Xrays go through aluminum quite well. I've xrayed BGAs with heat sinks that were well over an inch tall and they only made faint shadows. What material is the bottom of the PCB? And how are you going to bond to it?

Sounds like a good challenge. What is your interconnect bond method? Solder Paste, Pre-Form/Liquid Flux or Paste, Assuming your using solder. Reflow method?

I agree that Dage makes some excellent 3D (CAT) systems, but in our experience a high-resolution 2D system with tilt capability is usually better-suited for inspection of solder joints. Glenn Robertson Process Sciences

hello, can anybody help to compare SAM to x-ray methods with regard to inspection of semiconductor devices (smd LEDs, for instance)? Advantages and disadvantages of each method? Thank you!

Speaking from experience, my vote goes to Mirtec MV-3 or MV-7 with the 4 Megapixel camera setup. 2 Megapixel cams won't inspect that small, other than for presence Yestech also has machines that are suitable for this work. No company affiliations,

Have you checked out YESTech X-Ray systems? Their 2D X-ray systems to fit your requirements and they are usually at a very reasonable price point for what you get. Good Luck

Sounds like SPC data collection is turned on with post print alignment inspection. Needs to be changed to "NONE" http://www.dekhead.com
