Definition

ISO 9001 is the baseline quality management certification for PCB manufacturers. It establishes criteria for a quality management system ensuring consistent delivery of products meeting customer and regulatory requirements. The standard requires documented procedures, systematic quality checks, defect prevention, and continuous improvement. Virtually all professional PCB procurement requires ISO 9001 certification as the minimum. It doesn't guarantee technical capability, but it ensures the fabricator has controlled processes and traceability. Current version is ISO 9001:2015.
