No we have a battery spring that is soldered directly to a PCB (standard tin plated copper PCB). The Battery spring supplier (and I have no confirmation he makes them or buys them) claims they are tin plated. When trying to solder to them it is very

Hola Grayboard, I've had the same situation with these components, I changed the stencil apertures a little bit and use a stepped stencil (5-6mil), after some trials we were able to get decent yields, but we still had some failures, what we discover

Could be. I am making overprint to achieve proper amount of solder paste inside hole. Now I am trying to reduce maximum overprint and compensate it with step - up stencil. This could reduce effect that some particles of solder paste are not gathering

I am curious to know how others are providing N2 for their lead free selective soldering process. If you are utilizing a nitrogen generator, is it a PSA type or Membrane type? I am trying to get a handle on nitrogen purity and what purity is necessar

I am working on soldering an Large LGA module to a PCB and am having some issues with opens due to variation in the board flatness. I have tried adding more paste but get shorts and excess flux as I get above a 7 mil stencil. I have tried adding sol

I've got good news and bad news: GOOD: I love Ag2 solder it's the best, most well behaved, reliable, couldn't ask for a better general purpose solder. BAD: It's leaded. I'd be concerned about embrittlement issues when soldering to gold that was 10 t
