[0002] Electroplating solution (copper / nickel) is a critical and unique process in the manufacturing of printed circuit boards (PCBs / FPCs). It involves the use of a large number of chemicals (copper sulfate / nickel brightener, leveling agent, wetting agent, etc.). During the production process, organic byproducts are continuously produced, leading to an increase in TOC (total organic contamination), and the introduction of impurities and particles, including inorganic and metallic particles. This can reduce the yield of printed circuit boards and affect the quality of products in subsequent processes.

[0003] The conventional treatment methods for electroplating solutions currently on the market have long operation processes, high energy consumption, and require heating treatment during the carbon treatment process.

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0023] This application discloses a device for filtering and purifying electroplating solution. Figure 1 The feed device 1 is connected to the pressure filter device 2 through a pipeline, and the pressure filter device 2 is connected to the fine filter device 3 through a pipeline. Figure 2 As shown, the feeding device 1 includes a feeding solution tank 11 and a loader 12. The loader 12 is an electric feeding method. When running, the material enters the feeding solution tank 11 evenly and dissolves in the solution. The loader 12 is provided with a feeding opening and closing door 13, and the feeding opening and closing door 13 is equipped with an opening and closing lock 14.

[0024] like Figure 3 As shown, the pressurized filtration device 2 includes a filter press support 22 and an automatic filter press 21 arranged thereon, and a waste receiving structure is arranged below the automatic pulling plate structure of the automatic filter press 21, and the waste receiving structure includes a first waste receiving trough 23 and a second waste receiving trough 24 thereon, and an extension block is arranged on the side of the second waste receiving trough 24, and a pulley 25 that can slide on the first waste receiving trough 23 is arranged below the extension block; the automatic filter press 21 is hydraulically driven and has an automatic pulling plate function, and the internal filter plates can separate the solution from the carbon powder adsorbent; the filtered solution flows into the fine filter box 31, and the carbon powder adsorbent remains between the filter plate layers. After the filtration is completed, the automatic program is run to pull the filter plates apart, and the carbon powder adsorbent falls into the waste receiving structure. Under normal circumstances, it falls into the second waste receiving trough 24. When the second waste receiving trough 24 slides out for replacement, it will fall into the first waste receiving trough 23.

[0025] like Figure 4-6 As shown, the fine filtration device 3 includes a fine filtration solution box 31, which is equipped with a submersible water pump 32. The submersible water pump 32 is connected to a fine filtration barrel 33. The fine filtration barrel 33 includes four groups of filter elements. A water pump installation port 35 for installing the submersible water pump 32 is opened on the fine filtration solution box 31. The submersible water pump 32 is equipped with a water pump installation block 36. The water pump installation block 36 is installed at the water pump installation port 35 by bolts.

[0026] The fine filtration solution tank 31 stores the solution filtered by the automatic filter press 21. The submersible water pump 32 pressurizes the solution in the fine filtration solution tank 31 and sends it to the fine filtration barrel 33. There are four groups of precision filter elements in the fine filtration barrel 33 to filter the solution again. After passing through the fine filtration barrel 33, the solution flows back to the electroplating line.

[0027] The lower portion of the fine filtration solution tank 31 is stepped, and the submersible water pump 32 is inserted into the lowest step of the fine filtration solution tank 31 , thereby reducing the area that the submersible water pump 32 cannot pump.

[0028] The feed solution tank 11 and the fine filtration solution tank 31 are provided with perspective windows 34 for observing the liquid conditions inside.

[0029] In this embodiment, after the solution is processed, compressed air is passed through the automatic filter press 21 to dry the carbon powder inside the filter press. The automatic filter press 21 automatically pulls the plate to make the carbon powder fall into the waste trough below, and then the waste in the waste trough is manually recovered.

[0030] In this embodiment, the electroplating wire is connected to the device through a hose, and the solution is drawn from the electroplating wire for filtration treatment and then drawn back into the electroplating wire, thereby realizing continuous filtration and purification cycle production.

[0031] The implementation principle of this embodiment is:

[0032] The device is installed in the matching equipment for operation. The specific steps are as follows: the material (carbon powder) is manually poured into the feeder, and then the feeder evenly introduces the material into the electroplating solution tank to mix with the electroplating solution. The diaphragm pump presses the electroplating solution in the electroplating solution tank into the automatic filter press for filtration. The solution filtered by the automatic filter press enters the fine filter box, and the submersible water pump presses the solution in the fine filter solution tank into the fine filter barrel for fine filtration. The solution finally flows out of the fine filter barrel and is transferred back to the electroplating line through a hose for production.
