Flux residue on circuit boards can lead to short circuits, signal interference, and even damage to components, negatively impacting the performance and reliability of electronic devices. Therefore, timely cleaning of flux residue is crucial.
Different methods for cleaning circuit boards.
- Alcohol cleaning: Using isopropyl alcohol to wipe PCBA circuit boards manually.
- Ultrasonic cleaning: Utilizing the action of microbubble implosion generated by ultrasonic vibration to effectively dissolve and remove flux residue from the circuit boards.
- Airflow cleaning: Removing flux residue from the surface of the circuit boards by high-pressure gas jetting and quickly drying them. Silman Tech’s intelligent DEZ-C743 circuit board cleaning machine is recommended.
What are the pros and cons of various cleaning methods?
- Alcohol cleaning: Simple and readily available, low cost, but the cleaning effectiveness may not be as good as other methods, and it has some environmental impact.
- Ultrasonic cleaning: Able to clean deeply into fine areas, requires the use of chemical solvents, and the cleaning effectiveness may vary, but the equipment cost is relatively low.
- Airflow cleaning: Fast operation, environmentally friendly, good cleaning effectiveness, but attention needs to be paid to quality control during cleaning.
