Hi after an enviromental test 85C/85RH, for 3 months (powered), of an electronic assembly with edge finger tabs ENIG finished (nickel 5micron, gold 0.02micron), the nickel disappears completely under the gold (due to corrosion, I think). Does anyone

Thanks... anyway I confirm, the nickel disappear (verified by cross section)and a strange substance greyish above gold, covering the tabs after test. I don't know the reason for this phenomenon. I don't believe that with proper electrolytic nickel fi

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.
