Thermal Interface Material
Thermal Pad
|
Thermal pad is also known as thermal conductive silicone gap filler, thermal gasket, soft thermal pad and other different names. Generally speaking, thermal pad is composed of silicone gel combined with thermal conductive powder to achieve different characteristics such as thermal conductivity, insulation, and compressibility. |

Taking into consideration the gap distance between the heating element and the heat sink, the tolerance, and the mechanism of assembly, the smaller the thickness, the larger the thermal conductivity, and the larger the contact area, the more effective the thermal conductivity can be, provided that the Thermal Pad can effectively contact the surfaces of both objects.

Thermal Conductivity | Dielectric Breakdown Voltage | Hardness |
The thermal conductivity of a material is a measure of its ability to conduct heat. | Dielectric breakdown voltage is a long reduction in the resistance of an electrical insulator when the voltage applied across it exceeds the breakdown voltage. |
Higher numbers on the scale indicate a greater resistance to indentation and thus harder materials. |
