Product Description

Ceramic Substrates for Thick-film Electronics

Product Description

The prime characteristics of the alumina ceramic substrate

1. Good smoothness/flatness to be 0.05mm

2. High-temperature resistance up to be 2000ºC

3.  Alumina offers diamond-like hardness to be HRA85

4. Chemical stability, even in almost all strong acid and alkali 

5. Both thermal conductivity and CTE are similar to silicon.

6. High electrical insulation & dielectric breakdown

7. It's anti-aging and resistant to almost all oils

8. Stable breaking strength, and less variance in good shape

9. Precise dimensions and ideal cosmetic quality

The specification of the alumina ceramic substrate
1. Material: 96% ~99.5% alumina, zirconia, silicon nitride, silicon carbide optional

2. Size: max. up to 400mm x 300mm, Thickness: range from 0.15mm to 30mm

3. Surface treatment:  Lapping, diamond-like polishing, metallization, glazed

4. The checklist of standard sizes of alumina ceramic plates in different purity.

The description of alumina ceramic substrate
Alumina ceramic substrates are formed by tape casting, dry pressed or Isostatic pressed and sintered under high temperature to be a strong and dense ceramic part. We can produce different grades of materials to custom specifications by request, in addition to custom compositions for commercial and research applications and new proprietary technologies.
In order to reach some special applications, like enhancing the insulation strength, dielectric, and precision assembly, we always proceed with these ceramic alumina plates with the secondary process with our in-housing manufacturing types of equipment, including diamond polishing, glazed surface, high precision dimensions, and super flat surface and metalized.
