There are two main types of electroplating equipment used in the production of printed circuit boards. One is a horizontal electroplating line and the other is a vertical electroplating line. These two different structures of electroplating equipment are mainly different in the transportation method of circuit boards. The structure of the conveying plate equipment used is also different, so the maintenance is slightly different.
Daily maintenance and maintenance methods
1. Maintenance and maintenance of the tank The main difference between the vertical plating line and the horizontal plating line is that the circuit board is transported in different ways, and the maintenance and maintenance methods of the tank are essentially the same. 7d. Wash each water tank once. Pickle tank, clean once and change its tank fluid. Check the spray device inside the tank to see if there are any blockages. Unblock them if necessary. ; For the copper-plated tank, tin-plated tank, the conductive support and the anode and the live wire contact position, you can use a rag to wipe and sandpaper for a single cleaning; for the copper-plated tank, tin-plated tank, titanium basket, tin strip basket Check once, replace the rotten titanium basket bag and tin bar basket, and add copper balls and tin bars. After adding the copper balls and tin bars at 7d, the electroplated copper bath and electroplated tin bath must be electrolyzed.
7d also uses the high and low current methods for trial production, so that after the new copper balls and tin bars are added, the production performance is stable before production. Clean the copper balls and anode bags every 90 minutes. Every 120 to 150 days, the bath is filtered and cleaned with activated carbon, the impurities in the bath are filtered, and the tin bath is cleaned once.
2. Maintenance and maintenance of the vibration mechanism of the vertical electroplating line On the vertical electroplating, in order to ensure the uniformity of the surface copper and the effect of the hole copper during electroplating, the plate will be vibrated and oscillated, and the tank will have a vibration oscillating mechanism.
30d should check the reducer to see if it runs normally and check its tightness; check the tightness of the vibration mounting motor bolts; check the wear of the vibration rubber, and replace it in a timely manner if the wear is more serious.
180d Check the contact condition of the power cords in the junction box, and tighten them in time when the joints are loose, and replace the power cords in a timely manner to ensure the insulation between the power cords. All the bearings on the vibration mechanism should be inspected once, the last time grease, and the heavily worn bearings should be replaced in a timely manner.
3. Maintenance and maintenance of vertical electroplating line driving The vertical electroplating line transfers circuit boards by using traveling and hanging gears. Clean the crane and the hanger once a week (the driving and the hanger do not need to be disassembled) to keep its appearance neat. When cleaning, you can use a rag to wipe and sand it with sandpaper. 30d Check the hanger once to check the damage of the hanger; check and maintain the motor and reducer of the vehicle, and check its entire transmission to ensure its normal operation. 180d Carry out an in-depth cleaning and maintenance of the vehicle and the hanger, and remove the hanger from the vehicle for cleaning.
4. Maintenance and maintenance of the horizontal electroplating line conveying device The roller used in the horizontal electroplating line is a roller. The rotation of the roller is used to continuously feed the circuit board into each slot. Therefore, the maintenance of the horizontal electroplating line conveying device and the vertical electroplating line are: Something different. 7d. Clean the rollers of the horizontal plating line once, and clean the foreign matter adhered to the rollers to ensure that the board surface is clean when conveying the board; check the coupling to see if it is loose. Check the rollers every 180d to check whether the rollers are worn, and replace the worn rollers in a timely manner to ensure that no jamming occurs when conveying the plates; the transmission gears, shafts and the entire transmission system Perform an inspection to repair any problems that occur.
5. Maintenance and maintenance of the circulating filter system 7d Check the filter cartridge of the circulating filter system once to see if there is any leakage in the filter cartridge. Every 10 to 15 days, the filter cotton core should be cleaned or replaced. At 30d, the filter carbon core should be replaced to ensure the quality of the filter and the flow of the filter; the filter pump should be cleaned once and the filter air hood and filter of the air pump should be cleaned. 30d Check the contact of the pump motor power cable connector once. If it is found loose, tighten it in time. If the wire is aging, replace it with new wire to ensure good contact and safe insulation to protect the motor.
6. Maintenance and repair of other parts 7d. Check the output power of the power supply twice; check the power supply, electrical control of the heat dissipation, and the radiator, and remove dust and clean to prevent it from affecting the heat dissipation. Check the electrical components of the electrical unit at 30d, and replace them if they are damaged and corroded; check all connectors, and repair them in time if they have poor contact, false connections, and soldering; Check each contactor and relay. If the contact is bad or the contact is stuck, replace it in time. Check the main parameters of capacitors, reactors and resistors. If abnormal, replace it as soon as possible.
For automatic feeding system, check and calibrate once in 7d. 7d. Clean the scale and dirt on the electric heater to prevent the internal temperature of the electric heater from becoming too high.
For each water and gas pipeline system, check it once in 7d to see if there is any phenomenon of running, leaking liquid, etc., and timely repair and replace the pipeline with the phenomenon of running, leaking liquid.
Second, 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 do: clean the ground, wipe the water on the ground, and make the ground Keep it dry and keep it clean and dry on the machine, in the tank, on the vehicle, and on the hangers. All motors are best wrapped with plastic wrap. All bearings are injected with grease to prevent rust. All the medicines are cleared; the medicines in the filter barrel of the filter are cleared; the filter element of the filter is taken out and cleaned; all heaters in the tank must be cleaned to remove dirt and keep dry.
For electroplating equipment used in printed circuit board production, due to different production processes and different manufacturers, there will be certain differences in equipment, so there will be some differences in maintenance methods, but the equipment must be timely and correctly Maintenance, we must not ignore the maintenance and maintenance of the equipment because of the production progress and output. Only by maintaining the maintenance correctly and timely, can we ensure the normal operation of the equipment, stable performance, and ensure the production yield and quality.
