Talk about the correct installation method of thermal conductive silicone pad

One of the high thermal conductive silicone pad heat transfer interface materials, with its excellent thermal conductivity, good insulation, excellent fire resistance, good cushioning, controllable self-adhesion, optional thickness, and color Tonality, simplicity of construction, and stability of quality have become a highly thermally conductive medium in the production of modern electronic products. It plays a good role in connecting the air distance between the heating element and the heat sink. The level of pressure resistance is used to fill the space between the heating element and the heat sink. Particularly high-performance components will generate a large amount of heat under high-speed operation. This heat is immediately removed to ensure that the components can be used at normal operating temperatures. Efficient operation.
 
It was then widely used in many electronic products, such as: high-power LED lamps, automotive electronic modules, power modules, calculator applications (CPU, GPU, USICS, drivers), solar energy industry, backlight industry, LED-TV / PDP, etc. Wait.
Here are 5 steps to give you an example to explain the installation steps of the thermal pad:
1. Keep the electronic components and the thermally conductive silicone sheet clean and clean to avoid dirt on the surface of the electronic components. Any dirt on the contact surface will cause the thermally conductive silicone sheet to have poor self-adhesion and seal thermal conductivity.
 
2. When removing the thermally conductive silicone sheet, the thermally conductive silicone sheet with a large area should be grasped from the heart. The grasping of the sheet with a smaller area is not required because the large thermal pad is unevenly stressed, which will cause deformation and affect Subsequent operations can even damage the silicone sheet.
       
3. Holding the thermal conductive silicone pad in one hand, tear off one side of the protective film with the right hand. Remember that you cannot remove the protective film on both sides at the same time, try to reduce the number and area of ​​direct contact with the thermal conductive silicone sheet, and keep the thermal conductive silicone sheet's self-adhesion and thermal conductivity from being damaged.
 
4. Remove one side of the protective film and first align the heat sink toward the electronic component to be pasted. When slowly lowering the thermal pad. Be careful to avoid air bubbles.
 
5. If air bubbles are generated during operation, pull up one end of the silicone sheet and repeat the above steps, or use a hard plastic sheet to gently wipe off the air bubbles. The force must not be too large to avoid damage to the thermally conductive silicone sheet.
