Therm-A-Gap
THERM-A-GAP® thermal interface materials fill air gaps between hot components and heat sinks or metal chassis. Their flexible, elastic nature allows them to blanket highly uneven surfaces. Heat is conducted away from separate components or entire PCBs into metal covers, frames or spreader plates.
The purpose of the gap filler in the joint is to replace the air gap with something that is at least 30 times more conductive than air and in intimate contact with both the surface of the component and the heat sink. When choosing the gap filler take account of the maximum pressure that the component can take along with the tolerance on the gap.
