Hi all, I work for a service company who do SMT repairs for a Blue Chip. The JEDEC standard doesn't seem to mention how long (if at all) you should bake a planar after placing a new BGA (after field failure). Any ideas? Thanks in advance. regards Joh

JEDEC defines packaging, matrix trays, tape and reel, and like whatnot. You need to be searching ANSI and IPC. Find these documents: * ANSI/J-STD-020, Moisture/Reflow Sensitivity Classification for Plastic Integrated Circuit Surface Mount Devices *

SN100C is designed not to corrode your pot, and can be used on standard solderpots (after a proper clean out), whereas SACX is still corrosive and if the coating is compromised then could cause problems. Get it in writing from the supplier that the

much prefer using percentage instead of fixed overage. Example.... A run needs 100,000 parts, (1% shrink is 1000 parts!) you want to only issue 60 over? I recommend 2% for popcorn and exact for retrievable/ identifiable parts like sticks and trays

Yes indeed you make great point as well, we also run low volume production as well as some high running stuff, seems as though some type of combo nwould be best, maybe something like 20 pieces over or 2% wichever is greater maybe? Russ

Depending on what kinds of machines you run and feeder style, self adhering leaders work well to minimize the need for a long leader. We use them on every reel. We can generally load most feeders with only waste of about 4 parts by use of leaders (
