Thermal Conductivity(W/mk)
Dielectric Breakdown Voltage(KV)
Material Type

Thermal interface materials have been generally used in all heat dissipation modules to fill the gaps and uneven holes on the surface of the electronic materials, otherwise it will seriously hinder heat conduction. With the pursuit of high-power performance in electronic products, in addition to the pursuit of thermal conductivity of thermal interface materials, material reliability and the reduction of interface thermal resistance are more important issues.


Heat Theorem

The surface of different components may have unevenness that is not visible to the naked eye, which greatly reduces the contact area between the two surfaces.


Selection Guide

The types of thermal interface materials include thermal pad, thermal tape, thermal grease, and thermal putty. In order to accelerate heat transfer by filling the gap between the chip heat source and the heat sink, the heat energy of the chip is effectively transferred to the heat sink fins, which also improves the life of the chip and the product usage efficiency.

Metal-based, with a radiant paint coating, can more effectively in product’s heat dissipation. Polyimine is used as a substrate and is commonly used in electronic products that require high electrical insulation.


All heat dissipation begins with thermal conductivity.

When new electronic products are introduced, the IC process and chip efficiency are greatly increased according to the production process capability and market demand, and the user experience must be taken into account to pursue the thin, light weight, small, and high efficiency, resulting in high density of heat on the surface of the heating element. The heat is continuously transferred to the heat sink through thermal conduction, and eventually the thermal balance is achieved without overloading the product's mechanical components.Due to the contact surface of different components between products, there is a so-called interface thermal resistance to be considered when heat is transferred. Moreover, the surface of different components may have unevenness that is not visible to the naked eye, which greatly reduces the contact area between the two surfaces. In this case, it is necessary to rely on the Thermal Interface Material (TIM) to fill the micro voids and uneven surface holes created when the two materials are joined or contacted to reduce the resistance to heat transfer.

By using different thermal interface materials, the most suitable thermal resistance, heat flux, compressibility, hardness can be selected for different product designs, which is the key point to be considered at the early stage of product design.

   Thermal conductivity
   The ability of a given material to conduct/transfer heat

   Dielectric Breakdown Voltage

   The voltage at which a given insulating object becomes conductive


   Higher softness numbers indicate harder materials.
