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° 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.

Abstract: Spring clips with nesting end portions are disclosed for use in securing heat generating electrical devices to a support surface, such as a heat sink. The nesting end portions of the clips depend downwardly below the main body portion to prevent contact with edges of electrical devices of varying height and width. Thickness and temper of the clips provide some flexibility so there is less variability in clamping force applied to the clamped devices by the clip in response to tightening of the attachment means and torquing of the fastening means becomes less critical.
