Abstract : Working with the U.S. Army Space and Strategic Defense Command, the Army Research Laboratory has developed an easy-to-produce, reliable, high-temperature printed circuit board for radiation studies of circuits that use silicon carbide transistors. This board is designed to operate at temperatures beyond 300 deg C. The board consists of an alumina substrate with thick-film gold traces. Stainless-steel pin receptacles are used to mount the transistors, allowing easy insertion and removal. Ruthenium oxide resistors are glued to the substrate and wire-bonded for electrical connection.
