Properties of Al2O3 Substrate

 

1. Good smoothness, or flatness with less porosity, and excellent in adhesion with thin film and thick film materials.

 

2. Small variance in outline, plate thickness, and slit pitch, mininmal warpage, bending, and undulation.

 

3. Superior mechanical strength, good pressure and impact resistance, not easy to break or wear.

 

4. Excellent in thermal shock resistance, high thermal conductivity and coefficient of thermal expansion similar to that of silicon.

 

5. Excellent oil and chemical resistance.

 

6. Excellent in insulation properties, high breakdown voltage,  and small dielectric constant.
