<< Hey all.
How should one go about inspecting PGAs after wave soldering? I've checked
the archives, but can't find anything. I would imagine that you'd have to
use X-ray equipment, but are there specific angle to take shots from?
Thanks,

Hi Eric!
Most of the PGA's I've seen are ceramic, are yours? If they're ceramic, it's
gonna be pretty difficult to x-ray...that's where an ERSA scope would come in
handy. Most PGA's that I've done are socketed, and I've been lucky because
usually the sockets have openings where I would be able to see the pins on
the inside.
I've got an ERSA scope now, I'll find a board around here with a PGA on it
and put a picture up to show you what it can do...
