The Impact of Silicone Thickness on Electronic Products

The impact of silicone thickness on electronic products

In the use of modern electronic products, the divergence problem is extremely serious. In order to ensure the operating efficiency, we must actively solve the problem of heat dissipation. For example, in the PC, to solve the central processing unit heat problem. Thermal grease is usually added between the radiator and the CPU. Today, as science advances and electronic products run faster and faster, heat dissipation is still a major problem that manufacturers are trying to solve. At present, thermal conductivity silicone sheet is widely used, known as a new generation of thermal conductivity new technology. It shows the possibility of replacing silicone grease as soon as it is marketed, and its choice depends largely on its thickness.

 First, the thickness will directly affect the thermal resistance coefficient

 Thermal resistance coefficient refers to the resistance encountered in the process of heat transfer. Literally, the lower the resistance, the higher the thermal conductivity, and the thermal silicone grease used in early personal computers had a very low thermal resistance, making it very popular among various manufacturers. However, the problem of large silicone grease is that it may fall off after long-term use. The thickness of the thermal conductivity silicone sheet determines the thermal resistance coefficient. However, it should be explained here that the thinner the conductive silicone sheet, the better the thermal conductivity. The choice of thickness mainly depends on the specific heat dissipation object.

 Second, the thickness is different, the price is different

 Thermal conductive silica gel sheet has shrinkage, so to a certain extent, it also plays a seismic role on electronic products, can be seismic, conduction of excess heat. Thermal conductive silica gel sheet thickness is different, the price is also different. When the conductive silica gel is used for electronic products, the thickness should be determined according to the actual situation. Too thick or too thin creates a corresponding waste. Usually, thicknesses can be selected from a wide range, ranging from 0.5 mm to 1.5 mm. The different thickness determines the length of the heat transfer path and also determines the size and price of the thermal resistance coefficient.
