Abstract:
A laminate circuit structure assembly comprising at least two modularized circuitized plane subassemblies wherein each of the subassemblies comprise at least two planes having circuit traces having an external and internal surface disposed about an internal circuitized plane;dielectric between the at least two planes and internal circuitized plane; and via disposed within each sub-assembly for providing electrical communication between the planes having circuit traces and electrical connection to another of the subassemblies; and dielectric on each external surface of each plane having circuit traces and having vias; wherein the vias are filled with bondable electrically conductive material wherein the bondable electrically conductive material in the vias in the dielectric contact the bondable electrically conductive material in the planes having circuit traces for providing electrical connection to another of the subassemblies; joining layer located between each of the subassemblies wherein the joining layer comprises dielectric layers disposed about an internal electrically conductive layer has a via and the dielectric layers each have a via of diameter smaller than the diameter in the electrically conductive layer and aligned with the via in the electrically conductive layer; and wherein the vias in the dialectic layers are filled with electrically bondable electrically conductive material for providing electrical contact between the subassemblies; and wherein the subassemblies and joining layer are bonded together with a cured dielectric from a bondable dielectric; and wherein the subassemblies and joining layer are electrically interconnected with a bondable electrically conductive material.
