Abstract:

The present invention provides a heatsink for use with a heat-generating electrical component. The heatsink comprises a spine having opposing sides, cooling fins extending from the spine, and a dielectric layer adhered to at least one of the opposing sides. The dielectric layer has a thermal conductivity of at least about 1 W/m. degree. C. The heatsink may further comprise a metal layer adhered to the dielectric layer. The metal layer provides a surface to which an electric component can be adhered. The heatsink can further include a heat-generating component adhered to the metal layer. In another aspect, the heat-generating component is a surface-mount electrical component adhered to the metal layer with solder.
