Abstract
The electronic package (10) is comprised of a plurality of support plates (12-24), each of which has a plenum therein and preferably webs extending into the plenum for fluid flow control and heat transfer. A wafer (104) is mounted in a recess (100) in the support plate (12) so that fluid in the plenum (52) directly cools the wafer. Electrical connection is by flexible cable (108) to an exterior printed wiring board (40). The package may have any selected number of support plates, and each support plate may carry one full-sized wafer for compact packaging.
