Specification of ceramic substrates

1. Shaping methods: tape casting, dry pressing, isostatic pressing, hot pressing and so on.

2. Material options: aluminum oxide, zirconium oxide, silicon carbide, aluminum nitride and so on

3. Typical thickness: 0.25 mm, 0.30 mm, 0.40 mm, 0.50 mm, 0.635 mm, 0.80 mm, 1.0 mm, 1.2 mm

4. Dimension capability: min. thickness to be 0.15 mm, max. length and width to be 400 mm x 300 mm

5. Dimensional tolerance : thickness ± 0.05 mm, length ± 0.20 mm, width ± 0.20 mm

6. Surface treatment: polishing to mirror - like surface, metallizing for ceramic to metal bonding

7. Secondary process : laser cutting, fine grinding, high precision CNC machining and so on

Main features of alumina ceramic substrates

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(℃) 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. More 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 various harsh conditions

8. Low density, over 3.65 g /cm3, with light weight, it's benefit to design the device more lighter.

Description of alumina ceramic substrates

We have been producing alumina (Al2O3) ceramic substrates for over 15 years under rigorous quality control with carefully selected high purity ceramic materials that ensure stable and consistent quality and excellent properties.
These alumina substrates have extraordinary properties of electrical insulation, thermal conductivity, breaking strength and high-temperature resistance. Furthermore, one of the unique properties is its surface roughness. We can provide the Ceramic Substrate which is excellent in adhesion with a thin film and thick film metallization due to fine particles.
The main forming method we use is tape-casting, Isostatic pressing. We are dealing with a variety of selection of thickness from 0.15 mm to 20 mm, whatever, it's prototyping needs, or mass production for cost down. We could offer you an ideal solution.

Application of alumina ceramic substrates

Alumina ceramic substrates are widely used in power modules, LED lighting, power semiconductor, automotive electronics, DBC ceramic substrate

Application of ceramic substrate

Standard size of alumina ceramic substrates with stock

Alumina Ceramic substrates


1. All big ceramic alumina substrate in above list can be cut to small size sheet, small size plate.

2. Some of above alumina ceramic substrates are made of 96% purity aluminium oxide, or 99%.

3. Other long-side and thickness can be customized, max. size is up to be 400 mm, min. thickness is small to be 0.15 mm.
