Flash gold is just thin electrolytic gold plating over electroless nickel or electrolytic nickel. Flash gold plating ... * Less than 3 microinch thick will be porous and take solder poorly * Greater than 10 microinch thick will cause brittle solder c

The answer, as stated above, is 3 microinch's however, it is equaly important, if not more important, to understand that the only function of the gold is to protect the surfaces beneath it. Only enough gold to cover the nickel beneath it should be u

There are many things that can go wrong when soldering to gold plate over nickel surfaces. First of all, we know that gold and solder are not good friends, as any time solder comes into contact with gold, something seems to go wrong. Either the solder bonds to the gold and eventually pulls off as the tin and gold cross-migrate, leaving voids; or the solder completely removes the gold and is expected to bond to the metal which was under the gold.

Gold embrittlement in SnPb solder is a well-known failure mechanism in electronic assembly. To avoid this issue, prior studies have indicated a maximum gold content of three weight percent. This study attempts to provide similar guidance for Pb-free (SAC305) solder. Standard surface mount devices were assembled with SnPb and SAC305 solder onto printed boards with various thicknesses of gold plating. The gold plating included electroless nickel immersion gold (ENIG) and electrolytic gold of 15, 25, 35, and 50 microinches over nickel. These gold thicknesses resulted in weight percentages between 0.4 to 7.0 weight percent.
