Pcb equipment daily maintenance and maintenance methods
Electroplating equipment occupies a large proportion in each PCB manufacturing enterprise, and in order to ensure the normal operation of electroplating equipment, to ensure the stability during operation and the service life of electroplating equipment, the correct maintenance and maintenance of equipment is very important, then, What is the most important thing in maintenance? 4-LAYER RIGID-FLEXIBLE BOARD.
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 differently, and the maintenance and maintenance methods for the tank are essentially the same.
7d should be cleaned once for each washing tank, clean it once and replace its bath; check the sprinkler in the tank to see if there is any blockage, and promptly clear the blockage. ;
For the copper plating tank, the conductive support on the tin plating tank and the contact position between the anode and the fire wire, when cleaning and cleaning once, wipe with a rag and sandpaper for grinding;
High Volume PCB Assembly.
Check the copper-plated tank, the tin-plated titanium basket, and the tin basket. Replace the rotten titanium basket and the tin basket. Add the copper ball and the tin bar. After adding the copper ball and the tin bar in 7d, Electrolysis is performed on the electroplated copper bath and the electroplating tin bath.
In 7d, high- and low-current methods are also used for trial production, so that after the newly added copper balls and tin bars are finished, the production performance is stabilized before production. The copper ball and anode bag should be cleaned once every 90.
The bath is cleaned and cleaned once every 120~150 days with activated carbon. The impurities in the bath are filtered out and the tin bath is cleaned once.

2. Maintenance and maintenance of the vertical plating line vibration mechanism In the vertical plating, in order to ensure the uniformity of the surface copper and the effect of the hole copper during the plating, the board will be vibrated and oscillated, and there will be a vibration swing mechanism on the tank body.
30d should check the reducer to see if it is working properly and check its tightness;
Check the tightness of the vibration-mounted motor bolts; check the wear of the vibrating rubber. For more serious wear, replace it in time.
180d Check the contact condition of the power cord in the junction box, and tighten the joint loosely. The power cord that melts or ages the insulation of the wire should be replaced in time to ensure the insulation between the power cables.
It is necessary to inspect all the bearings on the vibrating mechanism once, the last grease, and the bearings that are seriously worn out should be replaced in time.
