Abstract: A process of fabricating an electromagnetic circuit includes providing a first sheet of dielectric material including a top surface having at least one conductive trace and depositing a solder bump on the at least one conductive trace. The process further includes applying a second sheet of dielectric material to the first sheet of dielectric material with bond film sandwiched in between, the second sheet of dielectric material having a through-hole providing access to the solder bump. The process further includes bonding the first and second dielectric materials to one another and removing bond film resin from the solder bump. The process further includes machining the solder bump by the drilling or milling process to achieve a desired amount of solder in the solder bump.

Abstract: A circuit structure includes a signal substrate having a signal trace formed thereon and a microstrip substrate disposed above the signal substrate that includes a microstrip trace formed thereon and a hole passing through it. The circuit structure also includes a conductor passing through and substantially filling the hole passing through the microstrip substrate and electrically contacting the signal trace on the signal substrate and a flat wire connector electrically connecting the microstrip trace to a first end of the conductor, the flat wire connector being arranged such that a gap is formed between the flat wire connector and a top surface of the microstrip substrate.

Abstract: A method of forming a heat-dissipating structure for semiconductor circuits is provided. First and second semiconductor integrated circuit (IC) chips are provided, where the first and second semiconductor chips each have first and second opposing sides, wherein the first and second semiconductor IC chips are configured to be fixedly attached to a top surface of a substantially planar circuit board along their respective first sides.

Abstract: An electronic subsystem such as an array of radar transmit/receive microwave modules are associated with (e.g., base mounted to) spaced heat sinks. There is an electronic module on each side of each heat sink and an inflatable bladder or “pneumatic pressure wedge” between adjacent heat sinks biases a pair of electronic modules against their respective heat sinks.
