Back in the 50's, 60's and 70's gold plated boards were all the rage for high reliability. test equipment, milspec etc. Nowadays only edge connectors are gold plated. Immersion plated gold is also used but it doesn't last the distance like gold plate

Chemical gold is a poorly defined [very sloppy] term that means various thing to different people [as you've demonstrated]. Commonly it is either: * ENIG: 5�m Ni, 0.1�m Au * Immersion gold "Autocatalytic chemical gold plating" - Refers to "electrol

When discussing this with the customer he said that his vendor recommended a hard gold plating finish on the board due to the BGA. I said "hard gold"??? And he said yes, hard gold. Turns out the boards were plated with hard gold, not ENIG. Thank
