Hard Gold plating
Gold plating has excellent electrical and thermal conductivity, it also offers exceptional solderability and is a superb reflector of infrared radiation. Alternate Finishing can provide two different types electrolytic gold plate and electroless gold. Each serves a different purpose;
Is used for contacts such as edge board connectors or a key pad. The hard gold we use is also a solderable gold.
The thickness specified for contacts is either .8 microns (30 microinches) minimum or 1.3 microns (50 microinches minimum). The thickness specified for solderability should be a maximum of .8 microns (30 microinches).
This gold meets the requirements of Mil-G-45204 and Mil-DTL-45204, type I or type II, grade C. It also meets the requirements ASTM B-488-01, type I or type II, code C.
