Usually in the selection of thermal silica gel sheet, should think about: electronic product structure, thermal conductivity, scale, thickness, thermal resistance and expected to reach the role.

Note on choosing thermal silicone material:

1. Product structure design selection In the early stage of the structural design of electronic products should consider the thermal silicone sheet into the design problem, in different requirements and use of the environment, the heat dissipation scheme is different, should be combined with the actual situation, choose the best heat dissipation scheme, design a reasonable heat dissipation structure, so that the thermal silicone sheet to maximize the role.

2. The selection of thermal conductivity of thermal conductivity of thermal conductivity of thermal conductivity selection, one depends on the effect you expect to achieve, the other depends on the power consumption of the heat source, and the heat dissipation of the design of the radiator or heat dissipation structure. According to these requirements, the thermal conductivity of the thermal conductive silica gel sheet is selected. The cost of low thermal conductivity is relatively low, and the effect of high thermal conductivity is good, and the cost is also high.

3. Selection of thickness of thermal conductive silicone sheet This thickness should take into account the heat dissipation scheme used by the electronic products themselves, if it is to choose the heat dissipation structure, it is necessary to consider the shape structure of the heat dissipation structure in the contact surface, and balance the design structure and the thickness of the thermal conductive silicone sheet. The thickness selection is also related to the hardness, density, compression ratio and other parameters of the product.

4. The best way to choose the size of the thermal conductive silicone sheet is to cover the heat source. Breakdown voltage, resistance, surface resistivity, etc. can meet the conditions.
