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

If the tab is Sn plated, you can solder to it as long as your iron has enough power (watts). If you continue to have trouble then it probably isn't Sn plated.

Hello all. We have been having some problems soldering to what we believe is a nickel plated spring steel battery terminal to a PCB. We have tried scrapping , then tinning, dipping and still have problems. Are there any special fluxes or pre-treats t

I assume that you're talking about wanting to solder to metal tabs that are spot welded to the battery terminal. These tabs are not meant to be soldered. The metal was special selected for welding. In the old days, you could buy plumbing flux at th

Things don't disappear completely. If something caused nickel corrosion, the nickel corrosion by-product would be in place of the nickel. Is it possible that ... There never was any nickel? We know that the nickel will diffuse into the copper. Th

I have a pin and sleeve assembly that utilizes a fusible link type of solder, Bi, Cd, Pb and Sn alloy. The pin is gold plated, the sleeve is copper alloy 725. I have had sporadic success with wetting of the sleeve during the reflow process. To improv

We agree with Russ that you're talking palladium instead of platinum. Your wetting problem likely is not the Pd-Ag surface layers, but the underlying metal or nickel to which you need to wet. Either a base metal is: * Contaminated and poorly wettabl

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

Hi, We are placing (+) & (-) terminals in SMT. We have just changed the plating of them: from Nickel to Tin (Sn). During the trial, we used the same reflow profile as before changing, and the solder seems different: a bit cold, with some solder paste

i want to know which type of solder paste and reflow profile can support the solder pad with nickel but not covered gold on the pcb.
