you like more information, feel free to contact us here. This is not only an opportunity to check candy for foreign objects, but also a chance to show your kids how x-rays work. We look forward to seeing you this Sunday!

To give you an idea of what we can see if x-rays, check these images of what an innocent Snickers or Reese’s Peanut Butter Cup can hide!

Although both examples are simulated, I can’t imagine finding these objects in my kids’ bowl of candy like other parents have! Here’s an example of the x-ray of the whole bowl showing the needle and the razor blade.

Halloween-Candy-Bowl

What can we find inside Halloween candy using x-rays?

Before we get into the details of what we can and cannot see inside our kids’ candy, let’s review how x-ray imaging works. A special source located underneath the candy produces x-ray photons (x-rays photons are similar to visible light photons, but they vibrate at different frequencies) that travel thru the candy and reach a special sensor located on top of the candy. Unlike visible light, these x-ray photons travel go thru matter. However, we can tune the energy of the x-rays so they stop at some heavy materials (like metals), thus creating a shadow on the sensor. Now imagine we collect a bunch of these x-rays and create a image based on the density of the material they are travelling thru. Like you can see in the above image, the heavy parts of the candy are darker than the light parts of the candy. The metal foreign objects can be seen because they stop almost all x-rays, thus creating a very dark profile of the object (see the needle and the razor blade). What’s really cool is that we can also see the peanuts inside the Snickers bar and little air bubbles inside the Reese’s Peanut Butter Cup! What we can’t see, however, include materials that don’t cast a shadow with the x-ray light. That includes poisons, paper, aluminum, plastic, and other light materials. Like everything in life, technology can’t replace good judgement. X-rays can help us some things, but not absolutely everything a criminal might decide to insert in a candy.

Have a safe and happy Halloween!

The All New TruView Flex is Here!


It took us a while, but the TruView Flex is finally here! For those who have not been part of this development, the TruView Flex is a unique x-ray inspection system because it can be used as an offline  or as an inline machine. It has shutters on both sides of the machine and a conveyor belt inside, so that we insert a sample from one side, perform a full automated inspection of the sample, and spill it out from the other side. In offline mode, the system automatically closes the shutters so that you can run a manual or automated inspection using the joystick in front of the system. We also added a pass through mode so that the TruView Flex behaves like a standard conveyor belt to move the samples from one side to the other.

OnePlus 2 = Awesome Teardown


Here’s another awesome teardown with our great friends at iFixit.  The OnePlus 2 is the OnePlus’ newest venture in the world of smartphones. The self proclaimed “Flagship Killer”, the OnePlus 2 (can we call it 3?) has very competitive specs. Starting at $329, this is an interesting option to those looking for an Android experience.

Here’s one of the x-ray images you’ll find in the teardown. One of the highly publicized items of the OnePlus 2 is its 13MP camera. Wonder what OnePlus has to say about it?

“Despite being a go-to measure for smartphone cameras, megapixels fail to tell the whole story. The true test of a camera is the quality of its image sensor and optics. Our sensor contains large 1.3µm light-collecting pixels—the biggest ever in a 13MP smartphone camera—for unmatched low-light performance. A six-element lens prevents distortion, making sure that photos are clear and crisp. Day or night, make every shot beautiful.”

And here it is from the inside out!

Inside the Amazon Dash Button – X-Ray Teardown


The new Amazon Dash Button – now available to Prime members – is the ultimate step in convenience shopping. If you haven’t seen it yet, the Amazon Dash Button allows you to buy a specific product – in this case Huggies diapers – at the click of a button. This little device communicates to your Amazon Prime account using the local WIFI network. The setup of the device is easy, all you need is a smartphone (iPhone or Android) with the Amazon App. Follow a few steps, and your account settings are sent to the Dash Button using the speaker of your phone to the microphone in the Dash. You can actually hear as your data is sent to the Dash!

Now let’s look inside this new Amazon device, starting with a 360 rotation of the Dash and the animated overlay:

Creative Electron Granted Patent for Acoustic Mirror Array


We’re happy to report that we’ve been granted patent US 9084057 titled “Compact acoustic mirror array system and method”.  Microphone or sound detecting systems typically comprise a single microphone physically encased in an isotropic material (e.g., wood or plastic) with an open aperture for omnidirectional or for hemispherical sensitivity. Consequently, the bulk of improvements in modern microphoning technology have primarily been directed to developing better microphonic circuits (e.g., amplifiers, signal processing) or to better microphonic hardware (e.g., piezoelectrics or electromagnetic microphones). Accordingly, there has not been any significant advancement in the use and configuration of specialized materials for the microphone casing or for lensing/amplifying effects.

Therefore, there has been a long-standing need in the sound and microphoning community for new methods and systems that address these and other deficiencies, as further detailed below.

The following presents a simplified summary in order to provide a basic understanding of some aspects of the claimed subject matter. This summary is not an extensive overview, and is not intended to identify key/critical elements or to delineate the scope of the claimed subject matter. Its purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.

In one aspect of the disclosed embodiments, a microphoning assembly is provided, comprising: a sound directing structure having an acoustic focus, a portion of the structure having a sound-affecting physical property that that directs a wave front of incoming sound to the focus; and a microphone situated substantially proximate to the focus to pick up the directed sound, wherein an increase of at least 10 dB is experienced at the microphone as compared to non-directed sound.

In another aspect of the disclosed embodiments, a method of enhancing the detection of sound is provided, comprising: forming a sound directing structure having an acoustic focus, a portion of the structure having a sound-affecting physical property that that directs a wave front of incoming sound to the focus; and situating a microphone substantially proximate to the focus to pick up the directed sound, wherein an increase of at least 10 dB is experienced at the microphone as compared to non-directed sound.

What’s Inside Your Wallet?


This week we will take a look at an item ubiquitous to all of us: credit cards. Not sure if you noticed, but the old credit card that you used to swipe at the store is slowly being replaced by Smart Cards that you instead insert in the payment machine. Perhaps Smart Cards will be obsolete before taking over if the electronic wallets of Apple, Google, PayPal, and others take off fast enough. Since the adoption rate of electronic payment system (e.g. Apple Watch) is reasonably slow, the Smart Card has a fighting chance. After all, the Smart Card Alliance estimates 600 million Smart Cards will be in use by the end of 2015 in the US alone.

credit-card-x-ray

The “smarts” in the Smart Card come from the tiny microchip embedded in the card, as you can see on the left top corner of the following image. As usual, we give you the photo of the card overlaid with the x-ray of the card.

creditcard

Smart Card x-ray image and photo

So why bother putting a tiny microchip in your credit card? Other than being super cool to we geeks out there, this microchip was designed to reduce the ability of criminals to steal your credit card. How? Simple: the old credit card has a magnetic strip with all your data (remember old cassette tapes – similar technology). Well, to copy or clone your credit card all the criminal needs to do is to read the data in the magnetic strip and record it into a blank card. Voila, your card has now a twin sister!

To make criminals’ life harder, the microchip in the Smart Card generates a new code each time you use it. Once used, the code is no longer valid. This code is specially generated so that the credit card companies know it’s your card being used. It’s useless for the thief to steal the code, since it changes with every use. Pretty cool, right?! Here are more details of the chip itself, and the little wires that connect the chip to the pads on the credit card. These are the golden looking areas on the corner of the card. They are used to complete the electrical contact between the payment machine at the cashier and the microchip inside the card.

I’m sure you won’t see your credit cards the same way again. And please use your card responsibly!

 

Life, Liberty, and the Pursuit of the Perfect X-Ray Machine

by Bill Cardoso in Creative Electron Comments: 0

liberty-bell-xray-labelX-ray of the Liberty Bell – Courtesy of National Parks Service

“We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.” Jefferson’s phrase in the 1776 Declaration of Independence is undeniably one of the key pillars of the American project. Strangely enough, that was the first time in history that anyone had bothered to write it down. This phrase also explains the key driving force of this nation: meritocracy.

Meritocracy is the idea that your age, gender, race, education, and your job history don’t determine who you are or what you can do. Instead, your destiny is driven by your creativity and work ethic. The ability to recognize an opportunity, and to act on it efficiently, trumps all other factors. If you can get the job done, people don’t really care where you come from. Meritocracy is the core driving force in the company I founded a few years ago, Creative Electron. I’ve found meritocracy to be an effective guiding principle to keep us focused on what’s important: our customers.

It was with these principles of freedom and meritocracy in mind that a few months ago we set to develop the next generation of x-ray software to power our TruView X-Ray Inspection Systems. The main change we made was to open the TruView Software to the scientific community. TruView 6 X-Ray Software has the capacity to harness the invaluable amount of untapped talent because it serves as a core software platform (similar to the iOS or Android operational systems in your smartphone). TruView 6 builds on these experiences to leverage crowdsourcing so that scientists can write Apps and share them in our TruView App Store (once approved by our team to assure the quality and security of the code).

To think about crowdsourcing as a creative source to your company can be scary at first. But going back to what I said about customer centricity, our goal is to provide our customers with the best possible x-ray machine. Thus, why not allow our TruView software to be a development platform for talented scientists and researchers? Why not leverage the immense power of the scientific community to bring these ideas to our customers? In his “Crowdsourcing” book, Jeff Howe writes, “crowdsourcing has the potential to correct a long-standing human conundrum. The amount of knowledge and talent dispersed among the numerous members of our species has always vastly outstripped our capacity to harness those invaluable quantities”.

In the first few days since its launch, the requests from top universities and research laboratories to develop Apps for the TruView platform is a fantastic validation that crowdsourcing works. It’s also validation that all the efforts and investments to develop TruView 6 will pay off. In the end, what really matters is that our customers will greatly benefit from the creation of new apps that will meet their every x-ray inspection need.

A small team in Southern California develops every TruView product. We all share the same office. We also share an obsession for building the best x-ray machines in the world. TruView 6 is allowing us to meet like-minded passionate people with incredible ideas, and we welcome them to our team! I love the fact that our small team can now harness the creative power of the crowd to deliver amazing products to our customers. I love the fact we can share the principles of freedom and meritocracy worldwide, and to continue to brand every one of our TruView X-Ray Inspection systems “Proudly Designed and Made in USA”.

What are your experiences with crowdsourcing? Please comment and share your thoughts on the matter.

Fitbit Charge HR Teardown with X-Rays

by Bill Cardoso in Creative Electron Comments: 0

fitbit-teardown-icon-x-ray

Today we get to teardown the super popular Fitbit Charge HR. This is an elegant and simple smartwatch/fitness band – a major contrast to the exuberance of the Apple Watch. Of course, the tiny display in the Fitbit is no comparison to the gorgeous display of the Apple Watch. Albeit its simplicity, the Fitbit Charge HR packs a lot of technology: full time heart rate monitoring, caller ID, exercise tracking, and wireless syncing. All that with an incredible battery that lasts almost 6 days. I specially like how thin the Fitbit Charge HR, making it an easy accessory to use everyday.

Let’s start by checking out these animations that overlay the x-ray image of the Fitbit Charge HR with its photos:

Top View

fitbit-top-x-ray-animated

 

Side View

fitbit-side-x-ray-animated

The first x-ray image we took of the Fitbit Charge HR, looking from the top of the device, shows the two large mounting screws on the top of the image. The “G” like structure you see on the center looks like the antenna used to wirelessly sync data. The large IC right below it seems to be communication IC in a QFN package, which by the way has a fair amount of voiding… as you can see in our X-Ray University,  large amount of voids underneath a QFN can lead to excessive running temperatures and shorter IC lifespans.

antena-Fitbit-Charge-HR

The Fitbit Charge HR uses a traditional rotary vibration motor, as seen in the following x-ray image. The darker area around the shaft is the weight used to vibrate when the motor is turned on.

vibration-motor-Fitbit-Charge-HR

This nice image of the heart of the Fitbit Charge HR shows the complex electronics packaged in the device. The larger BGA in the top left of the image shows the main control IC. Those horizontal lines on the center of the image are nothing but the connector used to interface the main board to the display.

main-pcb-Fitbit-Charge-HR

 

Here’s a nice detail of the pushbutton on the side of the Fitbit Charge HR. Note the mechanical reinforcement soldered to the board. That large dark circle on the bottom left is one of the two charging pins. More about that later.

button-Fitbit-Charge-HR

This beautiful image shows a side view of the Fitbit Charge HR, in the exact place where the battery connects to the main board. The battery is the large object on the right of the x-ray with the several horizontal layers. The vibration motor can be seen on the left of the image.

battery-Fitbit-Charge-HR

Here’s a very nice image showing the charging pins of the Fitbit Charge HR. Look carefully and you can see the little springs inside the pins, which provide mechanical compliance to the device when Fitbit Charge HR is connected to the charging cable. The heart rate monitor can be seen on the top of the image, while the bottom of the image shows the OLED display.

LG G4 Teardown with X-Rays

by Bill Cardoso in Creative Electron Comments: 0

 

Last week we spent some quality time with our friends at ifixit.com tearing down the new LG G4.  Other than the genuine leather finish, the G4 packs an incredible set of specs that include a beautiful 5.5” display with 2560 x 1440 of resolution (Quad HD – 538 ppi), a removable battery, and up to 2TB in the microSD card. It’s clear LG designed the G4 to cater to the users who complained about Samsung’s decision to drop the replaceable battery and microSD card on the new Galaxy S6. To make the point clear, LG is offering a free 32GB microSD card and an extra battery pack, if you buy your G4 by the end of the month.

The G4 looks great on the outside – let’s see how does it look inside!

How does WISE improve x-ray inspection?


X-ray inspections need good quality images so that features in the material can be observed. The Wavelet Image Spectra Enhancement (WISE) technique was developed as a set of powerful filters designed to improve the quality of x-ray images. The overall quality of these images is critical to a successful  x-ray inspection. In this paper we describe…

Creative Electron launches new TruView AXI


Creative Electron launched its new line of automated x-ray inspection (AXI) equipment at the 2015 IPC APEX EXPO in San Diego. At the show, the company demonstrated the unique capabilities of the new TruView AXI.

TruView-AXI-Model2

The all new TruView AXI

“We spent the past two years working with our customers to develop an automated solution platform that meets and exceeds the x-ray inspection requirements of the surface mount industry, with emphasis in LED, BGA, QFN, and CSP analysis and diagnostics,” said Dr. Glen Thomas, Creative Electron’s VP of Marketing. Dr. Thomas added, “One of the key benefits of the Creative Electron TruView AXI’s performance is the flexibility – a major advantage for customers that are inspecting batteries and other mechanical assemblies.”
The new TruView AXI platform automatically captures and analyses x-ray images from PCBAs, providing consistent inspection results and eliminating operator error. What differentiates the TruView AXI from other systems in the market is a set of exclusive algorithms used to determine sample is defective or not. To further improve the operator’s ability to diagnose a PCBA, the TruView AXI includes ICARUS, Creative Electron’s image analysis software package. “The layering of image processing algorithms – AXI and ICARUS – gives the TruView AXI unique capabilities that will help our customers find defects in their assemblies with higher confidence than ever before,” said Griffin Lemaster, Creative Electron’s VP of Engineering.

TruView Dual Energy: a New Way to See X-Ray Inspection


Since the first x-ray images were created, operators of radiography systems have been challenged by a fundamental shortcoming of x-ray inspection: material density variation. While inspecting a sample of any sort, it is usual to find materials of different densities sitting side-by-side. Examples of this situation include dense electronic components (transformers, power amplifiers, etc.) mounted on boards, BGA balls, heat sinks, bones, and metal casings.

The challenge is that operators have to turn down the power of their x-ray system to image the low density materials. However, the low energy x-rays do not penetrate the high density materials, which will not create an image (under-expose). As a result, the power of the x-ray source must be increased to expose the dense parts of the sample at the expense of over-exposing the low density parts.

With the Dual Energy toolbox in your TruView X-Ray system this is finally no longer a problem! The patent-pending algorithm allows you to first take the low energy image of your sample. The next step is to take a high energy image to expose the high density parts of the sample. The Dual Energy toolbox automatically blends both images – low and high energies – to produce incredible images that show you what you’ve never seen before: high and low density materials beautifully exposed side by side!

The first example is a wire crimped connector. The connector has a low density plastic casing that houses the high density metal crimps and wires. As seen in Figure 1, the attempt to image the high density material completely washes away the low density plastic housing. Au contraire, the image in Figure 2 shows that the low energy image perfectly displays the plastic housing of the connector while completely masking the wires and crimps.

X-ray-Bad-Connector-high

Figure 1 – High energy x-ray image of wire connector showing crimped wire and high density material

X-ray-Bad-Connector-low

Figure 2 – Low energy x-ray image of wire connector showing plastic case and low density material

The patent-pending Dual Energy toolbox in TruView 5 Software was used to image both low and high energy parts of the connector and show them simultaneously, as seen in Figure 3.

X-ray-Bad-Connector

Figure 3 – Dual energy of the crimped wire connector using TruView patent-pending Dual Energy toolbox

The second example we will analyse is the classical ball grid array (BGA). The solder balls in the BGA are very dense, thus a high energy setting of the x-ray source is needed to produce a good image as seen in Figure 4. However, the low density parts around the BGA are over exposed, and therefore cannot be seen. Figure 5 reveals all low energy details of the low density parts of the PCB to expose traces and other features and devices in the board.

Snapshot_000013_XRAY

Figure 5 – Low energy image of a ball grid array (BGA) component showing the low density details. The details around each ball are clearly visible.

Once again the Dual Energy toolbox in the TruView 5 Software was used to merge both images in Figure 6. This figure shows how the Dual Energy image can show both high and low density materials with high resolution.

Dual-Energy-X-RAY-Inspection-BGA

Figure 6 – Dual Energy image of a ball grid array (BGA) component showing the high and low density details. The voids in each ball – and the pads, components, traces, and vias – are also are clearly visible.

The last example we’d like to share with you is of a transformer mounted onto a PCB. As seen in Figure 7, the high energy image shows all the details in the of the transformer. The individual wires are visible in this image. The low energy image in Figure 8 shows all the details of the PCB.

X-Ray Seed Inspection


We recently started a study with the Dairy Focus Laboratory at the University of Illinois, Urbana-Champaign. Under the guidance of Dr. Phil Cardoso, Dr. Glen Thomas (our VP of Marketing) is studying the feasibility of determining the digestive properties of different types of corn. The idea is to develop a method that uses x-ray inspection to effectively assess how the dairy herd will react to a wide range of corn feed. As seen in the following image, preliminary studies have shown that x-ray inspection can effectively determine the variety and density of different types of corn feed.

seeds-x-ray-inspection

 

“A total of 12 varieties of corn were tested using the x-ray inspection methodology we developed. Although preliminary, results so far are very promising,” said Dr. Thomas. “The end goal is to connect the characteristics of the corn x-ray image to milk output. Once we establish this link, we will be able to give researchers a powerful tool to create new feed varieties.” For more information about this study and all other ongoing research at Creative Electron, please contacts us at info@creativeelectron.com or call us at 760.752.1192.

Stencil issues: How X-rays can find what’s wrong


The proper application of solder paste onto a printed circuit board is critical to the success of PCB manufacturing process. Stencils are widely used in SMT applications. In this presentation, we will explore examples of how x-ray inspection can be used to diagnose problems with your stencils.

New vs Old: X-Ray Teardown of MacBooks from 2007 and 2014


In today’s post we compare the x-ray teardown of two popular Apple laptops: 2007 black MacBook and 2014 MacBook Air. Don’t forget to check out the video with the whole process:

2007 Black MacBook

The 2007 version of the MacBook came in two colors, black and white. At the time, the black MacBook was the top of the line in terms of price and performance. This laptop came with a wide range of interface ports – from composite video (later replaced by Thunderbolt in modern Apple laptops) to a real Ethernet connector. The MacBook also had a DVD player, one of the many media made obsolete by Apple. Here’s an animation showing the MacBook and its x-ray image.

macbookblack

2014 MacBook Air

We move forward in time 7 years to show you the latest MacBook Air. The MacBook Air is thinner, lighter, and smaller than its predecessors. However, these gains came at a cost: a small number of interface ports. The DVD player is long gone, and we’re left with 2 USB ports and a single Thunderbolt port. It can be difficult at times to work with the MacBook Air with such limited interfaces. But its size and weight make it a perfect travel laptop. For users who need more interfaces and horsepower, the answer is the Retina MacBook Pro.

macbookair

The Battery Revolution

The following x-ray images show that batteries grew considerably over the years – as the electronics shrunk. We’ve seen a similar trend in the cell phones from previous teardowns – see “A Brief History of Cell Phones“. It is clear that these devices can be made much smaller, however at a sacrifice of battery life.

For the next generation of smaller electronics we need a breakthrough in battery technology!

Plantronics Voyager Teardown by TruView™ X-Ray


For our teardown today we decided to take a break of our smartphone-focused series of posts. However, we didn’t go far. The focus today is the Bluetooth headset by Plantronics, named Voyager Legend.  This is a nice headset – almost 7 hours of talk time, lightweight, and great sound quality. Click on the image for a nice overlay of the Legend’s photo and x-ray:

The Most Advanced Image Comparison Software: ICARUS


It has been several years since we started developing image comparison algorithms for a wide range of x-ray applications. Working on a Homeland Security program, the first application of these algorithms was the automated detection of counterfeit components, where we compared x-ray images of components in reels or trays looking for lot discrepancies. Since then, we have deployed image comparison algorithms for quality control in a variety of applications. A very popular use of image comparison algorithms, for example, is with our x-ray rental and custom units, where these algorithms serve to assist operators in finding defects. For this reason, an algorithm that can tell you what’s different from sample to sample is very powerful.

Although applications change, the premise is the same: a reference image is compared against a set of images that must look identical. Discrepancies must be carefully documented, as they likely signal defects.

The Image Comparison Algorithms for Radiography Unified SoftwareICARUS – is the convergence of over a decade of algorithm development into a unified software platform. ICARUS combines several image comparison algorithms under one umbrella to give you the exact location in the x-ray images that differ from the reference image. ICARUS is a standalone software that works independently of other programs. However, when working in tandem with TruView 5 applications, it allows the user to stop automated acquisitions upon discovery of a fail.

ICARUS can find microscopic differences in the shape, size, and location of features, like broken or bent wire bonds.

To illustrate the power of ICARUS, the following example shows two images with small differences between them. The reference image on the left shows a module without any defects. The acquired image on the center presents a couple of subtle defects: a broken wire bond and a damaged solder ball. These defects were all correctly identified by ICARUS in the right image.

ICARUS-example-x-ray

To improve the effectiveness of its algorithms, ICARUS allows you to select a comparison mask to focus analysis on regions of the image. For example, if you are interested in looking at the wire bonds only, all you need to do is to use the drawing tool in ICARUS to highlight the regions on the image that are of interest. ICARUS also has a powerful registration algorithm used to rotate and translate the acquired image to optimally match the reference image. ICARUS also outputs a complete report of all findings, including a PASS/FAIL result based on image similarity and a programmable threshold. ICARUS is currently in pre-release, and it is scheduled to start shipping November 1.

Please contact us today to see how ICARUS can improve the efficiency of your quality control program.

 

When Counterfeit Components Attack


I know you’re probably expecting another teardown post, but we have something really interesting to share with you today. It’s another post in the series “how counterfeit components can complicate your life”. In the last post on this theme we were lucky to get a video of an electrolytic capacitor exploding. This time we did not get the video, but a photo to share with you – and the x-ray of the damaged part, of course.

There is a lot of talk nowadays on the problems caused by counterfeit components. The problem we see is that the conversation tends to stay at a very high level. The lack of real life examples of counterfeit components creating havoc weakens the discussion. For this reason we will share with you real life counterfeit examples anytime we can to better illustrate the conversation about counterfeit electronic components.

The board in question was supplied to us from a customer – who will need to remain nameless as per their request. We can share that the board is a power supply controller. We can also share with you that this customer uses our x-ray system for overall quality inspection of the PCB they manufacture (BGA, QFN, POP, etc.). However, they currently do not have a counterfeit component mitigation program in place. As a medium size contract manufacturer, they rely on their component distributors to provide them good parts.

The post mortem in this case is straightforward: a component with a lower power rating was remarked with a higher power rating. For most applications that have a large design tolerance, these counterfeited parts might have worked. This application, however, resulted in a nasty RMA. The very first batch of boards tested by the customer led to the flash and smoke shown in the following photo.

Destroyed-IC

 

The x-ray image of this component clearly shows that the power wire bonds, on the same top-right border of the component, have been destroyed.

Destroyed-IC-x-ray

The consequences for the contract manufacturer and their customer in this case, fortunately, were only financial. The CM lost the cost of raw materials and labor to manufacture hundreds of these boards. Their customer is receiving product delayed. As a result of this experience the CM is implementing a counterfeit mitigation program as part of their incoming inspection process. They have also decided to perform periodic audits to distributors in their approved vendors list (AVL) – which, by the way, is rapidly shrinking.

 

 

 

 

 

 

Apple iPhone 6 Teardown by TruView™ X-Ray


We had a fantastic first day at SMTA International in Chicago. We had a chance to catch up with old friends and meet new ones. We also attended some very interesting talks. Talking about old friends, Ed Knutson from Dimation (a quick-prototype contract manufacturer in Burnsville, MN) stopped by our booth for a visit this afternoon. He brought his brand new iPhone 6 for a live teardown at SMTAI. So we put our TruView Cube to action! Here are some photos of Ed’s iPhone 6 ready for the teardown.

We’ve done teardowns of a wide range of smartphones, and I must confess, they don’t look that different from each other. Not a lot has changed from the iPhone 4S to the iPhone 5S. Even when compared to the Samsung Galaxy S5, there are not a lot of new things. The iPhone 6 was a different story. The following images will show you quite a few new features.

But first, here are some specs for the new iPhone 6:

iPhone 6 tech specs: 

– Apple A8 processor with 64-bit architecture

– M8 second-generation motion coprocessor

– 16, 64, or 128 GB onboard storage capacity

– 4.7-inch 1334×750 pixels (326 ppi) Retina HD display

– 8 MP iSight camera (with 1.5µ pixels and phase-detection autofocus) and a 1.2 MP FaceTime camera

– Touch ID home button fingerprint sensor, barometer, 3-axis gyro, accelerometer, ambient light sensor

– 802.11a/b/g/n/ac Wi‑Fi + Bluetooth 4.0 + NFC + 20-band LTE

The first change we noticed was the Apple logo on the back of the phone. Unlike the subtle texture change of the previous models, the iPhone 6 houses a stainless steel logo that shows in our x-ray as clear as day. Perhaps Apple decided to show off for our x-ray teardowns – and for that we thank you Mr. Cook!

Another great improvement of the iPhone 6 platform is the camera. Here’s the x-ray image of the top of the iPhone 6 showing both the FaceTime (right) and iSight (left) cameras. You can also see the flash LED has been beefed up quite a bit. We also noticed a lot of voiding in the assembly of the flash LED. To learn more about what that means please visit LED assembly: how excessive voiding costs you money. We also noticed the 2 MEMS microphones – one to the right of the iSight camera, the other to the left of the FaceTime camera. While the FaceTime microphone is likely used during conversation utilizing the FaceTime camera, the iSight microphone is used to reduce ambient noise from phone conversations. By collecting the voice signal and the ambient noise, a signal-processing algorithm can be used to reduce noise from the data (a.k.a. voice) channel.

iPhone6-cameras-x-ray

This is a nice image to show you the complexity around the new A8 processor… a lot going on around Apple’s new processor.

The SIM card connector is well defined in the iPhone 6. Note the voiding in the solder balls of the connector.

Nice detail shot showing one of the many antennae connections in this iPhone.

Although the speaker assembly channel assembly changed in the iPhone 6, it seems Apple is still using the same speaker as used in the iPhone 5S.

The iPhone 6 has the antennae clearly separated in the design of its case. An aesthetic feature loved by some, hated by others. Here it is seen from the inside out, both left and right of the phone.

Also seen here is the TouchID sensor and the Lighting data and power connector.

It is well known Apple likes to play with the vibration motor in the iPhone products. The iPhone 4 used a counterweight design, the iPhone 4S a linear oscillator, the iPhone 5/5S went back to a counterweight design. For the iPhone 6 it seems we’re back to the linear oscillator idea.


 

We look forward to the iPhone 6 Plus teardown – stay tuned!

Apple iPhone 5S Teardown by TruView™ X-Ray … next: iPhone 6!


The iPhone 6 launched last week – and is already out of stock! In preparation to the iPhone 6 teardown, we went ahead with the teardown by TruView™ X-Ray of the Apple iPhone 5S.

Before we begin, let’s take a look at the 5s specs.

  • Apple A7 processor with 64-bit architecture.
  • M7 motion co-processor.
  • 16, 32, or 64 GB Storage.
  • 4-inch retina display with 326 ppi.
  • 8 MP iSight camera (with larger 1.5µ pixels) and a 1.2MP FaceTime camera.
  • Fingerprint identity sensor built into the home button.
  • Available in three different colors: space gray, silver, and gold.

Looks good on the outside, now let’s take a look inside.

The Renaissance of Made in USA at Maker Faire


It’s 6AM in New York City, and my Southwest flight back to San Diego is ready for takeoff. We spent the weekend here to exhibit our x-ray systems at the 2014 International Maker Faire. If you’re not familiar with the Maker Faire, imagine a combination of a tech show, craft show, and Comic-Con. It’s a place where people come together to share their creative drive – and to air the gadgets they build in their basements. Other than a geek fest, Maker Faire is a place where it is cool to be smart.

Over the weekend we had the chance to meet people like Nigell Dennis, an 18-year-old from Brooklyn who developed and built NAVI, his own Arduino-based smartwatch. Next door to our booth we met a group of rocket scientists who got together to design and manufacture APOLLO, a datalogger that packs 11 sensors in a tiny package. And of course, we also met Richard Carter and his Sashimi Tabernacle Choir. Why do you ask… why not they answer!

The unifying factor in the Make movement is a common drive to innovate. For fun or for business, what united us is the simple desire to push the envelope. Nigell didn’t wait for the Apple Watch, he developed his own in his garage. The same way Steve Jobs didn’t wait for IBM to develop a personal computer, he made his own in his garage. What better way to define us as a people than those not satisfied by the status quo? Those who braved the west, put men in the moon, cured diseases, and challenged every concept of stagnation. Innovation is the fabric of our society.

Much has been said about America’s continued motion towards outsourcing. Some go as far as saying that all hope is lost, and that the USA is deemed to a lesser role in history as a country of customers. These critics claim that manufacturing in America is prohibitively expensive and regulated. Some empirical evidence tends to favor these claims – it seems that more things everyday are made somewhere else.

A few weeks ago I wrote the post Made in USA: So What?! to describe a few of the reasons why Creative Electron manufactures x-ray machines in USA. This weekend we met with similar minded inventors and entrepreneurs committed to reclaiming America’s leadership in manufacturing. Needless to say the conversations were more about “how can we make this better” then “how can we cut 2 cents in the manufacturing cost of this unit”.  It was comforting to realize we’re not alone.

The trip to the Maker Faire renewed my hope in the American experiment – a place where innovation and ingenuity meet to create sustainable economies.

10 Basic Principles of X-Ray Inspection

TITANN: Rethink X-Ray Sample Manipulation


The determination of where the sample is located inside the x-ray chamber is critical to automated applications where several sample locations are inspected continuously and without operator intervention. The ability to go to the same location in the stage reliably and accurately is highly desirable. The state of the art in sample manipulation for x-ray inspections relies on the use of step motors connected to actuators that move a stage inside the x-ray chamber. The main problem with the use of step motors is that a number of steps is sent to motor so it can move, but there is no certainty the motor shaft turned the correct amount of times. Thus it is impossible to determine by how much the sample moved. Modern manipulation systems utilize encoders connected to the shaft of the step motor to count the number of turns of the motor. This feedback method improves the repeatability of the system and reduces the overall error. However, it is still prone to deviations between the number of turns of the motor and the actual movement of the sample. Another major shortcoming of this tracking method is that the error is cumulative. As the system is used the motion error compounds. As a result, these systems need to be regularly calibrated.

The TruView Infrared Tracking with Artificial Neural Networks (TITANN) is a patent pending technology that utilizes an optical target to locate the stage inside the x-ray chamber. These targets are infrared LEDs used to minimize noise in the image caused by visible light. By tracking the location of the infrared LED, the TruView software can determine the location of the stage/sample within 500um without the need for calibration. Better resolutions have been achieved for applications that require better sample control, including computed tomography (CT), laminography, and tomosynthesis.

We’ve also designed a custom infrared camera to track the location of the infrared LED on the stage. This megapixel camera is specially suited to operate inside the x-ray chamber.

TITANN-IR-Camera-sm

Artificial neural networks are ideal for repetitive applications – thus a perfect fit for an x-ray sample tracking control. The artificial neural networks utilized in TITANN greatly reduce system errors and optimize travel of the stage. The custom artificial neural network algorithms in TITANN keep track of the location errors at each stage movement and automatically adjust the control system to the motors to minimize the distance between desired and achieved location.

The TITANN technology is currently available on a selected number of TruView inspection systems. Contact us today for more information.

Made in USA: So What?!



A few weeks ago I had lunch with one of our competitors. He and I have an amicable relationship, and we get together occasionally. I share this with you because that meeting motivated me to write this post. During lunch he bragged how his Chinese-made cabinets are at least 30% cheaper than our USA made ones (he swears these savings already account for all logistics issues). He went further to brag about his software team in India, and the kind of skill set he can hire for $20k per year. Finally, he was proud that his US based team was mostly sales and marketing with a few people “operating screwdrivers”.

I don’t have anything against outsourcing to China, India, or any other country. I enjoy as much as anyone else buying $0.99 Hot Wheels cars at Walmart for my kids. That’s not the point. I run a high-tech company. Creative Electron, the company I started in my garage in 2008, develops and manufacturers x-ray inspection systems. As the company grew over the years, we had plenty of opportunities to outsource. We didn’t.

CEI-Team

Creative Electron team in one of our production lines in San Marcos, CA – 2014

Instead, we developed a business model around the core belief that made in USA is the right thing to do. Part of this strategy is gratitude to a country that gave me a lot. I moved to the USA in 1998 to work for the Department of Energy, at a place called Fermi National Accelerator Laboratory (Fermilab). It was my first job after college, so I started as an entry-level engineer. I went to back to school nights and weekends to get a MS, PhD, and MBA while working full time at Fermilab. In a few years I was promoted to Department Head, leading an incredible team of scientists, engineers, and technicians in the development of complex electronic systems for nuclear and high-energy physics research. This country is one of the very few places in the world where hard work and perseverance are proportionally rewarded.

After almost a decade at Fermilab, it was time to move on. The entrepreneurial bug called me to San Diego to start Creative Electron. Our first customers were the Department of Defense and the Department of Homeland Security. Together with other US government agencies that joined us later on, funding was secured for the development of an incredible product line. We are very proud of the services and products we are able to deliver to these organizations.

But gratitude is part of the reason we still make our x-ray machines in California. It still makes a lot of business sense to make things in USA. Forget about the 30, 40, or 60% savings people talk about. Innovation is priceless!

Here are some other important reasons to keep manufacturing in America:

1. Quality Control: This one is easy. It is much easier to keep an eye on your manufacturing line when it’s a few feet from your office instead of thousands of miles away. If something goes wrong you can address it immediately. It also helps a lot if you don’t need to wait months before getting a new batch of parts.

2. Customer Service Model: From the inception of the company I’ve been a believer that we should not have a customer service department. Instead, we have a customer support manager who is also our director of engineering. He receives support requests and routes them to one of our developers. Yes, that makes hiring developers a bit more challenging, because not only do they have to be awesome technically, but they also need to be awesome with customers. Having customers talking to developers directly allows us to get things fixed fast – without any bureaucratic red tape. The added bonus is that developers think twice before releasing product that might bite them later.

3. Innovation Speed: We are the underdogs in the x-ray inspection market. We don’t have a huge marketing budget or an army of salespeople pushing our products. Instead, we do spend every penny available in innovation. The fact we can change things fast – and learn from our mistakes fast – has allowed us to quickly improve our product line. We are in a constant dialogue with our customers, both big and small, to understand their challenges today and tomorrow. This focus on product performance for ultimate customer satisfaction has landed us major worldwide accounts.

A lot has been said about outsourcing, offshoring, and reshoring. You know what is best for your company – Made in USA is what works for us.

 

LED Assembly: How Excessive Voiding Costs You Money


One of largest obstacles to the widespread utilization of high brightness light emitting diodes (LED) for general illumination is thermal management. Localized heat generation is characteristic of the semiconductors utilized in these devices. For maximum lumen output, color consistency and device lifetime, this heat must be removed efficiently to allow the LED junction temperature (TJ) to remain stable. Maintaining a stable junction temperature over long periods of operation is the main goal of LED thermal management.

“You can’t manage what you don’t measure: Each 1% increase in void area can decrease the lifespan of an LED by up to 2,000 hours”

The rate at which an LED module will age is highly dependent on the temperature at the p-n junction and will accelerate over time. As a result, service life values are only valid provided that certain p-n junction temperatures (Tj) are not exceeded. Service life values are statistical values determined during test runs undertaken by LED manufacturers and do not reflect the precise behavior of individual LEDs.

The same applies to LED brightness values. The heat generated at the p-n junction impairs the efficiency of the light generation process and results in a measurable drop in brightness.

Case Study

To better illustrate the economics of LED die attach voiding, we analyzed a real life scenario. One of our customers is a large contract manufacturer new to the LED luminaires market. They offer two warranty options to their customers: a standard 38,000-hour warranty for free or an extended 50,000-hour warranty for extra cost. It is understood that a single LED failure results in a luminaire fail.

For this analysis we will assume the following pricing model:

–       Price of a single luminaire: $100

–       Price of 50,000-hour extended warranty: $20

–       Production and distribution costs: $35

–       Warranty cost: $5

The pricing model is based on the expectation that within the standard warranty period the company will receive up to 5% in returns, and up to 20% in returns within the extended warranty period. This LED manufacturer wanted to better understand if the amount allocated to warranty costs was enough. As an entrant in the LED market they understand the sensitivity of price competitiveness. They can currently fabricate LED luminaires at a reasonable profit margin, but fear that these margins will be destroyed by return of product within warranty.

Figure 1 – a) Photo of LED assembled onto substrate, b) x-ray inspection image of LED, c) x-ray inspection image with identified and measured voids using TruView 5 software, d) 3D rendering of die attach voids

100% X-Ray Inspection

The first step in this research was to understand the quality parameters of the customer’s production line. The need to set a benchmark is critical in this analysis so that we can understand what is working and what needs to be improved. The key metric we measured was the void area between the LED die and the substrate. We selected void area as a key metric because it can be measured in a non-destructive way by using an x-ray inspection system. Furthermore, the size and shape of void, combined with its location in the luminaire, provided us with important insight on the type of manufacturing issue we may be dealing with.

The Experiment

For this analysis we inspected a total of 1,000 LEDs and measured the die attach voiding of each of these devices. To accomplish this task we utilized a TruView 200 X-Ray inspection system, as seen in Figure 4. This is an x-ray inspection system capable of collecting the data and processing the void measurements automatically. The automated process was paramount to the processing of the daunting task of inspecting 1,000 LEDs.

Findings

The results of this analysis showed that this customer far underestimated the expected cost of return-products. Not only the pricing model utilized by the company had a deficit within the standard warranty; it had an even larger deficit within the extended warranty period. In consequence, the company had to temporarily change its pricing structure to compensate for product shipped with the deficient manufacturing process. Furthermore, a complete overhaul of the manufacturing process was done to bring it to tighter standards. The void area is now utilized as the key metric to measure process control quality. The TruView 200 X-Ray is used daily to measure the void of sample luminaires. Current data shows that the mean void area dropped to 35% with a standard deviation of 4.5. Thus, they were able to reduce the pricing for their luminaries. This reduction greatly increased their competitiveness in the market.

Creative Electron Granted Patent for Long Lasting X-Ray Tube


The technology is called APOLLO, and the patent is titled “Long-Lasting Pulseable Compact X-Ray Tube with Optically Illuminated Photocathode”. As you can probably figure out from the title, APOLLO does not rely on a heated filament to generate the electrons needed to make x-rays. Instead, APOLLO uses a special laser to shine a region of the cathode to create free electrons. The material you need to deposit on the cathode can be ytterbium (Yb), gallane-arsenide (Ga-As), cesium-antimony (Cs-Sb), or any variation of all these and other materials. We use a fiber optic to bring the laser into the vacuum-sealed tube, which makes it easy to focus on the cathode target. Some of the things that APOLLO enables us to do is to build an x-ray tube that can produce multiple x-ray beams, to change the focus of the x-ray beam as needed, and to pulse the x-ray beam as much and as fast as needed. And what’s going to make our customers very happy is that no heated filament means there are no parts to break inside the tube. In other words: we can make an x-ray tube that lasts for generations!

PLEX2sm

Why is APOLLO a breakthrough? The general idea behind the construction of an x-ray tube has not changed significantly in the last 100 years: an electron source is placed in an electric field that accelerates electrons towards a target (anode). If the electrons have enough energy, they will generate x-rays when they hit the target. Commercial x-ray tubes utilize a heated filament – which has a limited lifespan – as the electron source. This heated filament is not much different from the filament in the old light bulbs (remember them?). Refurbishing the filament in an x-ray tube is a very expensive process. Other than cost, other major limitations of the heated filament technology are the creation of pulsed x-rays or the changing of the focus of the electron beam. Both properties are highly desirable in a number of scientific and industrial applications.

APOLLO will change how x-ray tubes are made! For more information do not hesitate to contact us.

When Counterfeit Components Explode


When discussing the issue of counterfeit electronic components, we often rely on results from incoming inspections or results from failed systems upon deployment. We seldom have the opportunity to see the counterfeit component fail. One of our customers, a large military original equipment manufacturer (OEM) that shall remain nameless, recently sent us this case study. They can’t publish it, but we can.
What you see in this incredible video is an electrolytic capacitor exploding a few moments after power up. This video was captured after some of these boards failed during burn-in. For this reason one of their engineers decided to document the event by filming the explosion.

So how could they determine this was not some other issue, and that indeed it was a counterfeit problem? First, this was not the first time they made this board, which rules out a design defect. Second, they were able to correlate the explosion problem to a batch of capacitors they bought from an independent distributor (ID). It was the first (and likely the last) time the OEM bought parts from this ID. Third, they were able to compare the counterfeit capacitors with good capacitors previously used in this design.

Visual inspection

The following photo shows the electrolytic capacitor in question. A careful visual inspection of 100% of the parts in the lot in question did not present any inconsistencies. A further comparison to the good parts used previously also did not show any issues. Based on this data they were not able to determine the legitimacy of this component using visual inspection.

TruView X-ray inspection

The next step taken by the OEM was to perform a 100% x-ray inspection using their TruView 280 x-ray inspection system. Here are some of the images they’ve shared with us. On the left you can see the reference component capacitor – a component from the previous known good lot they bought from a large authorized distributor. The x-ray image on the right shows a capacitor from the new lot they bought from the ID. There are significant structural differences between the two parts.

They also found solder residue on the leads of the counterfeit capacitors. The following high magnification images show the location of the solder residue. This residue was not detected during the visual inspection because it is too close to package of the capacitor, and in some instances inside the plastic package.

Why were they lucky?

The cost of repairing the boards that failed during burn in is minimal when compared to the cost of replacing the boards in the field. Unfortunately, the cost of replacing deployed boards usually comes with other associated costs. These costs go beyond monetary liability – they damage reputation and can cost lives. Those can lead to the demise of an otherwise reputable corporation.

To better illustrate this point, the following chart shows data collected by the U.S. Department of Commerce’ Counterfeit Electronics Survey. Published in August of 2009, the report shows that most companies learn of counterfeit parts when they return from the field as defective. As we already established, that is the most costly way to find about a counterfeit component.

Only expensive parts are counterfeited

This OEM has a good quality inspection program and counterfeit mitigation strategy. However, it is incomplete. They have a policy of inspecting IC’s only – thus neglecting the risk of counterfeit passive components. Needless to say they’ve learned a very expensive lesson. The explosion of these capacitors damaged several parts around it. Henceforth passive components have been added to their counterfeit mitigation program.

The following data shows the number of counterfeit incidents as a function of the price of the component. Components between $0.10 and $500 are the most commonly counterfeited. It is not a surprise that the electrolytic capacitors reviewed in this post are well inside this range.

counterfeit-incidents-by-product-resale-value

Buying from good vendors

Some companies erroneously believe that a counterfeit mitigation program can be limited to buying from a selected number of suppliers. This OEM only buys components from qualified companies in their approved vendors list (AVL). That works until they really need a component that leads the OEM to have to buy it from whoever has a part to sell. It’s either that or missing a delivery deadline. That’s exactly what happened here. It is very challenging to keep the AVL discipline when the production line is stopped and parts are desperately needed. The following data shows the probability of buying a counterfeit component from different source in the supply chain.

TruView Cube: the Mighty X-Ray System

by Bill Cardoso in Creative Electron Comments: 0

We are very excited to share with you that the TruView X-Ray inspection family of products has a new member: the TruView Cube. Over the past few years we noticed that quality inspectors, researchers, and engineers looking for a benchtop x-ray machine were limited to entry-level systems that produced entry-level images. That means limited features and limited image quality. Here’s our message to those looking for great image quality in a small cabinet: Look no further, we heard your call!

The TruView Cube, in its 16″x16″x16″ profile, sits comfortably in any laboratory bench. I actually have one in my office (the TruView Cube fits nicely between the printer and my Nespresso!). The idea is that you no longer have to compromise price, quality, and size. If you need to inspect samples smaller than 6″x6″, why would you have to buy a system that takes a whole room to get good quality images? The TruView Cube fills a huge gap for technical people who have been debating for years if they should or should not buy an x-ray system. We made that decision easy for you to make in the form of a Cube!

As usual, contact us to learn more about the TruView Cube. Since an x-ray picture is worth a thousand words, I’ll leave you with a few shots from the TruView Cube!

Magnification and Field of View: X-Ray Inspection Explained


When talking about x-ray inspection, we have noticed over the years that magnification and field of view (FOV) are characteristics not well understood. To set the record straight, in this post we will describe in detail what each one of these parameters mean. The following figure shows a simplified diagram of an x-ray tube. Note that the modern tubes used in our systems are far more complex, but this diagram is very useful to illustrate magnification and FOV. The x-ray tube is the device inside the x-ray source that generates the x-rays that are used to project an image onto the x-ray sensor. The electron beam generated by the cathode is rapidly accelerated against the anode. Upon colliding with the anode, a beam of x-rays is generated.

x-ray-tube

Schematic representation of an x-ray tube

The random nature of the collision of the electron beam on the anode target creates an x-ray beam that is cone-shaped. As the x-ray beam moves farther from the anode target, the diameter of the beam increases proportionally. The angle of the x-ray cone beam, α, is determined by the angle of the anode target. The following figure shows the FOV at different distances from the source. This measurement is called source to object distance (SOD). It is important to note that the SOD is not measured from x-ray window to the object. Instead, the measurement starts from the target inside the tube to the object. X-ray source manufacturers give us that distance, so we can add it to the distance from the top of the source to the object.

field-of-view-magnification-x-ray-inspection

Change in field of view as a function of the source to object distance

What the previous image shows is that the diameter of the x-ray beam increases as it moves away from the source. For example, at 2” from the source, the diameter of the x-ray beam is 1.4”. To better illustrate this discussion, let us use the TruView Prime x-ray inspection system as an example. The minimum distance between the x-ray source and the x-ray camera in the TruView Prime is 6”. This measurement is called the SID – source to imager (x-ray camera) distance. The SID was designed to accommodate TruView Prime’s large 3”x4” high definition flat panel x-ray camera. That means that we would see vignetting of the image if we placed the camera closer to the source. The following image shows an example of vignette – an x-ray image when the camera is too close to the source. The dark corners in the image represent the regions where the x-ray beam is not shining.

x-ray-image-vignette

X-ray image with vignette

Now that we have a better idea of how to calculate the FOV based on the distance to the x-ray source and the angle of the x-ray beam, the next step is to connect it with the concept of magnification. We will use the TruView Prime as an example again. In the TruView Prime, the camera, or x-ray sensor, can move up and down to change the distance between the camera and the sample, as seen in the following figure.

x-ray-inspection-parameters

Field of view, magnification, source to object distance, object to imager distance: critical parameters in x-ray inspection

The magnification, M, of the system is given by:

x-ray-inspection-magnification-inspection-equation

In the example shown in the previous figure, the magnification of the system is 2:

x-ray-inspection-magnification-example-equation

That means that within the boundaries of the 3”x4” x-ray sensor in the TruView Prime, the sample image will be magnified by 2X. Thus a 100um2 feature in the sample will be projected in a 200um2 area of the x-ray sensor.

We hope this post was able to clarify some of the topics related to x-ray inspection. As usual, we’d love to hear your feedback!

 

Apple iPhone 5 Teardown: X-Ray Inspection Version

by Griffin Lemaster in Applications, Creative Electron Comments: 0

Thanks to all the feedback we received from our previous post. Popular demand asked us to x-ray an Apple iPhone. The plan is to take a look at an iPhone 5 this week, and compare it to an iPhone 5S later. I think you’ll be surprised how much changed between these two smartphones.

iPhone5-teardown-xray-inspection

As usual, here are some interesting parts of the iPhone 5.

The audio jack also moved from the top of the iPhone to the bottom. In this x-ray image you can also see one of the 3 microphones in the unit.

iPhone5-teardown-xray-inspection-4

The other side of the Lightning connector is not as busy. Other than the antenna connection, the area is open as an acoustic channel for the loudspeaker.

Image Intensifier or Flat Panel Detector?


The question of what’s better – a digital Flat Panel Detector (FPD) or an analog Image Intensifier (II) – is a good one and depends on the actual usage of the system. There are multiple factors to consider when designing an x-ray inspection system. Image Intensifiers are old school technology from the late 1950’s and were the standard (only option other than film) up until some where around 2003- 2004. The technology is a vacuum tube (electron multiplier) with input and output windows that are phosphor coated to convert photons/electrons into visible light.

This same technology is used in a smaller scale for night vision. The main advantage of this technology when used in an x-ray inspection system is the ability to image down to 5 or 10kV. There were other advantages to II based systems over FPD; one is the speed. Image Intensifier based systems operate or produce images at 30 FPS (frame per second) – this is considered real-time. Two is gain, 15000 to 36000 gain makes the Image Intensifiers very efficient at converting electron/photons to visible light at low x-ray or light levels. This is key if you are imaging paper or very light density samples but no so important for most Non Destructive Testing or SMT/PCB applications. Third is the easy ability to create magnification that is not pixel based, the magnification can be achieved in the Image Intensifier by reducing the input window size electronically. A four-inch input on a 2/4 Image Intensifier can be reduced to 2 inches and double the inherent magnification above and beyond the physical geometrical magnification. This technique also has disadvantages because as you reduce the input size you also reduce the Photon statistics resulting in a need to increase kV or mA to offset the loss of incoming photons / electrons / light.

Now for the down side of Image Intensifier, the vacuum tube is convex at the input window, there is always an inherent pin cushioning effect on the resulting image and makes measurements difficult without doing some type of correction algorithms. All output windows of Image Intensifier’s are somewhere around 25mm regardless of the input window size, the input can be electronically manipulated but the output remains the somewhere around the same 25mm. By using lenses and cameras that are focused on the output window we can transfer the image to a monitor or computer. Again this is an area that allows us to increase magnification by using a variable lens system ( 7X zoom is typical) or choosing a lens camera combination to maximize magnification. The problems arise from the mechanical camera lensing combinations, the coupling of the camera to the lens and the combination of the two to the output window results in light loss and degradation of the image.

In the old days we used CCD cameras that needed to be run through an A/D converter before the computer processing, today we would use a mega pixel digital camera and avoid the A/D conversion. The camera/lens portion of this set up is very susceptible to dust and vibration and can easily become unfocused and require frequent cleaning and or adjustment. Then we get to the analog portion of the Image Intensifier. No matter what mega digital camera and lens combination you attach to the Image Intensifier it is always going to be 256 levels of grayscale. In other words, you get 256 shades of gray. This was fine for old school visual inspection but is really under utilizing the computing power of the newest image analysis software packages. Then there is the size factor for the standard electronics inspection Image Intensifier, the weight is somewhere around 20 pounds and the physical size is around 18 inches in length depending on the camera combination, the use of the Image Intensifier will require a larger cabinet/x-ray system regardless of the sample size. Then there is the issue of moving the Image Intensifier on a stage, tilting the weight becomes much more difficult and also exposes the camera/lens combination to vibrations which lead to an out of focus condition and reduced resolution. Image Intensifiers (outside of the night vision ones) operate at 24000 volts DC, so there is a chance of the vibrations to contribute to the failure of the HV power supply that is physically attached in some cases to the Image Intensifier.

Flat Panel Detectors became commercially available somewhere around 2000-2001 when computing power became available and more affordable. This availability was also enabled by considerable improvements to the semiconductor fabrication techniques needed to build large tiles of sensors. FPD uses a couple of methods to convert the scintillating layer of visible light to electrical signals that are then converted to a image that can be displayed and analyzed with the latest software/computer advances. The two most prevalent technologies are photodiodes and CMOS. There are a couple other technologies available but they are very cost prohibitive when building general electronics inspection systems.

The advantages of FPD are the size of the physical package, the flat input window and the grayscale or spacial latitude (4096 minimum grayscale vs. 256). The abundance of grayscale has resulted in computer analysis software algorithms that can detect a single grayscale variance thereby producing test results that are impossible to achieve through visual analysis (the human eye can not really detect grayscale past 256 shades). Furthermore, the resultant flat image requires no corrections for accurate image analysis and measurement. The signals produced are also digital, so there is no loss of the signal A/D conversion or image degradation because of lensing or camera configurations.

Larger FPD’s can also be economically produced by connecting multiple photodiodes or CMOS panels together as opposed to large area detectors made from single sheets of amorphous silicon. There are no moving parts (focus – zoom – iris) on a FPD and the requirements to move (z-axis / tilt) are fairly simple as well as no dust or vibration concerns. FPD detectors had only two disadvantages or concerns when compared to Image Intensifiers. One is the speed; typically FPD’s will capture images at speeds of less than 30 FPS although the speeds are increasing as the cost for the increased speed is decreasing. Modern FPDs used in Creative Electron TruView X-Ray Inspection systems come standard with 30 FPS speeds. The second disadvantage is the FPD’s need for high flux or high photon statics. Typically a FPD will require a higher kV \ mA combination (wattage) to achieve a usable x-ray image vs. an image intensified system. However recent advances in FPD technology has greatly bridged this gap.

The original FPD’s were very expensive and painfully slow when compared to Image Intensifier/ camera systems but the trend has been that of larger FOV / Panel sizes running at faster speeds (30 FPS) while at the same time bring the costs in line with Image Intensified systems. The use of FPD’s is pretty much the standard in industrial cabinet x-ray systems today.

There were only a few reasons that an Image Intensifier based systems would excel over a FPD based system, that being a low density sample requiring very low penetration (paper) or speed/FPS and the speed issue is quickly becoming a non-issue. Please let us know what you think about this post by including your feedback in our comments area.

What is X-Ray Inspection Resolution?


Here are a few things to think about before you ask that question.

During my years in the x-ray world I have been asked that question thousands of times and I provide the industry standard answer of some number in microns or how many line pairs per mm.  Both methods are totally valid and industry acceptable measurements of x-ray system resolution.

The problem I have always had with this answer is this, both are measurement results that are exacted under the most controlled circumstances imaginable.  An individual that has an in-depth understanding of x-ray imaging techniques performs these measurements: penetration, power and magnification are optimized to perfection.  This individual in most cases is also an expert on the imaging software suite in question.  On top of that the gauges used for taking these measurements are made of very low-density materials and have their own inherent limitations, which limit the use of higher kV and mA settings.

The major reason both of these measurements are not the end all is both are dependent upon magnification, you will always see the “at maximum magnification” behind the Line Pair Per mm (lp/mm) and overall system measurement results. The reason for this is without the magnification it would be impossible to see the extremely small details of the test gauge on the system monitor.

The second reason these two measurements can be deceiving is power or really the lack of power needed to image these two extremely low-density gauges. X-ray tubes with small spot sizes perform best at low power, a 5 micron x-ray tube will provide the best images at 4 or five watts of total power, increase the total wattage to image denser samples and the iso watt control of the x-ray tube will open up the spot size to dissipate the heat on the anode as total power to the x-ray tube is increased. When the spot size is enlarged your resolution has just been decreased from that starting number of say 60 lp/mm to say 20 lp/mm.

If your typical sample has a density above the density of the lp/mm gauge or requires a larger field of view with magnification less than system maximum you can’t assume that you are going to get the maximum resolution results during daily use on your production floor.

Line pair gauge used to measured the resolution of x-ray inspection systems

I am sure you are getting the idea here … these numbers are not real world numbers and should only be used as a starting point.

So… you’re thinking “ how do I chose an x-ray vendor or x-ray system manufacturer if I don’t use the industry standard measurements as the deciding factor?

The answer is simple; send your typical samples to the x-ray system manufacturer to get a demo. By using your real life samples the x-ray system will be adjusted out of the maximum resolution range into a more realistic operating range for the power required and magnification to image your samples. By using your typical samples you will get to see what the true resolution of the x-ray system will be on your production floor, which is really the only number you care about anyway.

For more information please don’t hesitate to contact us. We’d be happy to prepare a complete report with the x-ray inspection images of your samples.
