Material Introduction
Aluminum nitride ceramics are usually gray or off-white. It has a low thermal expansion coefficient, excellent insulation performance, heat resistance, and a thermal conductivity of more than 180W/(m.k). It is an ideal package heat dissipation material for large integrated circuits.
1. After polishing the surface finish, Ra<0.1μm.
2. The dimensional accuracy of the product in all directions is guaranteed by laser marking, and the minimum value is ±0.10mm.
3. Products with special specifications can be customized according to customer requirements.
