摘要: The present concepts include "1:1" uniax (40) with one conductive through-hole per chip connection site, "mirror chip" testing, heat-sink bonding to chips, avoiding contact with conductive cleaved edge of chip, indium solid columns, metal recessed (41) in the through-holes. All of these are subject to preferred materials (UPILEX polyimide) and techniques (U.V. laser ablation, minimum taper of holes).

摘要: Polymer (preferably polyimide) sheets (10) with laser ablated through-holes plated with metal (20) are used for making electrical conections to specified microcircuits, especially unbumped microchips and Tape Automated Bonding (TAB) articles. Bonding with different melting point materials at opposite ends of the plated holes is disclosed. Preferred polyimides are those derived from polymerisation of 4,4'-biphenyldianhydride and (4,4'-diaminobiphenyl, or 4,4'-diaminobiphenylether, or phylenediamine, preferably p-phenylenediamine).
