Abstract:
A method for fabricating a laminate circuit structure assembly which comprises: providing 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;providing a dielectric material between the at least two planes and internal circuitized planes; and providing 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 providing 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 contacts the bondable electrically conductive material in the planes having circuit traces for providing electrical connection to another of the subassemblies; locating a joining layer between each of the subassemblies wherein the joining layer comprises dielectric layers disposed about an internal electrically conductive layer wherein the electrically conductive layer has a via and the dielectric layers each have a via of smaller diameter than vias in the electrically conductive layer and aligned with the vias in the electrically conductive layer; and wherein the vias in the dielectric layers and electrically conductive layer are filled with electrically bondable electrically conductive material for providing electrical contact between the subassemblies; and providing as a bonding member a bondable curable dielectric between the joining layer and subassemblies; and providing a conductive member for providing electrical interconnection between the joining layer and subassemblies; aligning the subassemblies, joining layer and bonding member; and then laminating to cause bonding of the joining layer to the subassemblies.
