Thermal conductive silicone film with the arrival of 5G electronic products will usher in a new spring, the following Cushion Electronics will introduce how to choose high-quality thermal conductive silicone film:.

A. Product structure design selection

In the early stage of the structure design of electronic products should consider the integration of thermal conductive silicone film into the design issues, in different requirements and use of the environment, the thermal solution is different, should be combined with the actual situation, choose the optimal thermal solution, design a reasonable thermal structure, so that the role of thermal conductive silicone film to maximize.

Second, the choice of thermal conductivity of the thermal conductive silicone film

Thermal conductivity selection, one depends on the effect you expect to achieve, the other depends on the size of the heat source power consumption, and the heat dissipated by the design of the heat sink or thermal structure. According to these needs, choose the thermal conductivity of the thermal conductive silicone film. The cost of low thermal conductivity is relatively low, and the high thermal conductivity can be effective and costly.

Third, the choice of thickness of the thermal conductive silicone film

The thickness should take into account the heat dissipation program used in the electronic product itself. If you choose the heat dissipation structure, you need to consider the structure of the heat dissipation structure in the contact surface, and make a good balance in the design of the structure and the thickness of the thermal conductive silicone film. Thickness selection is also related to the hardness, density, compression ratio and other parameters of the product.

Four, the choice of the size of the thermal conductive silicon film

The best way to size the thermal conductive silicone film is to be able to cover the heat source. Breakdown voltage, resistance, surface resistivity, etc. can meet the conditions.

To sum up: the most important thing to choose the thermal conductive silicon film is to understand its thermal conductivity, thickness, hardness and breakdown voltage.
