Product Description
Introduction of the 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 ceramic substrate
communication components, high power led, power electronic devices and
other fields.Special spec products can be produced
upon requests.
Product Performance of the ceramic substrate:
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
