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.
Claims10
A method for attaching a thermal interface material (TIM) to a heat sink positioned on a base layer, the heat sink having a heat sink length and a heat sink width, the method comprising:
- treating a plurality of sections of the base layer around at least a portion of a perimeter of the heat sink, wherein each treated section of the plurality of treated sections comprises a width, and wherein one or more of the width and the surface roughness of each treated section of the plurality of treated sections is based on the TIM, and wherein the plurality of treated sections form a continuous roughness edge;
- and
- applying the TIM to the heat sink, wherein a portion of the TIM extends onto the roughness edge around the heat sink.
