Quality Inspection Process
Quality Inspection Process
1. Pre-Production Quality Control
1.1 Supplier Qualification
• Supplier Audit:
◦ Conduct on-site audits to evaluate production facilities, labor conditions, and environmental compliance.
◦ Verify certifications (e.g., ISO 9001, ISO 14001, ISO 45001, RBA).
• Material Traceability:
◦ Require suppliers to provide full documentation for raw materials (e.g., conflict-free minerals, RoHS/REACH compliance).
1.2 Design & Prototype Validation
• Design Review:
◦ Collaborate with engineers to validate product specifications, safety standards, and regulatory requirements.
• Prototype Testing:
◦ Test prototypes for functionality, durability, and compliance with target market regulations (e.g., CE, FCC, UL, KC).
2. In-Production Quality Control
2.1 Incoming Material Inspection
• Sampling Plan:
◦ Use AQL (Acceptance Quality Limit) Level II (ANSI/ASQ Z1.4) for batch sampling.
◦ Test critical components (e.g., lithium batteries, PCBs) for safety and performance.
• Documentation:
◦ Verify material certificates (e.g., MSDS, COC) and batch numbers.
2.2 Production Line Monitoring
• Process Control:
◦ Implement Statistical Process Control (SPC) to track critical parameters (e.g., soldering temperature, torque settings).
◦ Conduct daily checks on 10% of units for defects (e.g., short circuits, cosmetic flaws).
• Real-Time Reporting:
◦ Use IoT sensors and QC software (e.g., QIMAone, InspectionXpert) to log defects and trigger alerts.
3. Pre-Shipment Inspection
3.1 Final Random Inspection
