introduce Thermally conductive materials
2018-12-06Auther: Thermo Electronic Technology Co., Ltd

Thermally conductive materials are designed and developed for the heat transfer requirements of equipment, with excellent performance and reliability. They are suitable for a variety of environments and requirements, and have appropriate countermeasures for various heat dissipation problems that may arise, which provide a powerful help for the highly integrated equipment and ultra-small and ultra-thin product design.

The ideal thermal interface material should have the following characteristics:

     1, high thermal conductivity

     2, high flexibility, to ensure that at the lower installation pressure, the material can fill the gap of the contact surface to the fullest, ensuring that the contact thermal resistance between the thermal interface material and the contact surface is small.

     3, insulation

     4, easy to install and detachable

     5, wide applicability, can be used to fill small gaps, but also fill large gaps.


Type of thermal conductive material:

     1, thermal grease

     The thermal conductive silicone grease is made of organic silicone as a main raw material, and is made of a material having excellent heat resistance and thermal conductivity, and is made of a thermally conductive silicone grease composite for use in heat conduction of power amplifiers, transistors, tubes, CPUs, and the like. Heat dissipation to ensure the stability of electrical performance of electronic instruments and meters.
