Aln Aluminium Nitride Ceramic for Elelctronic Products With High Heat Dissipation
Aluminum nitride ceramic substrate, high thermal conductivity, low coefficient of expansion, high strength, high temperature resistance, chemical resistance, high resistivity , low dielectric loss, is the ideal LSI heat dissipation board and packaging materials.
ALN ceramics use heat resistant melt erosion and thermal shock resistance, can produce GaAs crystal crucible, Al evaporation pan, MHD power generation equipment and high temperature turbine corrosion resistant parts, using its optical properties can be used as an infrared window.
Aluminum Nitride (ALN) is a ceramic material with outstanding properties such as high thermal conductivity and high electrical resistance. In addition, it is featured with advantages such as high hardness, corrosion resistant, low dielectric loss and low CTE.
It is widely used in the semiconductor, electronics, electrical and other industries.

Polishing processing service:
Our AlN substrate can be polished(single and double polish) by the advanced machine which imported from abroad. Ceramic substrate surface roughness can reach to 0.03-0.05um without porous after being polished. It is perfectly suitable for the device application of small spec, high precision , wiring density and good stability.
