How To Clean A Corroded Circuit Board

By | April 26, 2023



Have you ever wondered how to clean a corroded circuit board? Corrosion on a circuit board can cause unreliable connections and can even lead to dangerous electrical arcs. Fortunately, there are methods of cleaning the corrosion off and restoring it back to its original condition.

The best method of cleaning a corroded circuit board is to use an ultrasonic cleaner. This type of cleaner uses sound waves to agitate the corrosion, which helps to loosen it and make it easier to remove. The process is simple: Just submerge the board in the cleaner and turn it on. The sound waves will help to break down the corrosion, allowing you to easily wipe it away with a soft cloth. Additionally, an ultrasonic cleaner can be used to clean other components, such as connectors, which can be difficult to clean in other ways.

If you don't have access to an ultrasonic cleaner, you can also use a mild detergent and water to clean the board. Use a soft brush to gently scrub the board, taking care not to damage any of the components. Once you've removed the corrosion, rinse the board with clean water and allow it to air dry before reassembling.

Cleaning a corroded circuit board can be a daunting task, but it's important to do it correctly to ensure reliable performance and safety. By using an ultrasonic cleaner or a mild detergent and water, you can easily restore your board back to its original condition and enjoy years of reliable performance.
