Production Requirements For SMT Patch Processing

The production requirements of SMT chip processing are relatively high, because in PCBA processing, whether it is patch processing or other processing technology, it is a relatively precise type of processing, and there can be no errors and poor processing. Since there are many processing procedures involved, many requirements need to be carried out throughout the processing and production process. For example, it is necessary to quota management of solder paste, repair glue and component losses, and control factors such as process parameters, process, personnel, equipment, materials, process testing and shop environment.

The high quality requirements of SMT chip processing require us to apply a clear work responsibility system, such as SMT chip processing related positions operators need to conduct professional training, and implement the first piece inspection.

1. the production site setting is reasonable, the mark is correct; Warehouse materials and products in process shall be sorted and stacked neatly in accordance with the ledger. 

2. Product batch management: The nonconforming product control procedures shall clearly specify the isolation, identification, recording, review and treatment of nonconforming products. Generally, rework should not exceed three times, and component rework should not exceed two times.

3. Civilized production: clean, no debris, civilized operation, no barbaric and disorderly operation. Site management must have system, inspection, evaluation and record, and carry out "6S" (classification, rectification, cleaning, cleaning, literacy, service) activities every day.

The maintenance and maintenance of SMT processing equipment: key equipment should be regularly checked by full-time maintenance personnel, so that the equipment is always in good condition, tracking and monitoring the status of the equipment, timely detection of problems, take corrective and preventive measures, timely maintenance and repair.
