Abstract
A heat sink is created from a single or multiple lengths of compressed, corrugated fin, eliminating the need for a heat sink base plate. A length of corrugated fin is compressed in a fixturing operation to form a continuous top flat surface and a continuous bottom flat surface. After the fixturing operation, a bonding operation is performed to generate permanent continuous top and bottom flat surfaces on which elements requiring temperature control may be mounted directly, eliminating the cost and weight of a base plate.
