Maintenance of printed circuit board electroplating production line

In the production process of printed circuit boards, there are two kinds of electroplating equipment, one is horizontal plating line and the other is vertical electroplating line. The two different structure of the electroplating equipment, mainly the circuit board transportation mode is different, the adopted transport plate equipment structure is not the same, so for maintenance is also slightly different.


First, routine maintenance and maintenance methods


1, groove maintenance and maintenance, vertical plating line and horizontal plating line of the main difference is that the circuit board delivery mode is different, and for the tank maintenance and maintenance method is essentially different. To the washing tank for a cleaning of pickling tank, a cleaning and replacement of the tank; the tank body spray device to conduct an inspection and check if there is congestion, the congestion situation should be timely to dredge; copper bath, tin groove on the conductive support and anode and the contact position on a clean, clean dishcloth and available sandpaper grinding; groove, groove of copper tin tin, titanium basket basket for a check, replace the rotten titanium basket bags, tin basket, and add copper ball, tin, copper, tin ball end in addition. Must, electrolysis copper plating bath, plating bath.


2, vertical plating line vibration mechanism maintenance and maintenance in vertical plating, in order to ensure the copper surface uniformity and copper hole effect, will plate vibration vibration, the tank will have vibration vibration mechanism.


Check the reducer, to see whether the normal operation, check the tightness; to check the fastening bolt installation of motor vibration; check the wear of rubber vibration, the wear is more serious, the need for timely replacement.


Maintenance of vertical plating line, 3 vertical plating line driving is the use of traffic, transport rack of circuit board. To conduct a cleaning of the crane and a hanger (weekly traffic and without removing the rack), make its appearance neat, clean cloth can be used when wiping, and use sandpaper. A check on the rack, the rack view breakage; conduct an inspection and maintenance of the motor and the speed reducer driving, view the entire drive device, to ensure their normal operation. For a thorough cleaning and maintenance of vehicles and hangers, should be removed from the rack on the clean vehicle.


4, the level of transmission device maintenance plating line conveying device and the maintenance level of the plating line is used by the rotation of the roller wheel, will be sent to each tank circuit board continuity, therefore, transmission level electroplating line maintenance for some different and vertical plating line. A cleaning of the horizontal plating line is carried out to clean the foreign matter adhered on the roller so as to ensure that the board surface is clean during the conveying plate; the interlocking device shall be checked to check whether it is loose or not. Carry out a check on the wheel, check wheel wear, timely replacement of wear of roller, to ensure that the card phenomenon does not occur in the transportation board; to carry out an inspection of the transmission gear, the transmission shaft and the transmission system, for the issue of timely repair.


Second, long before shutdown maintenance plan long time discussion if the equipment downtime, to the maintenance, so that it does not stop when the erosion of aging, should clean the ground, clean the water on the ground, so as to keep the ground dry, and make the machine, groove, driving, hanging to keep clean and dry; all motor is best to use plastic wrap protection; all bearing grease injection, to rust in the pipeline; all drops all put clean; filter bucket drops put clean; remove the filter filter clean; all heater tank must be clean, remove dirt keep dry.


Electroplating equipment application for printed circuit board production, due to the different production process, used in the equipment of different manufacturers, there will be some differences, therefore, in the maintenance method, there will be some differences, but must be correct and timely maintenance of equipment, must not be due to catch the production schedule, production and ignore the maintenance of equipment and maintenance, maintenance only correctly and timely, in order to ensure the normal operation of the equipment, stable performance, guarantee the quantity and quality of production.
