Beryllium Oxide (BeO) Ceramics, which is commonly referred to as beryllia ceramics. BEO ceramic substrates are made of more than 99% beryllium oxide ceramics. The ceramic substrate is based on the electronic ceramic, with the membrane circuit element outside and the fitting element to form a support base for the sheet material. Beryllium Oxide Ceramic substrates thermal conductivity is more than 230 W/Mk, so it is widely used for Advanced LED Ceramic Modular Technology which requests very high thermal conductivity.
Beryllium oxide ceramic substrate advantages:
- High melting point
- Low dielectric constant
- High electrical resistivity
- Thermal shock resistance
- Easy and effective metallization
- More consistent heat dissipation
- Low coefficients of thermal expansion
- Better uniformity of crystalline structure
- Superior thermal conductivity(equivalent to aluminum)
- More durable in semiconductor chamber cleaning environments
Beryllium oxide ceramics are one of the most important and necessary basic materials for electric vacuum devices, power electronic modules, especially high-power microelectronic devices. The application is as below:
