Thermally conductive silicone film is also called thermally conductive silicone pad. Thermally conductive silicone film has a good thermal conductivity and high-level pressure resistance. It is a thermally conductive composite material with great Chinese craftsmanship and practicality. Silicon is the old name for silicon. Glue can generally be called silica gel. Thermally conductive silicone sheet is one of the types of silicone products. In Taiwan and some other Asian countries and regions, thermally conductive silicone sheet is still called thermally conductive silicone film. Thermally conductive silicone gaskets have a wide range of applications, mainly for enterprises. Electronic control appliances, automotive engineering machinery, and other internal research as components that affect heat dissipation and insulation can be used for a long time and have no corrosion to metal components. So what are the safety precautions that we need to pay attention to when using it?
When purchasing thermally conductive silicone foot pads suitable for students’ own enterprise products, the heat source, insulating thermally conductive silicone sheet, and the top cover of the radiator should be kept in full contact, and there should be no gap in between, because they are mainly between each other. It is to conduct heat by contact. If there is a gap in the middle, it will greatly increase the social contact thermal resistance, thereby reducing the thermal conductivity. In the long-term development work, the temperature should be maintained between -50 and 200 ℃.
Due to the easy adhesion of silica dust, the process should maintain a clean and flat heat-insulating and thermally conductive silicone sheet, Sanhe radiator cover, which can prevent dust and dirt from affecting thermal conductivity and viscosity.
Products are widely used in IGBT, power module, MOS tube heat dissipation, CPU, heat sink, heat conduction source and other fields. According to the performance requirements you need, choose a silicone foot pad with thermal conductivity, insulation suitable for you, and double-sided adhesive self-adhesive characteristics.
Although silica gel has good anti-vibration and anti-compression properties, it should be handled carefully and evenly pressured during transportation to avoid damage to the insulating and thermally conductive silicone gasket, so as to better play the role of the insulating and thermally conductive silicone.
The silicone pad itself is a material with thermal conductivity and thermal insulation properties, which has good EMC protection and is not easy to puncture and tear or is compressed when it is damaged. Silicone material is a good EMC reliability. Thermally conductive silicone lipids are prone to dryness on the surface during the room temperature curing process, are unstable at high temperatures, are easy to volatilize and flow, and their heat capacity will gradually decrease, which is not conducive to long-term reliable system operation.
