How to use thermal silica gel


Thermally conductive silicone is a high-end thermal compound that does not solidify and does not conduct electricity. It avoids risks such as short circuits. Its high bonding performance and superior thermal conductivity are currently the best for CPU, GPU and heat sink contacts. Thermal solution.
Performance advantages
1, the range of thermal conductivity and stability
2, the structural tolerance of the structure is bridged, reducing the process tolerance requirements of the heat sink and heat dissipation structural parts
3, EMC, insulation properties, thermal silica gel has high thermal conductivity, excellent thermal conductivity, good electrical insulation, wide temperature, good stability, low consistency and good construction performance.
How to use
The main purpose of selecting a thermal conductive silicone sheet is to reduce the contact thermal resistance generated between the surface of the heat source and the contact surface of the heat sink member. The heat conductive silicone sheet can well fill the gap of the contact surface, and the air is squeezed out of the contact surface, and the air is hot. The conductor will seriously hinder the transfer of heat between the contact surfaces; it is supplemented by the heat-conducting silica gel sheet to make the contact surface better contact, and the face-to-face contact and the temperature reaction can achieve the smallest temperature difference. .
The thermal conductivity of thermal silica gel is relative, although its thermal conductivity is better in flexible materials, generally in the range of 0, 6-1, 5W / (m · K), a few performance may be higher, but not more than 2W/(m·K). It is higher than water 0.5, vulcanized rubber 0.22, Vaseline 0.184, etc. But there is no advantage with the 1.5W/(m·K) of cement. Almost all metals have much higher thermal conductivity than thermal silica. The thermal conductivity of gold, silver and copper in the metal is between 330 and 360, and the thermal conductivity of aluminum is around 200. The thermal silica gel itself is not a good conductor of heat. The role of the thermal silica gel is to fill the gap between the heat source and the heat sink. Therefore, the use of thermal silicon is as thin as possible. It can apply 0.1-0.5 mm thick thermal silica to fill the gap, and the effect is much better than the 1 mm thick silica gel.
Application range
The thermal conductive silica gel can be widely applied to various electronic products, the contact surfaces between the heating elements (power tubes, thyristors, electric heating stacks, etc.) and the heat dissipation facilities (heat sinks, heat sinks, housings, etc.) in the electrical equipment. It acts as a heat transfer medium and is resistant to moisture, dust, corrosion and shock. It is suitable for surface coating or integral potting of various microwave devices such as microwave communication, microwave transmission equipment, microwave dedicated power supply, and regulated power supply. This kind of silicon material provides excellent thermal conductivity for generating hot electronic components. Such as: transistors, CPU assembly, thermistor, temperature sensor, automotive electronic components, car refrigerators, power modules, printer heads, etc. K thermal silica gel sheet.
Packaging and storage
1, 100ml / support, 100 / box and 300ml / support, 25 / box two kinds of packaging.
2. The storage period is 12 months (8-25 ° C).
3, belonging to non-dangerous goods, can be transported as general chemicals, be careful to leak during transportation!
4. If the storage period is exceeded, it should be confirmed whether there is any abnormality before use.
