Maintenance and Repair of Printed circuit board plating production line

Home » Maintenance and Repair of Printed circuit board plating production line

Equipment types In the printed circuit board production process, the main use of electroplating equipment, there are two, one is the horizontal plating line, one is vertical plating line. These two different structure of the electroplating equipment, mainly the circuit board delivery in different ways, the use of the conveyor plate equipment structure is not the same, so the maintenance is also slightly different.

Routine maintenance and maintenance methods

1, the maintenance and maintenance of the tank The vertical plating line and the horizontal plating line is the main difference between the way the circuit board delivery, and for the tank maintenance and maintenance methods are essentially the same. 7d to the washing tank for a cleaning of the pickling tank, a cleaning and replace the bath; the tank of the spray device to conduct a check to see if there is any obstruction, the emergence of congestion to be timely to clear the situation ; On the copper plating, tin plating on the conductive bearing and the anode and the fire line contact position, a clean and clean can be wiped with a rag and sandpaper to polish; copper bath, tin bath tin basket, tin basket A check, replace the rotten titanium basket, tin baskets, and add copper balls, tin, in 7d to add the copper ball, tin, the need to electroplating copper tank, electroplating tin tank electrolysis.

7d also use high and low current way to test production, so that the new addition of copper balls, tin finished, the production of stable performance and then production. Every 90 to the copper ball and anode bag for a cleaning. Every 120 ~ 150d using activated carbon on the bath for a filter cleaning, filter out the impurities in the bath, tin bath for a cleaning.

                        

2, the vertical plating line vibration maintenance and maintenance of vertical plating, in order to ensure the copper plating when the uniformity of copper and the effect of copper, the board will be vibration swing, the tank will have vibration swing mechanism.

30d to check the reducer to see if it is working properly, check the tightness; to check the vibration of the motor bolts to install the tightness; check the vibration of the rubber wear, for more serious wear and tear, to be timely replacement.

180d on the junction box within the power cord to check the situation, the emergence of loose joints to be tightened in time, the insulation of the wire insulation or aging of the power cord, to replace the power cord in time to ensure the insulation between the power cord; To check all the bearings on the vibration mechanism, the last grease, the wear and tear of the bearings to be timely replacement.

3, vertical plating line maintenance and maintenance of vertical plating line is the use of traffic, linked to the circuit board for transmission. Every week to clean the crane and staircase (driving and hanging with no demolition), so that the appearance of clean and tidy, cleaning can be wiped with a cloth, and use sandpaper polished. 30d on the staircase to conduct a check to see the hanging of the damage; the motor and gear reducer to check and maintain a check its entire transmission to ensure its normal operation. 180d on the driving and hanging with a thorough cleaning and maintenance, to be linked from the car to remove the cleaning down.

4, the level of plating line conveyor maintenance and maintenance level of the plating line used in the conveyor device is a roller, the use of roller rotation of the circuit board into the continuous tank, so the horizontal plating line conveyor maintenance and vertical plating line Some different. 7d on the level of the plating line of a roller cleaning, cleaning the wheel attached to the foreign body to ensure that the board when the conveyor plate clean; to check the interlock to check whether there is loose. Every 180d on the roller to conduct a check to check whether the wheel wear and tear, the emergence of wear and tear of the wheel in a timely manner to ensure that the conveyor plate will not appear when the phenomenon of card board; to the transmission gear, drive shaft and the entire drive system Carry out a check, for the timely problems of repair.

5, the maintenance and maintenance of the circulating filter system 7d on the filter system filter filter to check once, check the filter cartridge is leaking. Every 10 ~ 15d time, to filter cotton core for a clean or replacement. 30d to replace the filter core to ensure the quality of the filter and the filter flow; to filter the pump to clean and clean the filter air filter and filter. 30d Check the pump motor power cord connector contact situation, found loose to be tightened in time, the wire aging to replace the new wire to ensure good contact and safety insulation, to protect the motor.

6, other parts of the maintenance and maintenance 7d to the power of the output power of the two checks; to power, electrical control of the popular cooling, radiator to check, dust, clean, to prevent its impact of heat. 30d on the electrical unit of electrical devices to check, if damaged and corrosion should be replaced; check all connectors, if bad contact, such as false and virtual welding and other phenomena to be timely repair, if the corrosion and damage to be replaced; Check the contactor and relays, if the contact bad contact or contact adhesion, to be replaced; check capacitors, reactors and resistors and other components of the main parameters, if abnormal, as soon as possible to replace.

For automatic feeding system, 7d check the calibration once. 7d to clean up the scale and dirt on the electric heater to prevent the internal temperature of the electric heater is too high.

For the water, gas pipeline system, 7d to conduct a check to see whether there is running, leakage of liquid phenomenon, for the emergence of running, leakage of liquid pipeline to the timely maintenance and replacement.

Second, long-term maintenance before the maintenance of discussion If the equipment plan for a long time downtime, to its conservation, so that it will not be in the process of downtime erosion, to do: clean the ground, clean the ground water, so that the ground Keep the dry, and the machine, the tank, driving, hanging with a clean, dry; all the best use of fresh paper bag to protect the package; all bearings injection of grease, for rust; All the cleaners in the tank should be cleaned, except for the dirt, keep dry. The filter is clean and clean.

Printed circuit board production and application of electroplating equipment, due to the production process is different from the manufacturers used in the equipment will be a certain difference, therefore, there will be some differences in maintenance methods, but must be timely and correct equipment Maintenance, must not catch the production schedule, production and neglect of the equipment maintenance and maintenance, only to maintain the correct and timely, in order to ensure the normal operation of equipment, stable performance, to ensure the production of production and quality.
