Abstract:
A method of forming a microwave monolithic integrated circuit (MMIC) package comprising the steps of:providing a base plate that is matched as to its coefficient of thermal expansion (CTE) with a MMIC to be packaged; placing a solder preform onto the base plate; placing on to the solder preform a single MMIC having one or more pads; placing a chip cover having openings over the MMIC to cover the chip to form a MMIC package that can be automatically picked and placed, wherein the base plate and cover are configured with respective portions that contact each other such that any pads on the MMIC are directly exposed through the openings of the chip cover for wire and ribbon bonding to a circuit board without interconnects attached to the pads on the MMIC; and heating to flow the solder preform and secure the MMIC to the base plate.
