Cleaning is a key step in the PCB production process, aimed at removing dust, oil stains, solder residues, and other contaminants from the PCB surface to ensure performance and reliability. The cleaning process typically includes pre-cleaning, main cleaning, rinsing, and drying steps.
Cleaning Process
1. Pre-cleaning
In the pre-cleaning stage, mild cleaning agents or deionized water are used for preliminary cleaning to remove most surface contaminants and prepare for the main cleaning.
2. Main cleaning
Main cleaning is the core of the cleaning process. Special chemical cleaning agents are used through spraying, immersion, or ultrasonic cleaning methods to deeply remove contaminants on and inside the PCB surfaces and holes. This step may be repeated to ensure thorough cleaning.
3. Rinsing
Rinsing is done with deionized water or purified water to remove residual cleaning agents. High pressure or flowing water is usually required to ensure the effect.
4. Drying
Finally, PCBs are thoroughly dried by hot air drying or vacuum drying to avoid water marks or residual moisture affecting PCB performance.

Roles of Magnetic Drive Pumps in PCB Cleaning
Magnetic drive pumps play the following key roles in the PCB cleaning process:
- Chemical solution circulation and transfer – They are used to transfer and circulate chemicals and deionized water used in the cleaning process. Their good sealing performance effectively prevents chemical leakage and protects the work environment.
- Maintaining cleaning effect – By continuously recirculating the cleaning solution, they help maintain the cleanliness and concentration of the solution to ensure consistent cleaning results.
- Energy efficiency – Magnetic drive pumps are usually highly efficient and can provide stable flow and pressure at low energy consumption for long cleaning processes.
- Corrosion resistance – They are typically made of corrosion-resistant materials that can withstand various chemicals used and ensure long-term stable operation.
Advantages of Magnetic Drive Pumps
- Leakage-free – Magnetic coupling eliminates mechanical seals and the possibility of leaks, avoiding chemical contamination.
- Corrosion resistance – Wetted parts are made of quality corrosion-resistant materials.
- Long service life – Simple design with no wear parts results in a long lifetime.
- High efficiency – Rationally designed for energy efficiency.
In summary, magnetic drive pumps effectively circulate and transfer cleaning solutions in PCB cleaning processes to ensure cleaning results while improving efficiency and protecting workplace safety.
