Abstract
A method and apparatus for plating the posts of a semiconductor chip header is described. A means is provided for orientating the headers and feeding them in single file to a predetermined position in the apparatus. A transporting means is provided for transporting the headers from the feeding means over a plating bath such that the posts of the header are immersed in the bath. Attached to the transporting means is a plurality of clamping assemblies. Each of the clamping assemblies includes a knife-like member for electrically insulating the thru-leads of the header from its envelope lead and means for clamping the thru-leads of the header to the knife-like member. The clamping means of the clamping assemblies also include means for coupling a source of potential between the plating bath and the thru-leads clamped therein.
