Seeing through circuit boards

I’m resolving some manufacturing challenges in the new chumby design and had the opportunity to use an X-ray board inspection tool. This tool is what you want to use if, for example, you wanted to reverse engineer a circuit board with buried or hidden traces. It also lets you see through the packages and inspect the quality of the wirebonds. This particular system has a feature that let you rotate the board as you inspected it so you can look at it at an angle-which is actually really cool to see live, it’s sort of like flying through the circuit board. I wish I had a video of it but I didn’t bring my camera into the shop today.

Anyways, I thought those who have never seen this capability before would find the following pictures interesting and perhaps thought provoking.
