Abstract

The invention provides a circuit board developing solution recycling system. The system comprises a developing solution tank, a discharge port of the developing solution tank is connected with a feeding port of a concentrated water tank through a pipeline, and a discharge hole of the concentrated water tank is sequentially connected with a membrane filtration device through a pipeline. A first discharge hole of the membrane filtering device is connected with a feeding hole of the developing solution tank through a pipeline, a second discharge port of the membrane filtration device is connectedwith the feeding port of the concentrated water tank through a pipeline, a plurality of valves are mounted between the pipelines and electrically connected with a PLC to realize the switching betweena forward filtration mode and a reverse filtration mode, and a cleaning system is further arranged between the concentrated water tank and the membrane filtration device. The circuit board developingsolution recycling system provided by the invention enables the developing solution to be recycled, and is high in filtering efficiency and low in emission.

Description

technical field [0001] The invention relates to a recovery system, in particular to a circuit board developing solution circulation recovery system. Background technique [0002] In the prior art, a method of draining all the developing solution in the developing solution pool or continuously replenishing new developing solution at certain intervals is often used to treat the developing solution. Drain all the developer together, have to stop the operation and need to adjust subtle development parameters when continuing to operate, which is not suitable for large-scale production needs. In the method of continuously replenishing a new developer at regular intervals, if the discharge amount is reduced, the developing ability will be extremely reduced, and the degree of contamination of the developer in the developer pool will become very high. The degree of contamination of the developer in the developer tank and the degree of contamination of the developer supplied for deve...
