氮化铝陶瓷基板垫片的优点

氮化铝陶瓷基板垫片最大的优势首先在于高导热与高绝缘并存。在功率器件和电子模块中,垫片既要快速把芯片或热源的热量传导出去,又必须保持可靠电气隔离。普通金属垫片虽然导热快,但存在导电风险;普通氧化铝虽然绝缘好,但散热效率有限。氮化铝能够同时满足这两项关键需求,可显著降低器件结温,提高系统稳定性和寿命。它具备非常优秀的低热膨胀与热循环稳定性。

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.
