| What selective soldering products should I use for a low production rate, high-mix product line? I am looking to get rid of some hand soldering. I have seen exselect (selective soldering pot method), pillarhouse (small flow solder nozzle with robot

I have a product using high temperature solder to connect terminal pins to a PCB. The board is single sided copper, no plaiting. The solder is 95% tin 5 % silver. The flux is low activity rosin. The product is a subassembly. When the product is

Are there anyone who can give me the answer about solder ball problem? We have 12 layer PCB and double sided PCB. After one side reflow soldering We found lots of solder ball under the PCB. The solder ball was coming out from via hole. So when w

We have come across this where the operator was using thin gauge solder wire (more suited to fine pitch SMT soldering) to form large solder fillets (power connections or sheild cans). We found that the operator was feeding large amounts of solder wir

Bill This drives solder suppliers nuts, because it's not analytic: Dross inclusion testing can be conducted on the base solder in the solder pot and the virgin solder. Conduct this test by heating a sample of solder, contained in a clear beaker,

Peter: Please explain: * You say, "The cooling phase is important to perform the strength of the solder joint." [We agree that fast cooling rates produce fine grain in solder and that fine grained solder connections are stronger than coarse grained.

You say, "using Eutectic Solder." * There are lots of eutectic solders. * When melted, a eutectic solder goes directly from a solid to liquid phase with no pasty phase. Do you mean 63/37 tin lead solder? If so, probably your assembly won't be RoHS

we do that and there's a variation on the solder temp. sometimes around 10 degrees, we have 2 solder pallets that are run in intervals of roughly 3 1/2 minutes a part (the time that take the operator to put all 3 terminals in a 42 pcbs per board, and

To be honest, I have never had success wave soldering or reflow soldering batteries, regardless of their intended use. If you're going to continue a manual operation to solder one pin, I'd suggest that you just solder the entire component in by ha
