Refractory Machinable Custom 99.5% Alumina Ceramic Plate for
Industrial
Description of alumina ceramic plate
We have been producing alumina (Al2O3) ceramic substrates for over
15 years under rigorous quality control with carefully selected
high purity ceramic materials that ensure stable and consistent
quality and excellent properties.
These alumina substrates have extraordinary properties of
electrical insulation, thermal conductivity, breaking strength and
high-temperature resistance. Furthermore, one of the unique
properties is its surface roughness. We can provide the ceramic
substrate which is excellent in adhesion with a thin film and thick
film metallization due to fine particles.
The main forming method we use is tape-casting, we are dealing with
a variety of selection of thickness from 0.25mm to 20mm. Besides,
we support prototyping case to mass production.

The advantages of alumina ceramic substrate:
1. High thermal conductivity, up to 24 W/m.k at 25℃
2. Good thermal shock resistance, greater than 220 T(℃)
3. Good surface roughness, flatness to be 0.05mm
4. High dielectric strength, low dielectric constant and dielectric
loss.
5. Laser cutting or precision machining cutting makes tight
tolerance.
Typical applications of alumina ceramic substrate:
LED packages, Power modules, Substrates for chip resistors, HIC
substrates for heat dissipation, FAX substrates for thermal printer
head, Substrates for automotive parts, Substrates for general thick
film application, Substrates for sensor parts, Substrates for
electronic devices
