Advanced Institute of Technology produces alternative thermal conductive absorbing materials to Laird

Thermal conductive absorbing materialIt has dual functions of thermal conductivity and absorption, which is completely different from standalone absorbing and thermal conductive materials. Now, let me briefly introduce the characteristics of thermal conductive absorbing materials:

1. The absorbing materials are all hard materials with a Shore A temperature of 60 degrees or above, and most of the absorbing material matrix is made of solid silicone rubber. There is a significant difference between absorbing materials and thermally conductive absorbing materials in this regard.

2. The thermal conductivity of thermal conductive materials is generally between 1.0W/mK-6.0W/mK. The matrix of thermal conductive materials is mostly made of liquid silicone rubber, which is soft and ensures extremely low interfacial thermal resistance. There is a significant difference between thermal conductive materials and thermal absorbing materials in this regard.

3. Even the best absorbing material has a thermal conductivity k value of only about 0.5W/mK. But under hard surfaces, the contact thermal resistance is very high. If used in processors, it can only solve electromagnetic wave interference, and the problem of heat becomes a major issue.

4. Absorbing materials often use iron and alloy powder. These metal powders will rust if they are resistant to weather conditions for a long time. Moreover, if metal powder falls onto PCB components, it may cause a short circuit in the circuit.

5. There is a significant gap between the absorption performance of thermal conductive absorbing materials and that of real absorbing materials; At the same time as having absorbing properties, it significantly reduces the thermal conductivity of the material, resulting in a lack of advantages in its thermal conductivity.

Therefore, Advanced Institute Technology has developed a thermal conductive absorbing material that combines both thermal conductivity and wave absorption characteristics in the market, replacing itLaird thermal conductive absorbing material
