Description

Technical Field

[0001] This utility model relates to the field of PCB processing technology, specifically to an effective device for preventing chemical residue from being carried over. Background Technology

[0002] In the PCB manufacturing industry, chemical back-carrying devices are used to reduce the amount of chemicals carried out of PCBs after chemical treatment. These include water-absorbing module-type chemical back-carrying devices, which can specifically absorb chemicals from both sides of the PCB, effectively reducing the amount of chemicals carried out, lowering chemical maintenance costs and water consumption, and reducing environmental pollution.

[0003] The existing liquid absorption device still has the following problems when in use: the water absorption components of its absorption mechanism wear out quickly. That is, the water absorption components in the absorption module, such as sponges, are easily subjected to friction and corrosion from the liquid during long-term contact with the PCB board to absorb the liquid, resulting in rapid wear. Disassembly and replacement are inconvenient, increasing maintenance costs and downtime. In addition, the absorption effect is affected by the flatness of the PCB board surface. If the PCB board surface is uneven or bumpy, the water absorption components of the absorption mechanism may not be able to fully adhere to the board surface, resulting in some areas of liquid not being effectively absorbed, thus affecting the absorption effect.
