Cool but just to reference 3D X-ray systems There are 3 types of systems: The 5Dx type system - this will generally not find co-planar cracks as it is slicing in 3 to 5 places horizontally depending on the set up, board bow etc. Then there are the new hi res 3D x-ray systems which are generally driven by an operator who knows that they are doing, I have (once) found a co-planar crack using these. Then there are the gazillion dollar amazing resolution 3D computer modeling systems which I was referring at the 4K set up charge. I am trying to get the details of where I had that done and will mail you when I find out.

Thanks for the various suggestions. We have had some experience with "3D XRay" systems in the past and will try it out on our solder ball joints. I will share the results with the net if we learn anything noteworthy.

I used this system 2 years ago up north of San Francisco I think, it cost about $4000 for the set up plus about the same for the shots, but the results were incredible, you can literally "fly" through the 3D Xray using the software. If needed I wil dig up th company and details of the people and send off line.

Crack? Opens? Unsoldered balls? I know that Micro-CT imaging can get down to sub-micron feature sizes in 3-D. Does that get you the detail you need?
