Characteristics and applications of various types of thermal materials

Characteristics and application of various types of thermal conductive materials: The compression resilience of thermal conductive silicone sheets has good thermal conductivity and high level of withstand voltage, which meets the demand for thermal conductive materials in the electronic industry. It is an alternative to thermal grease and thermal mica plus mica. The best product for the yuan cooling system. Under the same conditions, the thermal impedance is smaller than other thermal materials. With soft, clean, non-polluting and radioactive, high insulation properties, glass fiber reinforcement provides good mechanical properties, can prevent puncture, shear resistance, tear resistance, and can be equipped with thermal pressure sensitive adhesive. This type of thermal conductive film product is easy to install and facilitates automated production and product maintenance. It is a new material with great process and practicality. Flexible thermal silica gel pad A thick thermal conductive gasket specially designed for the transmission of heat through the gap. It can fill the gap and complete the heat transfer between the heat generating part and the heat radiating part, and at the same time, it can also absorb, insulate and seal. It can meet the design requirements of miniaturization and ultra-thinness of equipment.

The thermal conductivity of the thermal conductive silicone sheet is not only related to the thickness of the thermal conductive material, but also related to the application area of the thermal conductive material. Due to the structural relationship of the thermally conductive material, in general, the thermally conductive material is also related to the magnitude of the pressure applied. The pressure is high and the thermal conductivity will be strong. Typically, thermal materials are subjected to pressures between 5 and 100 psi, and most radiators do not exceed 250 psi. Alumina thermal conductive rubber: good thermal conductivity, beautiful appearance, widely used in the heat dissipation of communications and other products. Boron nitride thermal conductive rubber: excellent thermal conductivity, suitable for high-power device heat dissipation, under the same conditions, compared with ordinary thermal conductive materials, the device temperature can be lower than 20 °C. Application Note: The above several types of thermal insulation materials are made of silicone rubber. When applying, the heat dissipation surface should be smooth and clean, and there should be no burrs to avoid puncturing the rubber sheet and destroying the insulation. The smaller the thermal resistance of the thermally conductive material, the shorter the entry stability time and the lower the stable temperature. The application of the thermal insulation sheet is not necessarily supplemented by other materials.

The thermal conductive silicone adhesive can also be used as a thermal conductive adhesive, which not only has the effect of heat conduction, but also is a good material for bonding and sealing potting. The heat of the heat-generating component is conducted by filling the contact surface or the can body. Thermally conductive and insulating potting compound is suitable for potting of electronic components with high heat dissipation requirements. The adhesive has good thermal conductivity after curing, excellent insulation, excellent electrical properties, good adhesion and good gloss.

Thermally conductive phase change materials are primarily used in high performance microprocessors and heat generating components that require very low thermal resistance to ensure good heat dissipation. The thermally conductive phase change material undergoes a phase change at about 45 to 50 °C. And under the action of pressure, it flows into and fills the irregular gap between the heating element and the radiator, and squeezes out the air to form a good heat conduction interface.

Applications: Microprocessors, memory modules and cache chip DC/DC converters, IGBTs and other power modules Power semiconductor devices, solid state relays, bridge rectifier phase change pads are packaged in rolls and are 100 feet long. The standard width is 25.4 mm and is available in a variety of sizes.
