Product Description

Laser Cutting 96% Al2o3 Ceramic Alumina Substrate for Electronics

 

Product Description

Alumina is a most popular technical ceramic for making ceramic substrate for electronics because the advantages of high resistivity,outstanding thermal conductivity, good mechanical and dielectric strength, also chemical stability.

The main shaping method is tape casting, it's easy to obtain dense ceramic body with high-efficient productivity. In common case, 96% alumina ceramic substrate is for thick-flim technology, and above 99.5% alumina ceramic substrate is for thin-flim circuit which require a more rigorous quality for the grain size, the surface finish of ceramic substrates. Currently, we  have been making both electronic substrates for ages.
