PCB plating production line maintenance(Part Ⅱ)
Equipment Types In the production process of printed circuit boards, there are two main types of plating equipment, one is horizontal plating line and the other is vertical plating line. These two different types of electroplating equipment, mainly the way the board is transported, the structure of the transport board used is different, so it is slightly different for maintenance.
Daily maintenance and maintenance methods
4. horizontal plating line conveyor maintenance and maintenance level The plating device used in the plating line is a roller, which uses the rotation of the roller to continuously feed the board into each slot. Therefore, the maintenance of the horizontal plating line conveyor and the vertical plating line have Some different. 7d Clean the roller of the horizontal plating line once and clean the foreign matter adhering to the roller to ensure the surface of the plate is clean when the plate is transported; check the connector to check for looseness. Every 180d, the roller is inspected once, the roller is inspected for wear, and the worn roller is replaced in time to ensure that the card does not appear when the plate is transported; the transmission gear, the drive shaft and the entire transmission system are required. Conduct an inspection and make timely repairs to the problems that arise.
5. Maintenance and maintenance of the circulating filtration system 7d Check the filter cartridge of the circulating filtration system once to see if the filter cartridge is leaking. The filter cotton core should be cleaned or replaced every 10~15d. In 30d, the filter carbon core should be replaced to ensure the filtration quality and the flow rate of the filter; the filter pump should be cleaned once and the filter hood and filter of the air pump should be cleaned. 30d Check the contact condition of the power supply connector of the pump motor and find that the looseness should be tightened in time. If the wire is aging, replace the new wire to ensure good contact and safe insulation and protect the motor.
6. Maintenance and maintenance of other parts 7d It is necessary to check the output power of the power supply twice; it is necessary to check the power supply, electrical control heat dissipation and radiator, dust removal and cleaning to prevent it from affecting heat dissipation. 30d Check the electrical components of the electrical unit. If there is any damage or corrosion, it should be replaced in time. Check all the connectors. If there is contact, virtual connection and virtual welding, it should be repaired in time. If there is corrosion and damage, it should be replaced in time; Check each contactor and relay. If there is contact failure or contact sticking, replace it in time; check the main parameters of capacitors, reactors and resistors. If abnormality occurs, replace it as soon as possible.
For the automatic feeding system, 7d should be checked and calibrated once. 7d should clean the scale and dirt on the electric heater to prevent the internal temperature of the electric heater from being too high.
For each water and gas pipeline system, 7d will be inspected once to see if there is any running or leaking liquid phenomenon, and the pipelines with running and leaking liquid phenomena should be repaired and replaced in time.
Maintenance discussion before long-term shutdown If the equipment is planned to be shut down for a long time, it should be maintained so that it will not be subject to erosion and aging during the shutdown process. To clean the ground, wipe the water on the ground, and make the ground Keep dry and keep the machine, tank, driving and hanging equipment clean and dry; all motors are best protected with plastic wrap; all bearings are injected with grease for rust prevention; The syrup is completely cleaned; the syrup in the filter filter tank is cleaned; the filter filter is removed and cleaned; all the heaters in the tank should be cleaned to remove dirt and keep dry.
Electroplating equipment for printed circuit board production applications, due to different manufacturing processes and different manufacturers, there will be some differences in equipment. Therefore, there will be some differences in maintenance methods, but the equipment must be timely and correct. Maintenance, must not neglect the maintenance and maintenance of the equipment due to the production schedule, production, only to ensure that the maintenance is correct and timely, to ensure the normal operation of the equipment, stable performance, to ensure the production and quality of production.
