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

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

There a number of studies like this published by component fabricators. Many can be found on the net. For instance: http://www.amd.com/us-en/assets/content_type/DownloadableAssets/Pb-free_Board-level_reliability_study.pdf

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

Could you direct me to a Standard or Study that has used this termination with 67/37 tin/lead solder please? I am looking for the recommended reflow temperature requirements and reliability issues for the completed product. We are receiving this type

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.

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

It sounds like the parts are not soldering properly [have poor solderability]. This probably due to corroded nickel underplate caused by: * Nickel that oxidized, while awaiting overplating * Poor quality tin overplate, allowing nickel to oxidize aft

have you tried a more agressive flux like water soluble to see if the problem goes away? Or can they be hand soldered with no problem? I am basically out of ideas other than a bad nickel or tin finish. The reflow profile didn't seem out of whack f
