Finished Quality Control (FQC) Management – Ensuring End-to-End Product Quality

In the final stage of manufacturing, Finished Quality Control (FQC) serves as the critical "last line of defense" to safeguard product quality before goods enter warehouse storage or reach customers. A well-structured FQC management system not only prevents non-conforming products from flowing into the market but also helps optimize production processes by addressing quality issues promptly. Below, we’ll break down the core processes, control measures, and key responsibilities of FQC to provide a clear roadmap for implementing effective end-product quality management.

Finished Quality Control (FQC) Process

1. Inspection personnel conduct incoming inspection for warehouse storage.

2. Qualified products are stored in the warehouse. For unqualified products, an Non-Conforming Report (NCR) shall be issued, and the Process Team shall host a Material Review Board (MRB) meeting.

3. Dispose of non-conforming products in accordance with the conclusions of the MRB meeting.

Finished Quality Control (FQC) Control Measures

FQC performs final inspection on products manufactured by each machine every 3 hours, following the standards of MIL-STD-105E II:

• For Category A and B products, and Category C products (with Inspection Level = I), the Acceptable Quality Level (AQL) is set as: Major Defects (MA) = 1.5 / Minor Defects (MI) = 2.5.

If the sampling inspection fails, an Non-Conforming Report shall be filled out and submitted to production and technical personnel. The production and technical personnel will then host an MRB meeting to address the issue, and record the handling results in the FQC Inspection Report.

Qualified products after FQC final inspection shall be promptly stamped with a blue "FQC + Serial Number" stamp before proceeding with warehouse storage operations.

Key Job Responsibilities and Precautions for Final Inspectors (FQC)

1.Conduct sampling inspection in accordance with inspection documents; generally, final inspection shall be performed every 3 hours as required.

2. When inspecting product dimensions, color difference, or conducting assembly tests, sampling inspection shall be carried out at a frequency of 2–3 molds per 3 hours.

3. During final inspection, it is mandatory to check whether the Product Qualification Certificate is filled out correctly—with special attention to product color and differentiation between "upper/lower" and "left/right" orientations of the product.

4. Sampling must be random. Any perfunctory behavior (e.g., cutting corners to avoid trouble) is strictly prohibited.

5. Upon discovering non-conforming products, mark them promptly (using a red non-conforming stamp), isolate them, and issue an Non-Conforming Report to the relevant responsible personnel for review and handling.

6. All non-conforming products that have undergone rework must be re-inspected in a timely manner. If the re-inspection still fails, a new Non-Conforming Report shall be issued.

7. Maintain proper handover and communication with Process Quality Control (PQC) personnel to prevent the occurrence of batch defective products.

8. When encountering tasks beyond one’s competence, promptly report to the QC Supervisor and follow their further disposal instructions.
