Patent ID: 8633584

Claim:
An electronic assembly comprising: a base layer; one or more electronic components each having a conductive bump at each of a plurality of electrical terminals, wherein each of said bumps comprises a wire, wherein the wire is bonded to one of the electrical terminals and forms a pointed distal tip; an interconnection circuit on the base layer, the interconnection circuit comprising: at least two layers of conductive traces with a dielectric material between each pair of adjacent layers, wherein two traces of different layers electrically contact each other to form an interlayer connection, and a plurality of wells, each containing therein a portion of one of the bumps of the electronic components, and a portion of at least one of the two traces, wherein the portion of the trace within each well is configured to directly contact a portion of the one bump and to conduct current between the one bump and the other of the two layers of conductive traces; and a conductive material within each well, the conductive material forming an electrical and mechanical connection between the portion of the bump within each well and the portion of the layer of conductive traces within each well, the conductive material having a lower melting point than the bumps.
