Bob, I don't think this will help, if the contacts are rubbed down to laminate level.... But RHODIUM plating has been used in high wear applications....better than Au. We used to have Rhodium bath....not anymore.

These boards are heavily weighted down with water-cooled heat sinks and heavy transformers. In the end use environment the boards are vibrated under load and eventually the hard gold 4 um thick goldfinger contacts are rubbed down to the laminate level. Besides a mechanical redesign any other plating surfaces anyone would recommend? Thanks!
