quality control
Material Purity
We ensure every batch of raw material is high-purity and contaminant-free, verified with X-ray, ICP, and GDMS analysis, giving you consistent performance.
Dimensional Accuracy
All targets are precisely measured with CMM, optical profilometry, and laser scanning to meet your exact size and shape requirements.
Surface Finish
We check surface smoothness and roughness using SEM, AFM, and optical microscopy to guarantee uniform thin film deposition.
Damage and Contamination Inspection
Each target is inspected for cracks, dirt, or transport damage, with visual checks, leak tests, and vacuum-sealed packaging to ensure it arrives safely and ready to use.
Our comprehensive QC ensures every sputtering target delivers stable, long-lasting performance.
certification
We manufacture under strict quality controls to international standards, including ISO 9001, ensuring reliability and consistent performance.
