Abstract
The present invention discloses heat sinks comprising a base and a plurality of fins protruding from one surface of the base, wherein the base and the fins are independently composed of one or more anisotropic thermal conductive films. Said anisotropic thermal conductive film is electric insulative with low Dk and Df values. Also disclosed are methods for manufacturing the heat sinks and methods for dissipating heat of electronic devices having at least one heat generating component.
