Hi,
gold plating is common PCB finish. Embrittlement depends on gold
thickness. Simply, the more Au the more embrittlement.

Subject: [TN] Gold Board

Good morning TechNetters (at least here on the left coast),

We have a small assembly that requires a couple of pads to be gold
plated. We would like to gold plate the entire board but we're concerned
about gold embrittlement when we solder the components in. The board is
completely through hole and will be both wave soldered and hand
soldered.

Do you think we have any concerns? Oh by the way this is a class 3
assembly.

Thanks,

KennyB
