Electronic devices of high thermal conductivity requirement
Available Shapes
discs or sheets/substrates
Aluminum nitride ceramic (AlN) has excellent properties such as high thermal conductivity, high strength, high resistivity, small density, low dielectric constant, non-toxic, and thermal expansion coefficient matching with Si. It is a new type ceramic material with excellent comprehensive performance. Due to its extremely high thermal conductivity, aluminum nitride can meet the heat dissipation requirements of high-power devices such as optical communication, microwave communication, LED, and high-speed rail. It is considered to be an ideal material for the packaging of new generation semiconductor substrates and electronic devices.
Typical properties of Aluminum Nitride: ●Very high thermal conductivity ●Excellent electrical insulation(Low dielectric constant and loss) ●Low density ●Similar linear expansion coefficient with Si ●Extremely high hardness
