Just wondering if there are any new and useful non-destructive ways of finding open connections or poor wets deep under area array packages. We've tried a number of different x-ray technologies, including tricks with angles, and scanned beam laminography, without much success. And those optical methods, like prisms or ErsaScope, are pretty good at seeing the outermost rows, but we may lack the talent or technique to be able to see much deeper. It would be nice to snake in some thin fibers, maybe a few to carry the light, and another one for the image, like a boroscope. Anybody got anything like that?
