Quality Inspection for Grinding Media Forged Steel Ball - Aluminum Nitride substrate – Sanxin Hi-Tech Ceramics Detail:
AlN substrate
Product introduction
We produce aluminum nitride substrate with excellent thermal, mechanical and electrical properties, thermal conductivity more than 170W/(m.K), dielectric constant around 8 at 1MHz, thermal expansion coefficient 4.5×10-6/℃, volume resistivity more than 10EE12 Ω.m, density 3.26g/cm3. With the rapid development of microelectronic devices, high thermal conductivity AlN substrates can be widely used in communications devices, high brightness LED, power electronics and other industries. It is thus an excellent electronic ceramic material.
