Abstract
A multi-chip module (10) has a plurality of functional circuits each disposed within its own cavity (15-18), each cavity separated from the other by isolation channels (20, 21). Each functional circuit includes a plurality of monolithic microwave or high speed digital integrated circuit chips (29-33) which are wire bonded or flip-chip attached to the multi-chip module, and each is encapsulated in plastic (37) overmold compound. Complete electromagnetic shielding is provided by depositing metal (23) over the channels and the plastic encapsulation, thereby providing a totally electromagnetically channelized and shielded multi-circuit, microwave and/or high speed digital integrated circuit board.
