Polishing AlN ceramic substrate

AlN ceramic has following properties

  • High thermal conductivity (theoretic value 320W/m.K)
  • High electricity resistance
  • Low coefficient of heat expansion(4.5X10-6ºC)Good march with Si(3.5~4×10-6ºC) and GaAs(6×10-6ºC) 
  • Excellent electricity properties(Dielectric constant, dielectric loss, bulk resistivity, dielectric strength). 
  • Good mechanic properties 
  • Excellent corrosion resistance 
  • Good optical transmission propertyAlN ceramic has become an ideal material for heat radiation and package in industries of large
