Adding to Dave's comments, suppliers of selective soldering machines include Air Vac and Wenesco. I've used both, to solder and de-solder larger thru hole parts, such as connectors and large IC's. They are best suited to lower volume applications, an

I have a question about solder masking via's in a BGA pattern, and want to see if I'm thinking correctly about this. This problem is kind of along the same line as Carol's problem earlier. I think it's a bad idea to leave the via's free from solder

Good afternoon all, I am looking for help from you folks to find a place that can do metalurgical analysis on components and contamination. We are an OEM and just recently received back from the customer several units that failed in the field after

I found some machine manufacturers put convection nozzles in line parallel with each other instead of staggering them so you get a nice parallel line up the board where there is no flux be it no residue alcohol or VOC Free. The best I could find was

Your customer's question is reasonable. Soldering to nickel is not always a walk on the beach [can of corn, or whatever]. This issue is flux not solder. Your Sn63 will have plenty of strength, providing the solder connection is well formed. You s

We have been experiencing intermittent problems with the solder masking bubbling up from the bottom side of the board, after wave soldering. Our board fabricator claims that none of his other customers are experiencing this problem, and that it is pr

Thats the problem residual residue from HASL fluxes Lead free especially are worse.Very hygroscopic and out gass and produce dewetting as well over wave soldered boards especially. Leave iron on blown joint and will after several seconds fizz and pop
