Abstract
A printed wiring board carries electronic components. A castable body is of thermally conductive dielectric material and is molded from the printed wiring board to the exact configuration of the electronic devices. A metal plate completes the conductive converter, which includes the castable body. The conductive converter can be clamped to a cold plate and a card box to conductively remove heat from the electronic components. The molding process may be direct molding of the castable body onto the electronic device side of the printed wiring board or may include indirect steps. Protection of the electronic devices and printed wiring board and filling of the undercuts may be accomplished by vacuum-forming an electrically conductive polymer sheet over the devices during molding followed by removing of the sheet when the thermal mounting plate is attached.
