Aluminum nitride ceramic heating plate

Aluminum nitride ceramic heating plate is a high-performance ceramic heating element, mainly made of aluminum nitride (AlN) material. Aluminum nitride has extremely high thermal conductivity, and its thermal conductivity can reach 70-180 W/m · K, which is much higher than that of traditional alumina ceramics. In addition, it also has excellent electrical insulation, low coefficient of thermal expansion, high mechanical strength and good chemical resistance. These characteristics make aluminum nitride ceramic heating plate excellent in high temperature, insulation and heat dissipation, and is widely used in scenarios with extremely high thermal management requirements.
The heating plate typically consists of an aluminium nitride ceramic substrate and embedded heating elements such as nickel, tungsten or molybdenum wires. By energizing the heating element, heat is generated, and the aluminium nitride ceramic is able to efficiently and evenly transfer heat to the entire surface. It also has the ability to heat up quickly, with some products reaching 600 ° C in 5 seconds, while also cooling quickly to adapt to the needs of fast temperature-changing processes.

Application field
The application range of aluminum nitride ceramic heating plates is very extensive, mainly concentrated in the following areas:

1. Semiconductor manufacturing: In the process of wafer processing, chip packaging, etc., aluminum nitride ceramic heating plates are used to precisely control temperature to ensure high-quality chip production.
2. Electronic equipment: used for heat dissipation and heating of high-power electronic devices, such as LED industry, automotive electronic function modules, etc.
3. Vacuum coating: In the vacuum coating process, the aluminum nitride ceramic heating plate can quickly heat up and evaporate the coating material.
