New 250 kHz ultrasonic generator from Weber Ultrasonics. Careful And Efficient Cleaning Of The Most Sensitive Substrates
Using ultrasonic components tailored to suit requirements, Weber Ultrasonics makes it possible to build effective and economic ultrasonic cleaning units for all cleaning tasks
Weber Ultrasonics GmbH was founded by Dieter Weber in 1998 and is based in Karlsbad-Ittersbach in the German region of Baden. Thanks to its high quality, innovative products for ultrasonic cleaning, ultrasonic welding and special applications, Weber Ultrasonics has become one of the world’s technological leaders in the space of just a few years and develops and produces customer-specific ultrasonic solutions alongside its standard products. The ultrasonic component manufacturer is certified in accordance with DIN EN ISO 9001:2000 and serves small, medium-sized and large customers from many sectors, including the automotive industry, sanitary engineering, clock-making, electrical engineering and electronics, precision mechanics and optics, surface and cleaning technology, metal processing and PCB manufacture. Two new subsidiaries were founded in 2009: Weber Ultrasonics America and Weber Ultrasonics weld & cut GmbH. Together with its strategic alliance partners, Weber Ultrasonics has bundled the extensive ultrasonic competence of all business partners involved, concentrating it in the new companies at an international level for the areas of ultrasonic welding and cleaning.
Karlsbad – Ultrasound offers decisive advantages in the cleaning of components and surfaces. The increasing miniaturisation of components and ever more delicate structures and sensitive substrates requires ultrasonic cleaning systems which guarantee particularly careful, reliable and reproducible removal of film and particulate contamination. Weber Ultrasonics has developed an innovative 250 kHz ultrasonic generator with a power output of 250 and 500 Watt as well as transducers matched for these applications. The new ultrasonic system allows the realisation of highly efficient, top-quality cleaning systems which are tailored to suit requirements and offer a high level of process safety.
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, as the lower the frequency of the electrical signals, the more energy is released by the ultrasonic waves. When working with sensitive components and fine structures such as those commonly found in the optical and semiconductor industry, electronics, precision mechanics, microtechnology and photovoltaics today, 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, Weber Ultrasonics GmbH has added a 250 kHz frequency module generator to its proven SONIC DIGITAL digital ultrasonic generator programme. The new 19" device from the Karlsbad company, one of the world’s leading manufacturers of ultrasonic components, is available with a power output of 250 and 500 Watt. Its high efficiency, compact design, convenient operation and sophisticated features for maximum process and operational safety give it the edge over the competition.
Constant power output for an optimum cleaning result
The frequency is generated and controlled digitally, allowing the new 250 kHz module generator to also offer maximum stability of all parameters relevant to the process, such as frequency, amplitude and power output and therefore greater efficiency. The power output can be set steplessly 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 via remote control.
Maximum process and operational safety through innovative protective functions
The varied features offered as standard by the SONIC DIGITAL series guarantee a maximum of process and operational safety. This includes an intelligent cooling system as well as protection mechanisms against short-circuiting, no-load operation, overloading and overheating.
Ideally matched high performance transducer systems
Another advantage is that the generators by Weber Ultrasonics can be operated with every compatible transducer system of the same power class. SONOSUB submersible transducers and SONOPLATE plate transducers with 250 and 500 Watt power output, the dimensions of which can be adapted according to customer requirements or the object to be cleaned, can be used with the 250 kHz generator, thus further improving the efficiency of the cleaning system.
