Description

Technical Field

[0001] The utility model belongs to the technical direction of PCB board etching, and specifically relates to a filter material tray for PCB board etching. Background Art

[0002] PCB board etching is an important step in making circuit boards. The principle is to etch away the copper layer through chemical reactions to form circuit patterns. The etching process is the most important and polluting link in the production process of circuit boards. After a period of use, the etching solution will produce some impurities such as oil and suspended matter that reduce the service life of the etching solution, which will affect the activity of the etching solution. When the impurities in the etching solution reach a certain level, the etching solution will not meet the etching indicators and cannot continue to be used.

[0003] 1. In the prior art, most filter trays for PCB etching cannot absorb the oil and suspended impurities in the etching solution, so that the oil and suspended impurities re-enter the etching solution, which greatly affects the service life of the etching solution.

[0004] 2. In the prior art, the filter plates in most filter trays for etching PCB boards are not easy to install and disassemble, making it inconvenient for workers to replace or repair the filter plates. Utility Model Content

[0008] By adopting the above technical solution, the setting and use of the filter plate in the solution can enable the filter plate to filter out pollutants such as organic matter, acid and alkali in the etching solution, thereby improving the quality of the etching solution and facilitating the reuse of the etching solution.

[0009] The utility model further illustrates that the outer wall of the main body is coated with anti-corrosion paint.

[0010] By adopting the above technical solution, the provision and use of the anti-corrosion paint in the solution can reduce the corrosion damage caused by the etching solution to the surface of the main body, thereby increasing the service life of the main body.

[0011] The utility model further illustrates that a mounting hole is opened on one side of the mounting frame, and the size of the mounting hole matches the size of the filter plate, and a second handle is installed on one side of the filter plate close to the mounting hole.

[0012] By adopting the above-mentioned technical scheme, the setting and use of the mounting hole and the second handle in the scheme can enable the staff to directly take out the filter plate from the inside of the mounting frame through the second handle, thereby facilitating the installation and disassembly of the filter plate, and then facilitating the staff to replace or repair the filter plate, thereby improving the convenience of the filter material tray.

[0013] The utility model further describes that threaded holes are provided on the front sides of the installation frame and the filter plate, and bolts are provided on the front side of the installation frame, and the bolts pass through the threaded holes to the inside of the filter plate, and the bolts form a threaded connection with the threaded holes.
