Key Operating Standards for SMT Equipment
- 1. SMT operators should possess a strong sense of responsibility and work carefully and diligently.
- 2. Operators must undergo systematic training from the engineering department before commencing duties, including education on process discipline and safety production.
- 3. Operators must pass an assessment and obtain qualification before being allowed to operate SMT equipment.
- 4. New operators should be supervised by a mentor during their initial period of operation.
- 5. Strictly adhere to the procedures outlined in the “Equipment Operation Manual,” with required process documents displayed before production begins.
- 6. It is forbidden to access or adjust menus that are not relevant to production; any adjustment during material shortages must involve engineering personnel.
- 7. Erection of material racks while the machine is running is strictly prohibited. Safety covers must be opened when installing a new rack, and the appropriate feeders must be used.
- 8. Never extend any body parts into the machine’s safety enclosure while it is operating.
- 9. Care should be taken to avoid rough handling; material racks should be orderly and securely positioned.
- 10. Operators must not leave the workshop for meals or end shifts while the SMT equipment is in operation.
- 11. Any error messages from the SMT equipment must be carefully reviewed. Operators should consult engineering personnel for any unclear messages.
- 12. Complete daily cleaning and maintenance tasks in accordance with the “Equipment Maintenance Manual,” and ensure they are documented and verified by engineering personnel.
- 13. Material changes in production must be documented, and confirmation by IPQC should occur within 15 minutes to ensure consistency.
- 14. The production display screen of SMT equipment should typically indicate a material throwing state, and any abnormalities must be reported immediately.
- 15. Only one type of material should be stored per production line; any leftover materials should be returned to the workstation with sufficient empty material tape reserved.
- 16. Strive to collect all necessary materials at the beginning of the shift to minimize interruptions for additional materials.
- 17. Prepare for material changes in advance to reduce downtime.
- 18. Empty material reels should be placed in the designated location for easy IPQC verification.
- 19. Maintain punctual production output records as prescribed.
- 20. Fill out downtime records accurately and in detail as per regulations.
- 21. At the end of the shift, complete detailed production information records and have them confirmed by the oncoming operator and engineering personnel.
- 22. Clean the area, dispose of used materials, and maintain the 5S principle before leaving.
- 23. Conduct an inventory check of important materials with the next operator when finishing the shift.
- 24. Fill out handover records according to prescribed guidelines when completing the shift.
- 25. Materials and tool records must be stored in designated areas; avoid clutter on the machines.
- 26. Waste tape should be cut promptly, with a specified length to prevent it from trailing into the waste basket while ensuring machine safety.
- 27. Complete any production boards still running before leaving for a meal or break.
- 28. Any abnormal equipment must be reported; if there is a red warning, engineering personnel must resolve the issue before reuse.
- 29. In the case of an equipment accident, the scene must be preserved without any excuses for tampering.
- 30. When shutting down SMT equipment, it must be done through normal procedures, returning to the origin point for the pick-and-place machine.
- 31. If manual placement is required due to equipment limitations, it must be confirmed by onsite engineering personnel, following the order of machine placement first before manual placement.
- 32. Before shift changes or production changes, the “three checks” must be performed: check for foreign objects inside the machine, ensure the rail width is suitable, and verify that the rail coupling platform is in a safe position.
- 33. During initial production, closely monitor material usage, flow, and substrate positioning within the machine.
- 34. Operators must wear anti-static gloves when handling ICs during production.
- 35. NG products with defects must be recorded according to IPC standards, and any boards with two or more defective units should be isolated for separate production.
