We focus on manufacturing alumina (Aluminum oxide, Al2O3) ceramic substrate for over 14 years under rigorous quality control with carefully selected high purity ceramic materials ranging from 95% to 99.6%.
High thermal conductivity | Up to 31 W/m.k at room temperature |
Low density | Over 3.75 g /cm3, with light weight |
Good thermal shock | Greater than 800 T(ºC) without any cracks |
Good surface roughness | Roughness to be Ra0.2 or better, and warpage less than 0.3% |
Anti-aging | Resistance to oxidization and free of rusty forever |
Ideal electrical properties | Dielectric Strength≥15 KV/mm, Dielectric Loss Angle ≤3 ×10 -4, Dielectric Constant : 9.4 MHz |
Heat dissipation | Much quicker than tradditional cooper and aluminum metal materials |
We have sufficient safety stock for standard ceramic substrate, it's easy to meet your quick and flexible delivery requirement. Refer to the checklist of alumina ceramic substrate in stock.

Remark:
We offer ceramic substrates in selection of materials, mainly including aluminum nitride, silicon nitride and zirconium oxide and so on. All these substrates can be in-house lapped, polished and metallized.
Remark:
The attached packaging solution is our standard one. In common case, the internal configuration will be customize designed per customers' specification of ceramic substrate.
