Wet chemical ultrasonic cleaning with solvents, modified alcohols, or aqueous media provides for a broad field of application in the field of electronics production. Thus, particles, flux material residua, and other film-like contaminations can be removed from metal electronic components, printed circuit boards, wafers, and more. Along with the cleaning medium, the frequency of the electrical signals generated by the ultrasound generator is decisive for the cleaning effect, at which the oscillating system transmits these signals as sound waves into the liquid bath. In this, the following is generally applicable: the lower the frequency of the electrical signals, the higher the energy released by the sound waves.
