Abstract

Abstract A method and apparatus for making a flexible interconnect for connection between stacks of electronic components. The method includes forming a plurality of holes through a flexible insulating material, depositiong electrically conductive metal studs into the holes extending out of at least one side and preferably both sides of the flexible material, and electrically interconnecting some of the electrically conductive metal studs by interconnects supported by the flexible material. The interconnects may be supported from the outside of the flexible material or embedded therein. Dummy studs may be provided in the flexible material extending to the outside and aligned with studs extending on the other side of the insulating material which are connected to the electrical interconnects.
