Quality Assurance & Handling Instructions
Silicon wafer acceptance check and testing procedures
Important Handling Guidelines
Our silicon wafers are manufactured through precision cutting, polishing, and cleaning of high-purity single crystals under strict quality control systems.
  • Products are fragile and shipped with adequate protective packaging and "fragile" labeling
  • Handle with care upon receipt and inspect outer carton condition
  • Document packaging condition with photos before removing products
  • Open vacuum packages only in clean room environments
  • Report any transit damage immediately with photographic evidence
