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
