ABSTRACT:
A method of fabricating a pin tip is provided by a cutting and coining operation which first forms a pin tip which has a generally rounded configuration defining 4 slightly curved convex sides joined at 4 edges converging at a pin end. Thereafter the pin tip is coined again thereby overlapping portions of the conductive plating layer over the sharp edges of the pin tip.
