Abstract:
1. A method of forming a plurality of electrically conductive contact structures on an electronic component comprising a plurality of electrically conductive contact elements, each said contact structure comprising a base connected to one of said contact elements and a beam, said method comprising: depositing a layer of moldable material on said electronic component; providing a stamping tool comprising a plurality of protruding regions, a plurality of contoured regions, and a plurality of recessed regions, each said protruding region defining a base of one of said contact structures and corresponding to one of said contact elements on said electronic component, each said contoured region defining a beam of one of said contact structures, and each said recessed region defining a separation between adjacent ones of said contact structures; aligning said protruding regions of said stamping tool with said contact elements of said electronic component; pressing said stamping tool into said moldable material, said plurality of protruding regions forming molds in said moldable material of bases of said contact structures, and said plurality of contoured regions forming beam molds in said moldable material of beams of said contact structures; and depositing contact structure material into said beam molds and said base molds.
