Abstract:
A printed wiring board for mounting high power dissipating components comprising:a thermally conductive base plate for dissipating heat produced by the components;a first dielectric layer having a top surface and a bottom surface, said bottom surface thereof disposed on said base plate;an electrically conductive trace disposed on said top surface of said first dielectric layer;a second dielectric layer having a top surface and a bottom surface, said bottom surface thereof disposed on said top surface of said first dielectric layer; andsaid second dielectric layer including an aperture for exposing said electrically conductive trace on said top surface of said first dielectric layer, such that the components are mounted through said aperture for electrical contact with said exposed electrically conductive trace, thereby locating the components in close proximity to said base plate for enhancing thermal coupling between the components and said base plate.
