Aluminium nitride substrates<\/a>\u00a0is a new generation of high-performance ceramic substrate. It has high thermal conductivity (theoretical value is 319w \/ m.k, and the thermal conductivity is greater than 140W \/ m.k), low dielectric constant (8.8) and dielectric loss (~ 4) \u00d7 104) and the coefficient of thermal expansion (4.4 \u00d7 10-4 \/ \u2103), chemical composition Al 65.81%, N 34.19%, specific gravity 3.261g\/cm3, white or gray white, single crystal colorless and transparent, sublimation and decomposition temperature of aluminium nitride substrates is 2450 \u2103 at atmospheric pressure.<\/p>\nAluminium nitride ceramic has high thermal conductivity, good electrical properties, thermal expansion coefficient close to Si chip, high strength, high temperature resistance, chemical corrosion resistance, high resistivity, low dielectric loss and non toxicity. Aluminium nitride is an ideal material to replace BeO ceramics and an ideal heat dissipation substrate and packaging material for large-scale integrated circuits.<\/p>\n
Aluminium nitride substrates is mainly used as high-performance substrate materials and packaging materials in high-density hybrid circuits, microwave power devices, power electronic devices, optoelectronic components, semiconductor refrigeration and other products. It is widely used in communication devices, high brightness LED, power electronic devices and other industries.<\/p>","protected":false},"excerpt":{"rendered":"
