Aln aluminum nitride ceramic round disc substrate for semiconductor

Among the existing ceramic materials that can be used as substrate materials, silicon nitride ceramics have the highest bending strength, good wear resistance, the best comprehensive mechanical properties, and the smallest coefficient of thermal expansion. Aluminum nitride ceramics have high thermal conductivity, good thermal impact resistance, and good mechanical properties at high temperature. It can be said that from the point of view of performance, aluminum nitride and silicon nitride are the most suitable materials for electronic packaging substrate
