Using ultrasonic cleaning machine to clean the circuit board is a good way to clean out the circuit board as bright as the new, the use of ultrasonic principle, the electrical energy into mechanical vibration to produce high-pressure bubbles, the use of bubble burst force detergent particle impact Circuit board. When cleaning the circuit board should pay attention to the correct choice of ultrasonic power, not in the cleaning process to adjust the ultrasonic power is too large, the power and the volume of the container, the amount of cleaning circuit board is generally proportional to the choice of how much ultrasound to be based on The amount of cleaning circuit board, generally only suitable for high-volume circuit board, the circuit board used to clean the solvent can generally be used in the cleaning circuit board should be careful not to clutter, orderly set in the tank body, messy Stacking affect the cleaning effect. Use of solvents for organic solvents, circuit boards for cleaning agents or environmentally friendly electronic ultrasonic cleaning agent, should not use anhydrous ethanol (anhydrous alcohol), otherwise the circuit board will be white, commonly known as white spots.
