Polished Aluminum Nitride Substrate

Polished Aluminum Nitride Substrate

Features: 1. The surface undergoes high-precision grinding, resulting in high surface flatness, good smoothness, and low roughness.

Dimensions: The standard size of the ground aluminum nitride substrate is 120mm x 120mm x 1mm, but customization is also available upon request.

Applications: High-precision grinding processes for hard drive heads, solar cells, LED packaging, mechanical parts, and optical equipment.

Features: It has high mechanical strength, high heat resistance, and low cost.

Dimensions: The standard size of the sintered aluminum nitride substrate is 120mm x 120mm x 1mm, and it can also be customized according to customer requirements.

Applications: High-temperature tools, molten metal containers, solar cells, and other fields.
