Thermally conductive silicone film.

Advantages: can fill the gap between the heat generating device and the heat sink very well, can be adjusted to a large thickness, to make up for the strong tolerance performance, good insulation, compression is relatively large, there is a certain shock absorption effect, silicone pad surface are with micro-adhesive, operability is very strong, relatively long service life

Disadvantages: 0.5MM below the production process is complicated, the cost is relatively high

Application environment: heat generating components and heat sink with a large gap between the case, heat generating components and shell between the thermal conductivity

Thermally conductive silicone grease.

Advantages: the product is semi-liquid, the thermal conductivity is relatively high, it can be applied very thinly, and it can fill the gap well so that the contact between the heat generating device and the heat sink is better, and the thermal resistance is relatively small, and the cost is lower compared with that of silicone film.

Disadvantages: the thickness of the coating can not be too thick, otherwise it will greatly reduce the thermal conductivity, the general thickness can not be less than 0.2MM, not suitable for large-area coating, the operation is not very convenient, after a long time use of high temperature aging, will become dry to increase the thermal conductivity of thermal resistance, there is a certain volatility.

Application environment: high power between the heating element and the heat sink, heat dissipation components need to have their own fixed devices                                                          

Thermally conductive double-sided adhesive.

Advantages: the thickness is very low, generally below 0.3MM, with strong adhesion, can be used to fix small heat sink.

Disadvantages: thickness can not be too thick, if the product has a certain gap can not be used, can not be reused, the thermal conductivity is very low.

Application scenario: the power is not high between the heat source and a small radiator, often used to fix the radiator use                             

Thermally conductive phase change materials.

Advantages: at room temperature, into a sheet, the thickness is very thin, very workable, reach a certain temperature will occur phase into a semi-liquid load, strong caulking, phase change process has an instantaneous heat absorption capacity.

Disadvantages: bad storage and transportation, relatively high cost.

Application environment: generally used in heat dissipation module more
