Ultrasonics Deliver Efficient Cleaning of Sensitive Substrates

Ultrasound allows parts to be cleaned within short cleaning cycles, and in line with demands in an economical, reproducible, and environmentally-friendly manner for coarse, fine, and superfine cleaning. The frequency of the electrical signals emitted by the ultrasonic generator, which the transducer system transfers to a tank of liquid as waves of ultrasound, is the key factor for the cleaning effect. The lower the frequency of the electrical signals means that more energy is released by the ultrasonic waves. When working with sensitive components and fine structures, a frequency that is too low can damage the parts or destroy the structures.

In order to complete such demanding cleaning tasks, safely and reliably, a 250kHz frequency module generator has been added to Weber‘s Sonic Digital, a digital ultrasonic generator programme. The 19" device is available with a power output of 250W and 500W. Overall, the ultrasonic system allows the realization of highly efficient cleaning in a system that is tailored to suit necessary requirements and offer a high level of process safety.

Constant Power, Optimum Results
The frequency in the Sonic Digital is generated and controlled digitally, allowing the 250kHz module generator to also offer maximum stability of all parameters relevant to the process – such as frequency, amplitude, and power output – in turn delivering greater efficiency. The power output can be steplessly set between 10% and 100% via power control. This, together with the high grade of efficiency, ensures a cleaning process with reproducible results at minimum cost, which also meets requirements in terms of both the object to be cleaned and the level of soiling. The device can be operated manually on the equipment itself or by remote control.

The varied features offered as standard by the Sonic Digital series guarantee a maximum of process and operational safety – including an intelligent cooling system as well as protection mechanisms against short-circuiting, no-load operation, overloading, and overheating.

Another advantage is that the generators can be operated with every compatible transducer system of the same power class. Sonosub submersible transducers and Sonoplate plate transducers with 250W and 500W power output, the dimensions of which can be adapted according to customer requirements or the object to be cleaned, can be used with the 250kHz generator, further improving the efficiency of the cleaning system.
