Aluminum Nitride Ceramic Heating Element

Image
AluminAluminum Nitride Ceramic Heating Plate Characteristics The heater can have a built-in K-type thermocouple, so it has good temperature sensing characteristics, improves its responsiveness to rapid heating and cooling, and can be used safely. Fast heating and cooling The aluminum nitride substrate with high thermal conductivity car be used to achieve rapid heating and cooling, and the therma expansion rate can be used according to the material properties to design under high power density, so it can also be used for rapio heating and cooling (both 150'c/ sec) temperature cycle. Excellent electrical performance Excellent insulation and voltage resistance at high temperatures. Thermal Properties Thermal Conductivity 150 (W/mK) Thermal Expansion Coefhcient 4.5 (ppm/c) Physical Properties Density 3.2 (g/cm3) Hardness 1050(Hv@500g) Flexure Strength >250 (MPa) Electrical Characteristics Voltage 12V-240V Leakage <1mA Capacitivity 8.9 Insulation Voltage 15KV/mm

What Is Ceramic Heat Sink?

Image
Components of modern technology products, such as computer chips or light-emitting diodes, generate more and more waste heat during operation, and generally existing heat dissipation devices used to assist heat dissipation components usually include at least a metal heat sink and a fan conducts the waste heat from the operation of the heating element through the heat sink to remove it by air convection, and uses the fan to forcibly accelerate the convection of the air around the heating element to achieve the effect of rapid heat removal. However, the heat transfer coefficient of existing metal heat sinks is not very good. Therefore, heat sinks made of ceramic materials with better heat transfer characteristics appear on the market in order to achieve better heat dissipation effects. Ceramic heat sink classification There are aluminum oxide heat sinks, aluminum nitride heat sinks, and silicon carbide heat sinks . There is the performance comparison between the usual heatsink VS ceramic...

Metallized Ceramic Insulators

  INNOVACERA’s  metallized ceramic insulators  are made by ceramic combined with thick metal films through a metallization process. This combination of ceramic and metal results in insulators that can withstand harsh conditions and provide electrical isolation when needed.
