3.Product features and applications of Heat-dissipating silicone sheet
The heat-dissipating silicone sheet, due to its good softness, effectively removes the air between the interfaces, so that the interfaces can be in close contact, and the efficiency of heat conduction is improved. It is specially produced for the design scheme of using the gap to transfer heat. It can fill the gap, open up the heat channel between the heating part and the heat dissipation part, effectively improve the heat transfer efficiency, and meet the design requirements of miniaturization and ultra-thin equipment. it is extremely technological and practical, and the thickness has a wide range of application, can fill any uneven gap, is an excellent heat conduction filling material. There are many advantages of heat-dissipating silicone sheet: free choice of color matching; customized shape according to customer requirements; excellent natural self-adhesion, easy assembly, convenient disassembly and assembly, and can be reused; manual operation is very convenient, outside manual operation, can be applied to automatic patches. Low-cost, high-efficiency, high-cost performance; Replacement of volatile thermal conductive silicone grease; High electrical insulation; can make heating devices of different heights use the same heat sink, there is no heat limit. High thermal conductivity: The use of heat-dissipating silicone sheets fills the gap between the heating element and the radiator, greatly improves the efficiency of heat conduction and heat dissipation, and reduces the temperature difference between the interface to a lower level. Insulation: In the heat conduction and heat dissipation of electronic products, many devices require thermal conductive materials to have insulationa to prevent electrical conduction from adversely affecting other devices. Stability: The heat-dissipating silicone sheet has good stability and can maintain good characteristics under various environmental conditions, thus ensuring the stable performance of electronic products in various environments. Sound absorption and shock absorption: The heat dissipation silicone sheet also has a certain sound absorption and shock absorption effect, so that the performance of electronic products is better, and it also plays a certain role in maintaining various components. Typical applications of heat-dissipating silicone sheets: semiconductor heat dissipation devices, communication equipment, graphics cards, memory storage modules, power supply equipment, LCD and plasma TVs, computers, network servers, LED industry use (for example: LED lighting equipment). The heat-dissipating silicone sheet is also used between the aluminum substrate and the heat sink. The power industry uses heat conduction between MOS tubes, transformers (or capacitors, PFC inductors) and heat sinks or housings. TD-CDMA products conduct heat conduction and heat dissipation between the motherboard IC and the heat sink or shell, and conduct heat conduction and heat dissipation between the set-top box DC-DC, IC and the shell. Applications in the automotive electronics industry (such as xenon lamp ballasts, audio, vehicle series products, etc.) can be used to heat-dissipate silicone sheets. PDP, LED TV application power amplifier IC, image decoder IC and heat sink (housing) heat conduction. Home appliance industry microwave ovens, air conditioners (between the fan motor power IC and the housing), induction cookers (between thermistor and heat sink).

4.Product details of  Heat-dissipating silicone sheet
The Heat-dissipating silicone sheet also has the names of thermally conductive silicon film, thermally conductive silicone gasket, and soft thermally conductive pad in the industry. The heat-dissipating silicone sheet fills the air gap between the heating element and the heat sink or the metal base, forms a good heat conduction path between the heating body and the heat dissipation device, and forms the heat dissipation module together with the heat sink and structural fixtures. Their flexible and elastic characteristics enable them to cover very uneven surfaces. Heat is transferred from the separation device or the entire PCB to the metal shell or diffusion plate, thus improving the efficiency and service life of the heating electronic assembly. 100% of all raw materials for the heat sink silicone sheet come from first-line raw material manufacturers such as Japan, Germany and the United States. 1. The material is super soft, has good compression performance, good thermal conductivity and insulation performance, and the adjustable range of thickness is relatively large, suitable for filling gaps, with natural viscosity on both sides, and strong operability and maintainability; 2.

The heat-dissipating silicone sheet has the effects of sound absorption, shock absorption and sealing; 9. The heat-dissipating silicone sheet has the convenience of installation, testing, and reusability. Good convenience reduces the consumption process and corresponding costs, but also makes the return to repair and other disposal more quickly. The heat-dissipating silicone sheet is used for the control motherboard of electronic and electrical products, the inner and outer pads and foot pads of the motor, computers, security equipment, automotive machinery, automotive electronics, Netcom equipment, computer hosts, laptops, PC servers, DVDs , VCD, new energy power batteries, vehicle equipment, switching power supplies, UPS video, heating components, radiators and any materials that need to be filled and radiated modules.
