 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.

Subject: [TN] Gold Finger Plating for High Vibration Environments


Dear Technetters:

We are trying to advise a client on PCB specifications for a future product 
build. 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!


Regards

Bob Wettermann
