What are the countermeasures for common failures of PCB plating lines?
PCB board factory: what are the common fault countermeasures for PCB electroplating line? Let's take a look at the following:
1. The copper strip of the auxiliary anode must be the same length as the production board and arranged close to the board.
2, the auxiliary copper strip has become thick and it is not allowed to be used again.
3, the whole board and the pattern after plating need to make the next process within 24 hours.
4. Wear spun gloves on the graphics-plated board, brown rubber gloves on the lower board, rubber gloves on the whole board, and dry roving gloves on the lower board.
5. When adding nitric acid and sulfuric acid, you must wear a protective helmet, protective leather skirt and rubber gloves.
6. When adding all materials, you need to add it when there is no plate in the tank; when adding copper sulfate, stannous sulfate, and sodium persulfate solids, you need to dissolve it with water first, and then add the water to the central control tank or add it when there is no plate in the tank Into the plating tank.
7. When the normal production is not possible due to a traffic failure, the board should be called out in the following order: micro-etching - degreasing - copper plating - tin plating - pickling acid. All boards are taken out of the rack after washing in the corresponding washing tank, and the tank number and plating time are marked.
8. If the production stop time is more than 2 hours, 15ASF is required to tow the cylinder for 1 hour; if the production stop time is more than 8 hours, it is required to use 10ASF and 20ASF to tow the cylinder for 1 hour.
The above is the relevant content of the common fault countermeasures of PCB electroplating line, I hope it will be helpful to you.
