Patent ID: 8410672

Claim:
An arrangement for heat dissipation for a heat generating electrical component, the arrangement comprising: a heat sink having at least one recess; a printed circuit board, a bottom of said printed circuit board arrangeable on top of said heat sink, said printed circuit board comprising a dielectric substrate on top of the printed circuit board and a thermally conductive layer disposed on a top side of the dielectric substrate facing away from said heat sink; the heat generating electrical component arranged on said printed circuit board, said heat generating electrical component being disposed on the top side of said dielectric substrate facing away from said heat sink and in thermal contact with said thermally conductive layer; and a thermally conductive mounting element attached to said thermally conductive layer by means of soldering, wherein said mounting element comprises a connecting portion adapted to engage with said recess in said heat sink, thereby enabling attachment of said printed circuit board to said heat sink, so that a thermal path is provided from said heat generating electrical component, via said thermally conductive layer and said mounting element, to said heat sink, wherein said thermal path from said heat generating electrical component, via said thermally conductive layer and said mounting element, to said heat sink is the primary means by which heat is dissipated from said heat generating electrical component to said heat sink.
