Main characteristics of alumina ceramic substrate
1. High thermal conductivity, up to 25 W/m.k at room temperature and low coefficient of thermal expansion
2. Good thermal shock resistance, greater than 220 T(ºC) and refractory with high - temperature resistance
3. Good surface roughness, flatness to be 0.05 mm and very smooth texture with super tiny grain size
4. High dielectric strength, high electrical resistivity, low dielectric constant, and dielectric loss.
5. Laser cutting or precision machining cutting makes tight tolerance for precision fitting easily
6. Quicker heat dissipation than cooper and aluminum metal materials and increase the service life
7. Anti-aging, resistance to oxidization and free of rusty forever, also chemical stability to in harsh conditions
8. Low density, over 3.65 g /cm3, with lightweight, its benefits to design the device lighter.
