As new generation ceramic material, Alumina Nitride ceramic has become more and more popular
due to the good physical performance like high thermal conductivity, low dielectric contant and loss,
good insulating property and mechanical performance, non-toxic, high temperature resistance,
similar thermal expansion coefficient as silicon. The irregular ALN part which is machined by watch
jewel bearing & optical cold pressing technique, could fully satisfy with the field request of optical
fiber communication, high-light LED, EICC etc. .
