Abstract

A stamped and formed heat sink has a thermally conductive body including a base having a face adapted for attachment to an electronic device package. Stamped and formed heat dissipation elements extend from the edges of the base perpendicular to the base. The heat sink is formed in a progressive punch and die press so that a heat sink is produced on every stroke.
