BeO Ceramics

Beryllium Oxide Substrate

Beryllium oxide ceramic substrate is made of beryllium oxide powder as raw material and sintered at high temperature after forming. It has excellent thermal conductivity, low dielectric constant and dielectric loss, reliable insulation performance, high temperature resistance and corrosion resistance. It is widely used in microwave devices, communication devices, high brightness LED, power electronic devices, especially various high-power devices and integrated circuits. The high thermal conductivity of beryllium oxide ceramic substrates can provide a strong guarantee for their stable operation.

Properties of BeO Substrate

1. With excellent thermal conductivity, up to 310W/(℃*m), which is around 10 times of alumina substrate. It has high temperature resistance and thermal shock resistance is good.

 

 

 

2. Good electric insulation, high breakdown voltage, large current carrying capacity.

 

 

 

3. Low dielectric constant, which is around 7, and the dielectric loss is very low, which can reduce the energy loss during signal transmission.
