One of my customer asking me about my capability on soldering nickel strip onto the PCB pad. Given the size of the pad of 80 mil X 80 mil, and he want to ensure that we can pass 4.5kg peel force(solder wire Sn63/Pb37). Anybody with this experience ?

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

Hi Prem, We used to place millions of Nickel battery tabs using Cobar paste. We found it particularly aggressive. Just contact your local Cobar distributor and ask them for samples of their most aggressive fluxed paste. Kind regards, Rob.

Hi Robl, Thanks for your qucik reply!! , i understand if we use aggresive flux that we can impove solder wetting over nickel plate vs PCB pads & we need to solder through 12 zones reflow oven. Prem

Hi Prem, Yes, the flux in the Cobar paste helped with wetting and joint strength, as does reducing voids as there is more solder in the joint, as does cooling rate. Regarding peel test in KG, it depends on the pad size and volume of solder in the j

Hi Prem, Voiding has lots of causes, but boiling off flux to quickly really doesn't help, so maybe a more gentle profile. Also you do not need to print a solid block of paste, you can print a window pain style pad to help the flux escape. Also, th
