Product Introduction
Aluminum nitride plate has the advantages of excellent electrical insulation, thermal conductivity, high temperature resistance, corrosion resistance, and matching with the thermal expansion coefficient of silicon. Aluminum nitride ceramic plate has become a new generation of large-scale integrated circuits, semiconductor module circuits and high-power devices. AlN ceramic plate is ideal for heat dissipation and packaging materials.
