    Product details Technical specification

    Why do we use AlN ceramic PCB?

    At present, high-power IC materials are generally aluminum oxide or BeO ceramics. Although BeO has excellent comprehensive properties, its high production cost and toxic disadvantages limit its application and promotion. However, the thermal conductivity of Al2O3 substrate is low and the thermal expansion coefficient does not match with Si. The performance, cost and environmental protection can not meet the requirements of high-power electronic devices. The aluminum nitride ceramic PCB produced by ipcb company can solve the above problems.


    Aluminum nitride ceramic has excellent comprehensive properties, which is a new generation of advanced ceramics which has been widely concerned in recent years. It has a wide range of application prospects in many aspects, especially its high thermal conductivity, low dielectric constant, low dielectric loss, excellent electrical insulation, thermal expansion coefficient matching with silicon and non-toxic, which makes it become a high-density, high-power and high-speed integrated PCB Ideal material for packaging substrate.

    AlN ceramic PCB

    Among a series of important properties of AlN, the most significant one is the high thermal conductivity. Its main mechanism is: through lattice or lattice vibration, that is, by means of lattice wave or thermal wave. AlN ceramic is an insulating ceramic material. For insulating ceramic material, heat energy is transmitted by atomic vibration, which belongs to phonon heat conduction. Phonons play an important role in its heat conduction process. Theoretically, the thermal conductivity of AlN can reach 320W (m · K), but the thermal conductivity of AlN ceramic PCB can not reach the theoretical value due to the impurities and defects in AlN. The impurities in AlN powder are mainly oxygen, carbon, and a small amount of metal ions impurities, which produce various forms of defects in the lattice. The scattering of phonons by these defects will lead to thermal conductivity. Even so, AlN ceramic PCB has the highest thermal conductivity on the market.
