Product Description

Alumina Plate Panel Board Ceramic Substrates for DBC DPC PCB
 

The specification

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.

The description of alumina ceramic substrate

Product Description

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.

The typical application of ceramic substrates

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