Aluminum Nitride Ceramic Substrate Surface Precision Polishing Processingmerits

Aluminum nitride ceramic substrates with precision polished surfaces have high thermal conductivity and electrical insulation, and can therefore be used in a variety of electronic devices. Aluminum nitride has a thermal conductivity of 170W / (mk), which is 5-8 times higher than that of alumina ceramics.

Aluminum Nitride Ceramic Substrate Surface Precision Polishing Process

Advantages of Aluminum Nitride Ceramic Substrates

Aluminum nitride ceramic substrate has high thermal conductivity, low coefficient of expansion, high strength, high temperature resistance, chemical resistance, high resistivity, low dielectric loss and other characteristics, which makes it an ideal high temperature resistant insulating ceramic product. Aluminum nitride ceramics can replace toxic beryllium oxide ceramics and are widely used in the electronics industry.

Applications of Aluminum Nitride Ceramics

Aluminum Nitride (AlN) ceramics have high thermal conductivity and electrical insulation, so they can be used in a variety of electronic devices. Aluminum nitride has a thermal conductivity greater than 170W/(mk), good resistance to thermal shock, and can be used in high temperature environments up to 2200℃. Therefore, aluminum nitride ceramic products are ideal for many industries, such as:

  • Radiators and heat sinks
  • Electronics Packaging Substrates
  • Substrates and insulators for microelectronic and optoelectronic devices
  • Laser Thermal Management Components
  • electrical insulation
  • Molten Metal Fixture

Basic Properties of Aluminum Nitride Ceramics

Aluminum Nitride (AlN) is a covalently bonded compound, atomic crystal, diamond-like nitride, hexagonal crystal system, fibrillated zincite crystal structure, non-toxic, white or off-white.

  • High thermal conductivity (>170W/m-K), close to BeO and SiC, more than 5 times that of Al2O3;
  • The coefficient of thermal expansion matches that of Si and GaAs;
  • Various electrical properties (dielectric constant, dielectric loss, body resistivity, dielectric strength) are excellent;
  • Good mechanical properties, higher flexural strength than Al2O3 and BeO ceramics, can be sintered at atmospheric pressure;
  • It can be produced by casting process and is a promising substrate and packaging material for high power integrated circuits.
