Aluminum Nitride Substrates
Boron Carbide Parts China, Advanced Ceramics Division supplies high-quality and competitive price advanced Aluminum Nitride Substrates.
Aluminum Nitride Substrates, AlN Substrates
Boron Carbide Parts China, advanced ceramics division is a leading supplier of aluminum nitride ceramic materials. We supply aluminum nitride substrates for semiconductors.
Aluminum nitride (AlN) is a new type of ceramic material with excellent comprehensive properties. It has excellent thermal conductivity, reliable electrical insulation, low dielectric constant and dielectric loss, non-toxic, and a coefficient of thermal expansion compatible with silicon. The series of excellent characteristics are considered to be the ideal materials for highly concentrated semiconductor substrates and electronic device packaging.
