Two common industrial PCB cleaning methods are ultrasonic cleaning and spray cleaning.
Ultrasonic Cleaning
Uses high-frequency waves to remove contaminants.
Pros:
- Deep cleaning capability
Cons: - May damage sensitive components
Spray Cleaning Machine
Uses high-pressure spray with cleaning solution.
Pros:
- Safe for PCBA
- Consistent results
- High efficiency
Conclusion
For SMT applications, spray-type PCBA cleaning machines are widely preferred.
