Customized Aluminum Nitride ALN ceramic wafer
1. High thermal conductivity
2. High flexural strength, high temperature
3. Good electrical insulation

Introduction                                                                                                                                       

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,which is widely used in communication components, high power led, power electronic devices and other fields.Special spec products can be produced upon requests.
