25x25x2mmt AlN Ceramic Substrate plates with High Thermal
Conductivity 200w
AlN Introduce
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.
Our cooperating factory can applied the casting-tape process for
the manufacturing of alumina substrate. With good thermal
conductivity, insulation, thermal shock resistance, well resistance
and anti-acid and alkali etc., our ceramic substrates can be used
in thick-film hybrid integrated circuits (HIC), LED ceramic
radiating base, power module, semiconductor devices and other
fields.

Polishing Service
Our AlN substrate can be polished(single and double polish) by the
advanced machine which imported
from abroad. Ceramic substrate surface roughness can reach to 1nm
without porous after being polished.
It is perfectly suitable for the device application of small spec,
high precision , wiring density and good stability.
