AIN ceramic substrates
We provides AlN ceramic substrate . AlN substrate is one of the most popular ceramic substrate which has excellent heat resistance, high mechnical strength , abrasion resistance and small dielectric loss . The surface of AlN substrate is quite smooth and low porosity . Aluminium Nitride has higher thermal conductivity , compared to alumina substrate , It is about 7 to 8 times high . AlN substrate is an excellent electronic package material . We provides AlN substrate for a wide range of applications, including thin film and thick film microelectronic , high power and high frequency circuit RF / microwave components and capacitor or resistor , contact us for more ceramic wafer product information .
