In the Pcb manufacturing production , the solder paste, patch adhesive, and component loss should be managed in a fixed amount and as one of the key process control contents. Pcb manufacturing productiion directly affects the quality of the product, so it is necessary to control the technics parameters, processes, personnel, equipment, materials, processing inspection, workshop environment and other factors.
Key positions should have a clear job responsibility system. Pcb operators should be strictly trained and certified to work. Pcb manufacturers should have a formal production management method, such as the implementation of the first-piece inspection, self-inspection, mutual inspection and inspection system of inspectors. If the previous inspection fails, it cannot be transferred to the next process.
1.Product batch management. The unqualified product control procedures shall clearly be defined the isolation, identification, recording, review and handling Usually the SMA should not be repaired more than three times, and the repair of the components should not exceed two times.
2.Maintenance of Pcb manufacturing equipment. The key equipment should be checked by the full-time maintenance personnel, so that the equipment is always in good condition, the equipment status is tracked and monitored, problems are discovered in time, corrective and preventive measures are taken, and maintenance and repair are carried out in time.
A.Water and electricity supply.
B.pcba production line environment requirements —- temperature, humidity, noise, cleanliness.
C.Pcba site (including component library) anti-static system.
D.Access system, equipment operation rules and technics discipline of pcba production line.
4.The production site is set to be reasonable, the logo is correct; the warehouse materials, in-process product storage by category, neatly arranged, the account is consistent with actual material.
5.Civilized production. Including: clean, no debris; civilized operation, no barbaric disorder behavior. On-site management must have system, inspection, assessment, and records, and conduct daily “6S” (Sort, rectify, sweep, clean, accomplishment, service) activities.

① Standard components should pay attention to the dimensional tolerances of components from different manufacturers. Non-standard components must be designed in accordance with the actual size of the components and the land pattern and the space between the land. ② When designing high-reliability...
The water cleaning process of PCB circuit board uses water as the cleaning medium. A small amount (usually 2% to 10%) of surfactants, corrosion inhibitors and other chemicals can be added to the water. The PCBA cleaning process is completed by washing, washing and drying the source of pure water ...
