* High thermal conductivity
* Similar linear expansion coefficient with Si
* Excellent electrical insulation
* Low dielectric constant and loss

The aluminum nitride (AlN) ceramic has high thermal conductivity (5-10 times as the alumina ceramic), low dielectric constant and dissipation factor, good insulation and excellent mechanical properties, non-toxic, high thermal resistance,chemical resistance, and the linear expansion coefficient is similar with Si. As a new generation of ceramic material,AlN ceramic attracts more and more attention. In the leading level of domestic enterprises’, the quality of our company AlN ceramic substrate reaches the international advanced level. It is widely used in communication components, high power led, power electronic devices and other fields.
