It never ceases to amaze me how topical these - um - topics - are.  I just 
sent a box of boards out last nught to an x-ray shop.  (same boards I asked 
about earlier, this time with lead free BGAs).  We're getting strange results and 
assumed there's opens in the BGA.  I don't have a lot of confidence that the 
used a hot enough profile for a big board with many copper planes, so I'm 
expecting some non-wetting. 

Can I assume from this thread that they very well might give these boards a 
passing grade, yet we could still have opens?  The lab says they can do angle 
x-rays, we turned down another shop that said they do top-down only.

One of the suspected opens is in row 2.  What about a BGA scope for that 
one?
