Abstract
Disclosed is a parallel processor packaging structure and a method for manufacturing the structure. The individual logic and memory elements are on printed circuit cards. These printed circuit boards and cards are, in turn, mounted on or connected to circuitized flexible substrates extending outwardly from a laminate of the circuitized, flexible substrates. Intercommunication is provided through a switch structure that is implemented in the laminate. The circuitized flexible substrates connect the separate printed circuit boards and cards through the central laminate portion. This laminate portion provides XY plane and Z-axis interconnection for inter-processor, inter-memory, inter-processor/memory element, and processor to memory bussing interconnection, and communication. Lamination of the individual subassemblies is accomplished with a low melting adhesive that is chemical compatible with (bondable to) the perfluorocarbon polymer between the subassemblies in the regions intended to be laminated, and, optionally, a high melting mask that is chemically incompatible with (not bondable to) the perfluorocarbon polymer between the subassemblies in the regions not intended to be laminated. The subassembly stack is heated to selectively effect adhesion and lamination in areas thereof intended to be laminated while avoiding lamination in areas not intended to be laminated.
