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?
