发明名称 Method of assembly of microwave integrated circuits having a structurally continuous ground plane
摘要 One or more MIC's (microwave integrated circuits) are included in an assembly having a structurally continuous ground plane of conductive material for the microwave circuitry. Individual MIC's are mounted on a carrier and attached thereto by a layer of a dielectric adhesive. The adhesive is in contact with and interposed between the lower side of each MIC substrate and the carrier which may be, for example, a metal chassis. The carrier serves as, or includes, the structurally continuous ground plane of conductive material. Ground plane metallization on the lower side of MIC substrates is thereby made unnecessary. The dielectric adhesive may be maintained in a liquid or tacky state to permit convenient removal from the assembly of an MIC requiring rework or replacement. In addition, the layer of dielectric adhesive provides a thermally conductive path between an MIC and the carrier making the invention particularly well suited for MIC assemblies which are intended to be operated in a vacuum.
