The Role of Magnetic Drive Pumps in the PCB Cleaning Process


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.
