The Thermal Pad can fill the gap between the heat source and the radiator, quickly transferring heat to the radiator and reducing the temperature of the heat source. Due to the collision and rupture of components during vibration, the elasticity of the Thermal Pad can protect the components, tightly combining the heat source and heat sink to prevent deformation of the components due to strong impact or removal of the casing from the host. The thermal pad is electrically insulating. It improves the thermal conductivity and mec-hanical tolerance of the product, and enhances the efficiency of the components.
