Thin Insulator Al2o3 Substrate Alumina Ceramic Sheet For Pcb Use , High Dielectric Strength

Thin Insulator Al2o3 Substrate Alumina Ceramic Sheet For Pcb Use , High Dielectric Strength

High temperature thin insulator alumina ceramic substrate for pcb use

1. Description 

Al2O3 ceramic substrate is the most popular ceramic substrate, with excellent heat

resistance, high mechanical strength , abrasion resistance and small dielectric

loss.The surface of alumina substrate is quite smooth and low porosity.99.6%

alumina substrate is suitable for thin film device, 96% alumina substrate is suitable for thick film device application .

2.Alumina ceramic  advantages:

1. The main material of our products is high purity quality alumina, which cause no negative effective effect to the grinded material.
2. High density and hardness, impact resistance, low loss rate, smooth surface and no contamination to product.
3. With high grinding efficiency which can reduce grinding time to reduce energy cost and being good for environment protection.
