Description

Technical Field

[0001] The utility model belongs to the technical field of printing, in particular to a membrane residue filtering device for a printed circuit board. Background Art

[0002] Printed circuit boards often use a wet process, which uses a large amount of chemical liquid to react with the surface of the circuit substrate to complete the production of the circuit board; the waste liquid after the reaction can be recycled if treated to reduce pollution to the environment and waste of raw materials.

[0003] According to a printed circuit board film residue filtering device disclosed (publication number: CN219517929U), it includes a shell, a top cover, an observation window, a first receiving plate, a first filter screen and a guide ring. The top of the shell is provided with a top cover, an observation window is installed in the middle of the top cover, a first receiving plate is provided in the middle and upper part of the shell, a guide ring is embedded in the middle and upper part of the inner side of the shell, and a first filter screen is movably connected in the middle of the guide ring, and the first filter screen is in close contact with the first receiving plate. Pour the film residue waste liquid to be filtered into the shell, pass through the guide ring, and come to the first filter screen. The first filter screen filters out large particles in the waste liquid. When the waste residue in the first filter screen is stored to a certain amount, the first receiving plate and the first filter screen are pulled out. After collecting the waste residue, the first filter screen is cleaned and put back to its original place. However, in the above device, the first receiving plate, the first filter screen and the guide ring cooperate with each other, so it is difficult to achieve the effect of filtering the circuit board film residue, which reduces the manufacturing quality of the circuit board and increases the production of defective products, which needs to be improved.
