In the printed circuit board production process, the main use of electroplating equipment have two kinds, one is horizontal electroplating line, one is vertical electroplating line. These two different structures of electroplating equipment, mainly the circuit board transport way is different, the conveyor plate equipment structure is not the same, so for maintenance is also slightly different.
Daily maintenance and maintenance methods
- Tank maintenance and maintenance of vertical electroplating line and horizontal electroplating line is the main difference between the transport of the circuit board is different, and for the tank maintenance and maintenance method is not very different in nature. 7d to each wash tank for a cleaning of pickling tank, a cleaning and replacement of the tank liquid; The spray device in the tank body is checked to see if there is any blockage, and the blockage should be dredged in time; For copper plating tank, tin plating tank on the conductive support and anode and wire contact, cleaning cleaning can be used to wipe cloth and sandpaper polishing; Check the titanium basket and tin basket of copper plating tank, tin plating tank, replace the rotten titanium basket bag and tin basket, and add copper ball and tin bar. After adding copper ball and tin bar in 7 days, electrolysis of copper plating tank and tin plating tank shall be carried out.
7D also needs to use high and low current mode for trial production, so that after the addition of copper balls and tin strips, the production performance will be stable before production. The copper ball and anode bag should be cleaned every 90. Activated carbon is used to filter and clean the tank liquid once every 120~150d, to filter the impurities in the tank liquid, and to clean the tin tank once. - Maintenance and maintenance of vibration mechanism of vertical electroplating line In vertical electroplating, in order to ensure the uniformity of surface copper and the effect of hole copper when electroplating, it will vibrate and sway the plate, and there will be vibration and sway mechanism on the tank.
30d to check the reducer, to see whether it is running normally, check its fastening; Check the tightness of vibration mounting motor bolts; Check vibration rubber wear, wear more serious, to be replaced in time. - Vertical electroplating line maintenance and maintenance of the vertical electroplating line is the transmission of the circuit board by driving, hanging tools. The crane and hanger should be cleaned once a week (the crane and hanger need not be disassembled), so that the appearance of the crane should be kept clean. When cleaning, the crane and hanger can be wiped with cloth and polished with sandpaper. 30d to carry out an inspection of the hanging fixture, check the damage of the hanging fixture; Check and maintain the motor and reducer, check the whole transmission device to ensure its normal operation. 180D Carry out an in-depth cleaning and maintenance of the vehicle and the hanger. The hanger shall be removed from the vehicle for cleaning.
- Horizontal electroplating line transmission device maintenance and maintenance of horizontal electroplating line transmission device is a roller, the rotation of the roller will be continuous circuit board into each slot, therefore, the maintenance of horizontal electroplating line transmission device and vertical electroplating line have some differences. 7d the roller of the horizontal plating line is cleaned once, and the foreign matter adhered to the roller is cleaned to ensure that the surface of the plate is clean when conveying the plate; The coupling should be checked to see if it comes loose. Every 180d to check the roller, check whether the roller wear, wear of the roller timely replacement, in order to ensure that there will be no clamping phenomenon in the conveying plate; The transmission gear, drive shaft and the entire transmission system should be inspected, and problems should be repaired in time.
- The maintenance and maintenance of the circulation filter system 7d to check the filter cylinder of the circulation filter system, to see whether the filter cylinder leakage. Clean or replace the filter cotton core every 10 to 15 days. 30d to replace the filter carbon core, to ensure the quality of the filter and the flow of the filter; To clean the filter pump and clean the air filter hood and filter net of the air pump. 30d check the contact situation of the power cable joint of the pump motor once, and tighten it in time if it is loose. Replace the old wire with a new one to ensure good contact and safe insulation and protect the motor.
- Other parts of the maintenance and maintenance of 7d to the output power of the power supply twice check; To the power supply, electrical control of heat dissipation, heat sink inspection, dust removal, clean, prevent its impact on heat dissipation. 30d Check the electrical components of the electrical unit, and replace them in time if there is damage and corrosion; Check all connectors, if there is bad contact, virtual connection and virtual welding phenomenon should be repaired in time, if there is rust and damage to replace in time; Check each contactor and relay, if there is bad contact or contact adhesion, to be replaced in time; Check the main parameters of capacitors, reactors, resistors and other components, and replace them as soon as possible if abnormal.
For the automatic feeding system, check and calibrate once every 7 days. 7d to clean up the scale and dirt on the electric heater, prevent the internal temperature of the electric heater is too high.
For each water, gas pipe system, 7d to check it, to see whether there is running, leakage liquid phenomenon, for running, leakage liquid phenomenon of the pipeline to timely repair and replacement.
PCB electroplating production line
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 crisper wrap; All bearings are injected with grease to prevent rust; All the potions in the pipeline are clean; The liquid medicine in the filter bucket of the filter machine is put clean; Remove the filter element of the filter and clean it; All heaters in the tank should be cleaned to remove dirt and kept 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, In order to ensure the normal operation of equipment, stable performance, to ensure the production of output and quality.
