11. Organize the OEM factory to hold a production preparation meeting, list the production precautions, the person in charge of each section and the production plan, etc.

12. Participate in each link of factory production, record the problem points of each link, and carry out on-site problem-solving, troubleshooting, and preliminary statistics of working hours.

13. At the end of production, conduct a trial production summary, collect factory data and count bad records, and make production reports.

14. Track the maintenance status of defective products, count maintenance results, list defective points that may occur in mass production, and make defective product maintenance reports.

15. Participate in the Review Meeting trial production summary meeting, list the production problems and the responsible departments of the problem points, as well as solutions and measures.

16. According to the problem points of the product, raise questions to the responsible department and track and record the process of solving the problem by the responsible department.

17. According to the results of production, modify and perfect the fixture.

18. Modify and optimize WI (working instruction) according to the results of production

19. Summarize the complete product production report.

20. Ongoing problem tracking.

NPI (New Product Introduction) PVT Workflow

1. Participate in Kick-off Meeting to comprehensively check whether there are unresolved problems and newly added processes in product production.

2. Hold a production preparation meeting to confirm the work preparation of each department, and at the same time propose a list of materials and checklists required for production to each department

3. Notify the quality department to issue quality inspection standards to the factory, including incoming material inspection standards, PCBA inspection standards, finished product inspection standards, etc.

4. Issue the official WI (working instruction) of each section to the factory, including SMT patch, THT plug-in, assembly, testing, packaging, etc.

5. Issue software to the factory

6. Issue production materials to the factory, including BOM, Gerber Files, hardware layout files, process documents, packaging information, etc.

7. Communicate material status and production plan with PMC to prepare for production.

8. Make mass production notices, which contain product details and key contacts.

9. Hold a production preparation meeting with the OEM factory to arrange the production plan of each section and the corresponding person in charge.

10. Track incoming materials inspection to prevent quality problems in incoming materials from affecting production.

11. Carry out production according to the production process flow specified by Flow Chart, and deal with the problems in production in time.

12. Pay attention to the quality of the production process in the production process, prevent the occurrence of substandard production methods, and assist the QC engineer to supervise and prepare the on-site quality inspection report.

13. Collect various production data, including process data, quality data, and product data.

14. Calculate the production capacity of the product according to the working hours of each production step according to the output data.

15. Analyze the reasons for the failures in production, assign them to the responsible department, and follow up on the solutions and results.

16. Pay attention to product inspection results to avoid missing points.

17. Hold a product review meeting to summarize all problems in production and submit them to relevant departments.

18. Pay attention to the feedback of products shipped to customers, and make corresponding countermeasures according to the feedback.

19. Track design problems until a thorough solution and results are obtained.
