Good Morning everyone. Per repeated suggestions I have been reading back issues of SMT and Circuits Assembly magazines. I have just read an article concerning selective wave soldering which I understand is to be used when active SMTcomponents are a

Adam- Mikie here. I too am placing 2 PBGA sockets on an assembly but they aren't mirror imaged. Thanks to the SMT Gods for that one. You say you added more paste to solve for open solder. Do you have x-ray? Were the alignments perfect? Also the part

I agree with EMC based on what you described, and they build good pallets along with a few others, a small word of caution is that pallets are bit expensive typically several hundred dollars or more each. So if you find that is the road you go, be s

Before this wave solder pallet salesman blather gets too far out-of-control, let�s stop for a minute. The three major approaches you have are: 1 SELECTIVE SOLDERING: Using: * Specialty wave soldering machine to solder specific areas of a board * P

Have you thought about wave solder contamination ? . We had a similar fault where glued chips were being shorted out due to "slivers" of solder dross being deposited onto the card . These dross slivers were being generated because the solder bath had

I go with DaveF's advice. You are probably curing the glue too fast. Another phenomenon that I have experienced was during glue cure and solder paste reflow simultaeously. A good reason to run a glue cure profile seperately from solder paste reflow
