NorCal Quality Assurance

Nor-Cal Products, Inc dba Pfeiffer Vacuum Valves & Engineering is an ISO 9001:2015 Certified company that has also received SSQA Preferred Supplier status from two large semiconductor equipment manufacturers. Our Quality Management System also supports MIL-Q-9858 and MIL-I45208 Quality Program Requirements and ANSI/ASQC C1 General Quality Program Requirements. Ongoing efforts are made to control and improve manufacturing processes. Periodic defect analysis results in process improvements with narrower acceptable limits on subsequent production runs. Our calibration procedures meet MIL-STD-45662A, and our QA sampling plan meets MIL-STD-105E. A coordinate measuring machine (CMM) is used for in-process and final mechanical inspections of vacuum chambers and other complex or close tolerance parts. CMM printouts of chamber final inspections can be furnished upon request. Nor-Cal Products is ASME U Stamp Certified. Stamped components are fabricated to the latest edition of the ASME BPV Codes. The ASME BPVC Certification Program conforms to the rules governing the design, fabrication, materials, assembly, and inspection of boiler and pressure vessel components during construction. ASME certification is recognized in the United States, Canada, and an estimated 100 countries worldwide.
Building quality into our components is our most important task.
