Assuming you are talking about solderable surfaces: People specify various materials to protect the solderability of the pads on the board. Gold, actually, Electroless Nickel - Immersion Gold [ENIG], is popular. * Board fabricators like it because

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.

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

Why soldering issues? I'd guess the nickel is corroded. It is very difficult to solder to oxidized nickel. Your SAC305 would get kicked all the way down the conveyor by nickel oxide. A lack of Ni-Sn-IMC formation will confirm this dewetting . What's

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

Hi Sachin, thanks for your feedback. According to our supplier, surface plating is electrolytic gold over Nickel(not ENIG), but I think that is a still improper thickness for Au. (according to 3rd Working Draft from September 2008 of IPC 2221B "0.4

Thanks for your answer. For your question, this problem first happend on board with components so,we tested a board without components. As you said(only your case),if i inform our supplier, i will not get any answer from him and this will be very

Tin is pretty standard. I would doubt your leads are only Nickel plated as Nickel will oxidize very quickly.

Randy's correct. If you were soldering to nickel with WS609, you would be complaining about non-wetting, not lumpy solder flow.

We are having solder fillet finish issue. The solder looks like rough solder on the connector leads .The plating of the leads is Nickel (99.9% purity) and the PCB plating is imersion gold. I have tried fine tuning my reflow profiles an have used N2 i
