In The Lab with Julia

In The Lab with Julia

Meet the team, go behind-the-scenes, and learn how we obsess about every detail of every product.

Meet Julia, our Sr. Failure Analysis Engineer (it’s like the CSI for tech). She finds root causes for issues so they don’t happen again. 

What does the X-ray Computed Tomography (CT) do?
It gives a 3D X-ray image that can show you the inner workings of your sample - a device, a pod, an adapter, or materials.

How does it work? 
It takes 2D X-ray images as it turns the sample around one full rotation. It uses these 2D scans from all angles to compute a 3D scan that can be sliced and diced to reveal any system, subcomponent or layer within the sample. 

Why is it important to use an X-ray CT?  
X-ray CT allows us to look at the inner workings in a non-destructive manner. This is important because you can see how something is functioning in-situ, meaning in its place, instead of just guessing based on how it was put together. If there is an issue, you can see it without taking the system apart. If something is in the wrong place you can find it there. Maybe most importantly, you can see hidden layers like solder joints on a circuit board, or metal contacts within a plastic housing. 

How does it impact a PAX product?
This gives us the ability to find and fix problems before a new product ever gets released to the field and to solve problems on another level. 

For example, we can see how the oil moves inside a pod, and we can figure out that a device got dropped by seeing the misaligned parts. By using this tool, we can pinpoint problems with micron-level precision and fix them faster and more effectively.

Finally, when do you use the X-ray CT?
In every part of the product life cycle: failure analysis during the NPI (New Product Introduction) process ensures quality of mass production components and assemblies, during reliability testing ensures longevity of the product, and root-cause analysis of customer device returns ensures our high quality standards are consistently maintained.
