aln/aluminum nitride ceramic bars features:
application
high-power circuits, rf and microwave circuits , gaas crystal crucible, al evaporation pan, mhd power generation equipment
product introduction
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.
ain 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.
note:
surface roughness can be reached 0.08 μm after polished.
size tolerance can be controlled in ±0.050mm with laser machined.
special specifications can be supplied upon requests.
