Product Description

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.

Aluminum Nitride Ceramic Substrates has a well equipped and modern tool room dedicated to the manufacture and maintenance of customers tooling. By keeping this process in house we are able to keep not only simple but extremely complex tooling costs to a minimum, coupled with shorter lead times.
