Aluminum nitride tube



AlN ceramics use heat resistant melt erosion and thermal shock resistance, can produce GaAs crystal crucible, Al evaporation pan, MHD power generation equipment, optoelectronic components, laser-semi-conductor, LED, IC products, and so on.Henka's AlN substrate can be the best solution in electronics applications where strict conditions are required, such as power modules (MOSFET, IGBT), LED packages for cooling and protecting circuits, packages and modules.

Features of ALN tube

1)High thermal conductivity of more than 170W/m. K,
2)High resistivity,
3)Low dielectric loss,
4)Good insulation,
5)Some other excellent properties
