PCB Wet Processing Production Line: Essential Equipment And Functions

The PCB wet processing production line primarily involves a series of wet process equipment, which play a crucial role in the manufacturing of PCBs. The following are some common machines on the PCB wet processing production line and their functions:

1. Developing, Etching, and Stripping Equipment:

• Characteristics: This equipment usually features a one-piece etched spray disk design with precise nozzle positioning and uniform spray coverage. Additionally, it may have a chemical absorption function to reduce pooling effects and improve etching uniformity.

• Functions: Primarily used for the developing, etching, and stripping processes of PCB boards.

2. Brush Plating (Substrate Pretreatment) Equipment: Used for pretreating the substrate, such as cleaning and removing surface dirt, in preparation for subsequent processes.

3. Screen Printing Equipment:

• Functions: Using screen printing technology, it uniformly coats a wet film (photosensitive ink) onto the PCB board.

  
  

  

4. Drying Equipment:

• Functions: Dries the PCB board coated with wet film, causing the wet film to cure and form a stable adhesion layer.

5. Exposure Equipment:

• Functions: Uses ultraviolet light to expose the dried PCB board, transferring the pattern on the wet film to the PCB board.

  
  

  

6. Other Wet Process Equipment:

• Such as etching machines and stripping machines: These equipment play an important role in the manufacturing of PCBs, used for removing unwanted copper layers or wet film layers.

• Wastewater treatment equipment: Used for treating wastewater generated during production to ensure environmental compliance.

7. Auxiliary Equipment:

• Such as conveyors and worktables: These equipment are used to move PCB boards within the production line and provide operators with work platforms.

• Automated robotic arms: In some advanced PCB production lines, automated robotic arms are used for loading and unloading PCB boards, achieving automation of the production line.

It's worth noting that different PCB manufacturers and production lines may use different combinations of equipment and process flows. Therefore, in practical applications, the selection and configuration of corresponding equipment need to be based on specific requirements and production line configurations.

Additionally, as technology continues to develop, some new PCB wet processing equipment is constantly emerging, such as high-efficiency sandblasting pumps and frequency modulation and voltage regulation devices. The application of these equipment will further improve PCB production efficiency and product quality.
