Just to add my few cents, X-ray I'd s good thing to do if there is a gross problem (short or missing ball, or HoP) but it's pretty much useless if joints are cracked.
Dye&Pry is quick inexpensive but not always conclusive. We normally advise our customers to do it if they have several failed samples.
X-sectioning I'd still the most appropriate test to carry out.
Well be happy to help.

Curt,
As far as a test lab, I've had good success with Celestica in the past.
As far as the testing you need, if you are doing FA on a BGA, X-ray is nice to see if you have a problem, Dye & Pry is nice to help understand the location and scope of the problem, but you really need cross section analysis (SEM/EDX) to analyze the failure mechanism. Skipping the cross section will save you time now bust cost you much more time over the next month.
Pete
