Never experienced any problems with CCGA's either in production or
replacement. I did hundreds of these things with the SRT because of an
upgrade. It took almost six months for all the replacements at 24 per board
with 1200 columns. Only minor problem was with sorting out GSM placement
accuracy concerning the vision system.

Really had to watch column alignment though as you say. Other than that, no
problems. I guess, as I don't clearly remember, the force issue was resolved
as a function of machine programming but the parts were so heavy anyway, I
don't think it mad a difference as they just sunk into the paste and aligned
very well.

Interesting stuff, eh Gaby?
