A couple of questions to establish a baseline for when the check writers start asking questions........ How many of you have vision systems on site for BGA inspection? If you don't have it, do you do 100% X-ray, or did you just nail down the proces

Ernie: I'm guessing your question is a bit far a field for us. I�d guess that 70% of us are no-clean with the remainder focusing almost exclusively on cleaning printed circuit boards. So rather than limiting yourself with us, also consider forums a
