Abstract:
A method for the fabrication of electrical contacts comprising the steps of:a) through-plating a plurality of a plurality of vias in a substrate; b) forming a plurality of domes in a first metal sheet; c) placing a first mask layer on said first metal sheet; d) first etching said first metal sheet in all areas not protected by said first mask layer thereby producing a plurality of electrical contacts, wherein said electrical contacts include spiraling legs configured to create a wiping action on metal pads; e) soldering said etched first metal sheet to said plurality of through-plated vias; f) placing a second mask layer on said etched first metal sheet; and g) second etching said etched first metal sheet in all areas not protected by said second mask layer resulting in the physical and electrical separation of at least some of said plurality of electrical contacts.
