Product Description

Polished Aluminum Nitride (ALN) Ceramic Substrate

 

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.

 

 

PRODUCT PERFORMANCE

- High thermal conductivity, high flexural strength, high temperature

- Good electrical insulation

- Low dielectric constant and loss

- Able to be laser drilled, metallized, plated and brazed

*Various metalized processing is available (Thin film, Thick film, DBC, AMB, DPC, etc.)
