In the process of printed circuit board production, there are two main types of electroplating equipment, one is horizontal electroplating line, the other is vertical electroplating line.These two different structures of electroplating equipment, mainly the circuit board transport mode is different, the transport plate equipment structure is not the same, so for maintenance is also slightly different.
Daily maintenance and maintenance methods
1, tank maintenance and maintenance of vertical electroplating line and horizontal electroplating line is the main difference between the PCB transport mode is different, but for the tank maintenance and maintenance methods are essentially the same.On 7d, each washing tank shall be cleaned once. The pickling tank shall be cleaned once and the tank fluid shall be replaced.Check the sprinkler device in the tank to see if there is any blockage. Dredge the blockage in time.The conductive support and anode on the copper and tin plating groove and the contact position between the anode and the wire can be cleaned and polished with a cloth and sandpaper.Check the titanium basket and tin bar basket of the copper bath and tin bath once, replace the rotten titanium bag and tin bar basket, add copper ball and tin bar, and electrolyze the copper bath and tin bath after adding copper ball and tin bar on 7d.
7d also use high and low current mode for trial production, so that the newly added copper ball, tin bar, after the completion of the production performance is stable before production.Clean the copper ball and anode bag once every 90.Activated carbon is used every 120~150d to filter and clean the tank liquid, remove impurities in the tank liquid, and clean the tin tank once.
2. Maintenance and maintenance of vibration mechanism of vertical electroplating line on vertical electroplating, in order to ensure the uniformity of surface copper and the effect of copper hole during electroplating, the plate will vibrate and sway, and the tank will have vibration and sway mechanism.
30d to check the reducer, see whether it is running normally, check its fastness;Check the fastness of vibration mounting motor bolts;Check the wear of vibration rubber, wear more serious, to be timely replacement.
180d check the contact of power lines in the junction box, tighten the loose joints in time, and replace the melted or aging power lines in time to ensure the insulation between the power lines.All bearings on the vibration mechanism should be checked once, grease should be lubricated once, and bearings with serious wear and tear should be replaced in time.
3, the maintenance and maintenance of the vertical electroplating line is the use of the vertical electroplating line, hanging tools to the circuit board transmission.Clean the crane and hanger once a week (do not disassemble the crane and hanger) to keep its appearance clean and tidy. Use a cloth to wipe and polish the crane and hanger with sandpaper when cleaning.30d check the hanger once to check the damage of the hanger;Check and maintain the motor and reducer of the train, check the whole transmission device, and ensure its normal operation.180d carry out an in-depth cleaning and maintenance of the running gear and suspension gear. Remove the suspension gear from the running gear and clean it.
4, horizontal electroplating line conveyor maintenance and maintenance of horizontal electroplating line using the conveyor is a roller, the use of the rotation of the roller will continue to the circuit board into each slot, therefore, the maintenance of horizontal electroplating line conveyor and vertical electroplating line has some differences.7d clean the rollers of horizontal electroplating line once, clean the foreign matters adhered on the rollers, so as to ensure the clean surface of the transport plate;Check the actuator for looseness.Check the roller once every 180d to check whether the roller is worn, and timely replace the worn roller to ensure that the phenomenon of stuck plate will not occur in the conveyor plate;To the transmission gear, transmission shaft and the entire transmission system device for a check, timely repair problems.
5. Maintenance and maintenance of the circulatory filtration system 7d check the filter cylinder of the circulatory filtration system to see whether there is leakage in the filter cylinder.Clean or replace the filter cotton core every 10~15d.Replace the filter carbon core at 30d to ensure the quality of the filter and the flow rate of the filter;To clean the filter pump and clean the air pump filter hood and filter net.30d check the contact situation of the power cord connector of the pump motor once, tighten the loose cable in time, replace the old cable with a new one, so as to ensure good contact and safe insulation and protect the motor.
6. Other parts of the maintenance and maintenance 7d to the power supply output power should be checked twice;Power supply, electrical control of the popular heat dissipation, radiator inspection, dust removal, cleaning, to prevent its impact on heat dissipation.Check the electrical components of the electrical unit at 30d, and replace them in time if there is any damage or corrosion;Check all connectors, such as poor contact, virtual connection and virtual welding phenomenon should be repaired in time, such as rust and damage should be replaced in time;Check all contactors and relays, if there is bad contact or contact adhesion, timely replacement;Check the main parameters of capacitors, reactors and resistors, and replace them as soon as possible.
Check and calibrate the automatic feeding system once every 7d.Clean up the scale and dirt on the electric heater on 7d to prevent the internal temperature of the electric heater from being too high.
For each water and air pipe system, check it once every 7 days to see whether there is any phenomenon of running or leakage of gas and liquid, and timely repair and replace the pipelines with the phenomenon of running or leakage of gas and liquid.
By the discussion, the maintenance of long-term outage before long downtime if equipment plan, to carries on the maintenance, in the process of stop not erosion during aging, to do: clean up the ground, wipe up the water on the ground, and keep the ground dry, and make the test machine, slot, driving, hanging fixture should be kept clean and dry;All motors are best protected with fresh paper;All bearings are injected with grease to prevent rust;All potions in the pipeline should be cleaned;Clean the liquid medicine in the filter barrel of the filter;Remove the filter element from the filter and clean it.All heaters in the tank should be cleaned to remove dirt and keep dry.
Printed circuit board production application of electroplating equipment, as a result of the production process is different, the manufacturer is different, the device will have certain difference, therefore, will have some differences in maintenance methods, but must be to promptly correct maintenance of equipment, must not ignore due to cast out production schedule, production of equipment maintenance and maintenance, only do maintenance correct, timely, to guarantee the functioning of the equipment, stable performance and ensure the production and quality of production.
