Abstract
A laminate circuit structure assembly is provided that comprises at least two modularized circuitized plane subassemblies; a joining layer located between each of the subassemblies and wherein the subassemblies and joining layer are bonded together with a cured dielectric from a bondable, curable dielectric. The subassemblies and joining layer are electrically interconnected with bondable electrically conductive material. The joining layer comprises dielectric layers disposed about an internal electrically conductive layer. The electrically conductive layer has a via and the dielectric layers each have a via of smaller diameter than the vias in the electrically conductive layer and are aligned with the vias in the electrically conductive layer. The vias are filled with electrically bondable electrically conductive material for providing electrical contact between the subassemblies.
