Laser processing service:
Through laser machine scribing, cutting, and drilling, we can process AlN substrate with high accuracy and absolute consistency upon customers'request.
Polishing processing service:
Our AlN substrate can be polished(single and double polish) by the advanced machine which imported from abroad. Ceramic substrate surface roughness can reach to 0.03-0.05um without porous after being polished. It is perfectly suitable for the device application of small spec, high precision , wiring density and good stability.
