$1.00 – $4.50
Innovacera Ceramic Thermally Conductive Interface Pads are designed to provide a preferential heat-transfer path between heat-generating components, heat sinks, and other cooling devices. The pads are used to fill air gaps caused by imperfectly flat or smooth surfaces which should be in thermal contact. The pads are made of ceramic materials such as alumina ceramic and aluminum nitride, which help in providing enhanced thermal conductivity and excellent insulation performance. Typical applications include Power Devices, Integrated Circuit (IC) chip packaging heat conduction, MOSFET Transistor, IGBT Transistor Heat Sink, MOS Transistor, heat sink interface, LED board Thermal Interface Material (TIM), Chip ON Film (COF) heat conduction.
A ceramic heat sink is a device that dissipates heat-dissipating electronic components in an electrical appliance.
The whole structure of the ceramic heat sink increases the heat dissipation area in contact with the air, which greatly enhances the heat dissipation effect, and the heat dissipation effect is better than that of the super copper and aluminum.
Ceramics are insulated, resistant to high temperatures, oxidation, acid and alkali, cold and thermal shock, and low coefficient of thermal expansion, ensuring stability in high and low temperatures or other harsh environments.
Ceramics can withstand high current, can be high voltage, can prevent leakage breakdown, no noise, will not generate coupling parasitic capacitance with power tubes such as MOS, and thus simplify the filtering process.
Aluminum nitride ceramic thermal insulator pads are ceramic materials with outstanding properties such as high thermal conductivity and high electrical resistance. In addition, it is featured advantages such as high hardness, corrosion resistance, low dielectric constant and dielectric loss, and low CTE. Aluminum nitride ceramics have excellent thermal conductivity (7-10 times that of alumina ceramics), as the thermal expansion coefficient of silicon is similar, as a new generation of ceramic materials, more and more people pay attention to it.
Ceramic Thermal Pads Installation Steps:
①Clean the target surface: Clean the dust or stains on the surface of the object to be installed, and then align the hole position of the ceramic insulating sheet;
②Power tube bonding: Stick the power tube on the ceramic insulating sheet;
③Fixed the insulation sheet: Use screws to fix the power tube and ceramic insulating sheet on the installation object.
