We are experiencing problems with a smartmedia connector during the reflow solder process. The connectors stay a little bended after the oven. In this case the middle leads are not solded, because they stay with no contact on the board. The conector

Expanding on a previous poster's comments ... Vapor Phase Soldering. A solder reflow technology that uses a heated solvent to melt the solder. Buried deep in the recesses of the SMTnet Library is �Terms & Definitions�. We started using vapor phas

I don't suggest using Pd/Ag or Ag/Pd terminated components unless you are forced to use them. You often see a line of demarcation that suggests a poorly wetted solder joint. I have had bad experiences with Pd/Ag terminated capacitors. Even when so

Pavel, We had exactly the same kind of problem with exactly the same type of component. Our components were well within their best before -date so it is not question of that. As we could not get it to work we changed to nickel barrier finish on the

I am being asked to perform the same evaluation now with a Au/Pd termination varistor. We currently use a Pb/Sn process with an RMA flux. The manufacturer of the device recommends going to a 2% silver paste. What is the intended advantage with 2%

Folk's, Been asked / told by my boss to look into our board prepping area for wave soldering and find another way of doing it. Thing's I'm looking at are: PCB Breakout - do you do it before or after wave Connector's that need to be pressed in due to
