The description of alumina ceramic sheets
We have been making alumina (Aluminum oxide, Al2O3) ceramic sheets
for over 12 years under rigorous quality control with carefully
selected high purity ceramic materials ranging from 95% to 99.8%.
All these alumina substrate offer extraordinary properties of electrical insulation, thermal
conductivity, breaking strength, and high-temperature resistance.
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. Also, it can play a critical role in the sintering
process which works as an alumina ceramic setter.
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.
