Abstract:
An electrical device comprising:a printed circuit board (10) carrying an electronic circuit and having a plurality of electrically conducting conductor tracks and a metal cladding as heat conductive layer (13) for heat conduction, said heat conductive layer (13) also serving as an electrically conducting element and being arranged in an edge region (32 to 34) of said printed circuit board (10);at least one power component (11) to be cooled, said at least one power component (11) being electrically connected with at least one of said electrically conducting conductor tracks, being arranged in said edge region (32 to 34) and resting on said heat conductive layer (13) in said edge region (32 to 34) so that heat generated in said at least one power component (11) is conducted away by said heat conductive layer (13); anda cooling element for dissipation of the heat conducted from said at least one power component (11) by said heat conductive layer (13) to said cooling element;wherein said heat conductive layer (13) in said edge region (32 to 34) has a thickness greater than a thickness of said conductor tracks in another region of said printed circuit board outside of said edge region (32 to 34).
