I am wondering if you would be able to answer the following for me.

We have been recieving PCB's with imperfections on the goldfingers which
appear to be either the lack of plating or the presence of solder. What
class 2 standards are implicated and how should they be interpreted? What
dimensions apply to the critical contact area?

Regards

Alex Holmes
