Within the ultrasonic technique, machines are available in different frequencies and capacities. Not every frequency is good for every application, so it is important to check in advance what you mainly want to clean. By adjusting the power and frequency to your object, better results can be achieved, so you get more out of your cleaner.
At a frequency of 25 kHz (hard brush) the air bubbles are larger than when talking about a 50 kHz frequency (soft brush). The lower the frequency, the deeper and stronger the cleaning.
In the case of printed circuit boards, a higher frequency is more comfortable or an ultrasonic with adjustable power, such as the Sonorex Super, Digiplus or the GeneralSonic. We supply cleaners with the most common frequencies from stock, such as 35 kHz, 40 kHz, 25 kHz or 25&40 kHz for industrial cleaners (bottom and side vibration).
