ABSTRACT:
A heat generating electrical device is connected to a heat sink of metal. An element, preferably formed of copper or silver and plated to increase ease of soldering and corrosion resistance, is mechanically anchored in the thickness of a heat sink (e.g. of aluminum or steel) so that part of the element is accessible. Then the electrical component is soldered to the accessible part of the element. The mechanical anchoring may be accomplished by punching, drilling, or the like, and locating in the hole so formed a copper stud having a head abutted against a plate, and then compressing the assembly mechanically to anchor the stud in the plate, with the electrical components soldered to the stud head.
