Smartwatch Quality Control Process (English Version)

1. Incoming Quality Control (IQC)

• Inspect all incoming materials (components, casings, batteries, screens, etc.) for specifications and quality

• Perform sampling inspections according to the AQL standard

• Isolate, return, and record non-conforming items

2. In-Process Quality Control (IPQC)

• Set inspection points in key processes (SMT, assembly, testing)

• Check items such as soldering quality, assembly alignment, and functionality

• Perform patrol inspections every hour and document. Stop the line and analyze issues when defects occur

3. Final Quality Control (FQC)

• Inspect appearance (scratches, dirt, misalignment, etc.)

• Perform full functionality tests (touchscreen, display, connectivity, sensors, audio, calls, 4G, GPS, etc.)

• Test battery performance, signal strength, and thermal performance

• Reject non-conforming products before they reach the packaging process4. Outgoing Quality Control (OQC)

4. Outgoing Quality Control (OQC)

• Inspect packing integrity, labeling, serial number, and accessories per order

• Check the packing quantity and packaging firmness

• Perform a final inspection of some units’ functions before shipping

• Issue an outgoing inspection report

5. Customer Complaints & Continuous Improvement (CAPA)

• Collect after-sales feedback and customer complaints

• Conduct 8D meetings for major quality issues

• Implement corrective/preventive actions and update inspection standards or procedures

• Track improvements and close the loop
