Hi Aj, Recommended Immersion gold thickness would be 3-5 Micro inches over 140 -200 micro inches of Nickel. Thicker Immersion gold than 5 micro inches can cause solder joint embrittlement. Gold readily dissolves in molten solder and will be present

Hi Dave, Yes that is correct. I had a XRF carried out on some boards that I am having solderability issues on and the report came back with 0.04um - 0.05um as the measured gold thickness. Previous batches that went through fine measured 0.07-0.11u

Hello Dave, As related to connector mating interface, fretting corrosion is the oxidation of the contact points, causing high resistance across the interface. Fretting corrosion is caused my micromotions in the interface exposing the metalized conta
