Abstract
In one or more embodiments, a method for applying a thermal interface material (TIM) to a heat sink involves treating a plurality of sections of a base layer around at least a portion of a perimeter of the heat sink to form a continuous roughness edge and positioning the TIM relative to the heat sink such that the TIM extends for contact with the roughness edge. The roughness edge is based on reducing the adhesion force between the TIM and the base layer, wherein the TIM is easier to remove from the roughness edge, resulting in easier and cleaner removal of the TIM from the heat sink.
