1. To protect the nickel and copper under gold plating from oxidization before soldering. Gold plating can extend the PCB self-life and improve the solderability for 2nd re-flow. 2. Provide a good bonding strength. For Chip on Board process that Gol

I'm not 100% sure which type of gold you're asking about, but if you're talking about hard gold plating, I think the most common use is to provide a durable surface for things like membrane switch contacts because it resists abrasion and other mechan

We'd suggest using your connector supplier recommendations. Some use: * Pad Plating: 20-30 uin Au over 50 uin Ni (You might get away with less gold) * In-Pad Vias: less than half the diameter of the button (for contact-only configurations) * PCB/C
