Product Description
We focus on producing alumina (Aluminum oxide, Al2O3) ceramic substrate for over 14 years under rigorous quality control with carefully selected high purity ceramic materials ranging from 95% to 99.6%.
All these ceramic substrates offer extraordinary electrical, thermal and mechnical properties, especially the outstanding thermal conductivity, similar coefficient of thermal expansion thermal to Si. Furthermore, one of the unique properties is its superb surface roughness to be Ra0.2 which results in excellent adhesion strength with a thin film and thick film metallization due to fine particles, it's an ideal material for a wide range of circuit board.
The regular forming methods we use include tape-casting, isostatic pressing, dry pressing. We are dealing with a variety of selection of thicknesses from small-size to large-size capability. With our comprehensive types of manufacturing types of equipment, we have the capability from prototyping to mass production in the short term.
Typical Applications
Remark:
Alumina ceramic substrates are widely used in high powder modules, intergrated semconductor cirucits and photovaltaic technology and LED lighting. The ideal thermal conductivity and quick heat dissipation performance is much benefit to the realibity and sevice life.
