Generally, before selecting a thermally conductive silicone sheet, you should consider the following: electronic product structure, thermal conductivity, size, thickness, thermal resistance and expected effects, etc.

Things to note when choosing thermally conductive silicone materials:

1. Product structure design selection In the early stage of structural design of electronic products, thermal conductive silicone sheets should be considered to be integrated into the design problem. Under different requirements and usage environments, the heat dissipation solutions are different. The optimal heat dissipation solution should be selected based on the actual situation. , a reasonable heat dissipation structure is designed to maximize the effect of the thermally conductive silicone sheet.

2. Selection of thermal conductivity coefficient of thermally conductive silicone sheet. The selection of thermal conductivity coefficient depends on the effect you expect to achieve, and the other depends on the power consumption of the heat source and the heat that the design of the radiator or heat dissipation structure can dissipate. Select the thermal conductivity of the thermally conductive silicone sheet based on these needs. The ones with low thermal conductivity are relatively low-cost, while the ones with high thermal conductivity are more effective but the cost is higher.

3. The thickness of the thermally conductive silicone sheet should be selected based on the heat dissipation solution used by the electronic product itself. If you choose a heat dissipation structure for heat dissipation, you need to consider the shape and structure of the heat dissipation structure at the contact surface. When designing the structure and the thermally conductive silicone sheet Make a good balance in thickness selection. The thickness selection is also related to the hardness, density, compression ratio and other parameters of the product.

4. Selection of the size of the thermally conductive silicone sheet. The best way to size the thermally conductive silicone sheet is to cover the heat source. The breakdown voltage, resistance, surface resistivity, etc. only need to meet the conditions.
