Several common applications of thermally conductive silicone in the electronics industry

Date of release:2020-05-21 Author:Cosworth Click:

Thermally conductive silicone is vulcanized into high performance elastomer by cross-linking and curing caused by the release of low molecules through the condensation reaction of water in the air. It has excellent resistance to cold and heat alternation, aging resistance and electrical insulation performance. It also has excellent moisture resistance, shock resistance, corona resistance, leakage resistance and chemical medium resistance. It can be used continuously from -60 to 280°C and maintain its performance. It does not swell and has good adhesion to most metal and non-metal materials, and can have good heat transfer to electronic components.      

The heat-conducting silica gel widely used in electronic appliances is actually a compound latex, the composition of silicone oil as the main raw material, and by the electrical insulation properties and thermal conductivity of the compound formulated from good heat dissipation, heat-conducting silica gel can be widely coated in a variety of electronic products, electrical equipment between the contact surface of the heating body, the role of heat transfer medium and moisture-proof, dust-proof corrosion-resistant shockproof performance. Suitable for microwave communication, microwave transmission equipment, microwave power supply, voltage stabilization power supply and other microwave devices surface coating or overall potting.

Washing machines, electric showers and other household appliances exposed to the housing of the various fixed screws, if the use of thermally conductive silicone will be screw holes coated touch closed, so that not only put to prevent the screws from rusting later disassembly and maintenance difficulties, but also to make the screws play a good electrical insulation protection role.

In some TV antenna connection head, outdoor power line connection head, communication line and indoor connection line, closed-circuit television junction box, etc. due to long-term exposure, easy to cause contact between the line and the line of the junction head and oxidation corrosion, if the junction head after the appropriate amount of drops coated with some heat-conductive silica gel, and then wrapped with tape, so that it can effectively maintain long-term not be oxidized, but also can play a role in addition to The effect of moisture and corrosion.

In some easy to produce heat electronic high-power components, such as color TV line drive tube, amplifier amplifier tube, electronic ballast power tube, voltage regulator module, and high-power tube and heat sink, computer CPU chip and heat sink between the body, when in the component surface or in the component and heat sink mutual contact layer between the appropriate amount of injection of some heat-conductive silica gel can effectively improve the actual effect of heat dissipation.
