Electrical 96% 99% Thin Film Alumina Ceramic Substrate For Power Modules

Description of alumina ceramic substrate
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.
Specification of alumina ceramic substrate
