How To Use Thermally Conductive Silicone Sheet Correctly?

Thermally conductive silicone sheet is a highly efficient heat conduction material, which is widely used in electronic equipment, LED lighting, power modules and other fields that require heat dissipation. Correct installation of Thermally conductive silicone sheet can not only improve the heat dissipation efficiency of the device, but also extend its service life.

1. Choose the right Thermally conductive silicone sheet

Generally speaking, the higher the thermal conductivity, the better the heat dissipation effect, but the cost will also increase at the same time.

Thermal conductivity (W/m·K): Choose the right thermal conductivity to meet the heat dissipation needs of the device.

Thickness: Thinner silicone sheets have better thermal conductivity, but the ability to fill gaps also needs to be considered.

Size: Cut according to the contact area between the heat sink and the chip to ensure complete coverage.

2. Clean the contact surface

Before installing the Thermally conductive silicone sheet, the surface of the device must be cleaned to ensure that there is no dust, oil or other impurities.

3. Correctly install the thermally conductive silicone sheet

During installation, it is necessary to ensure that the silicone sheet can fit the heat sink and heating element tightly to reduce air gaps and improve thermal efficiency.

Method 1: Direct bonding

·Tear off the protective film and gently stick the thermal conductive silicone sheet on the surface of the chip or device that needs heat dissipation.

·Press lightly with appropriate pressure to make it fit completely.

Method 2: Install with radiator

·First stick the silicone sheet on the heating element, and then install the radiator.

·Fix the radiator with screws or clips to ensure that the silicone sheet does not move.

Note: Avoid excessive force to prevent the silicone sheet from deforming or breaking, which will affect the thermal conductivity.

4. Test and check the heat dissipation effect

Temperature monitoring: Use an infrared thermometer or temperature sensor to observe whether the temperature change is as expected.

Running test: Let the device run for a while to ensure that there is no overheating problem.

5. Maintenance and replacement

Recommended replacement cycle: Generally check once every 1-2 years. If the silicone sheet is found to be hard, cracked or the thermal conductivity is reduced, it should be replaced in time.

Storage recommendation: Unused silicone sheets should be stored in a dry, room temperature environment away from direct sunlight to prevent aging.

Proper use of Thermally conductive silicone sheet can effectively improve heat dissipation efficiency and reduce the risk of overheating of electronic devices.
