Dan,
This is not an answer to your repair question, but an inquiry of my
own. We are about to assemble some boards using TBGA's and was
wondering if these packages require pre-baking as do PQFP's to remove
moisture. In reading about TBGA technology, I find no mention of
pre-baking or moisture sensitivity ratings. Please advise.
Thank you in advance,

we are currently building some 18" by 20" product
with up to 4 500+ I/O TBGA's......The production
process is ok....but we have some difficulty
during repair....Preheat profile control is a
critical parameter...does anyone have experience
with TBGA repair on big boards? What repair
platform should I investigate?
thanks
dan
