Why is ultrasonic cleaning used for PCB cleaning?

Advantages of ultrasonic cleaning PCB:

Compared with other cleaning methods, ultrasonic cleaning machine shows great advantages. Especially in specialized and collectivized production enterprises, ultrasonic cleaning machines have gradually replaced the traditional process methods such as soaking, brushing, pressure cleaning, vibration cleaning and steam cleaning. The high efficiency and high cleanliness of ultrasonic cleaning machine benefit from the penetration and cavitation shock wave generated by its sound wave when it propagates in the medium. Therefore, it is easy to clean the parts with complex shapes, holes and gaps. For general degreasing, rust prevention, phosphating and other processes, it only takes two or three minutes under the action of ultrasonic waves, which can increase the speed by several times to dozens of times compared with traditional methods, and the cleanliness can also reach a high standard. It can be seen that in many occasions with high requirements on product surface quality and productivity, other treatment methods are difficult to achieve or irreplaceable.

To sum up, ultrasonic cleaning is the best choice for PCB cleaning.
