The packaging concept here described involves a novel integration of first- and second-level technologies to yield a product capable of high power dissipation. It provides a relatively inexpensive three-dimensional card-on-board package that can adequately and efficiently accommodate the cooling and mounting of ceramic cards on existing second- level packages. With reference to the illustration in Fig. 1, the disclosed package provides a two-sided ceramic card 1 with edge connectors on one side that allow it to be plugged into aboard. Adjustable water-cooled jackets (cold plates) 2 are installed by means of tracks on either side of the card and are brought into contact with the module caps '3' thereon, by means of a resilient, contour forming, heat conducting material (thermoplast) 4.
