Hi
We are trying to solder a a contact whose base material is stainless steel, this is then nickel striked with a gold plating of upto 3 microns. We are trying to hand solder this to a standard 1.6 FR4 PCB with a HASL finish. We are seeing problems such as non-wetting ,dewetting and solder peel-back. We have tryed tinning these contacts, but it does not seem to have made much difference. Any advice would be much appreciated.
