Hi Kevin,
MIL-G-45204 is the military specification for electrodeposited gold plating.
For hard and soft gold plating, the purity of the gold and its hardness
values are to be considered.
If you need to solder components on to the pcbs, then ENIG or ENEPIG would
be a better option.

Subject: [TN] PCB finish: ENIG vs. hard gold
Hi everyone,
We have a PCB supplier who is offering "Hard Gold" as an alternate to ENIG
finish, due to PCB size and processing capabilities. The application is
Class 3 (mil/aero). The circuit is thin FR4 and subject to SMT reflow w/
Sn63Pb37 (non RoHS) solder alloy, and moderate flexing in end application.
Can anyone offer info on the differences between the two finishes, and/or
their suitability? Is there an IPC spec (or specs) that outline "hard
gold"?
Thanks,
Kevin Glidden
