Flexible technology for individual needs

Our multi-stage immersion-type ultrasonic cleaning lines meet the highest standards of substrate cleanliness. Their sophisticated modular design allows these systems to be individually and cost-efficiently adapted to any application and requirement. This includes sputtering, ultrasonic resonators for different frequencies and power levels as well as re-circulation and filtration systems. Various processes, including passivation, DI rinsing, lift-out, and drying (blowing off, warm air, vacuum, IR) are applied to meet the specific task.

Comprehensive know-how and experience

To fully benefit from a cleaning system, achieve the required cleaning quality and work economically and environmentally friendly at the same time, extensive know-how is required. With a considerable reference list of renowned customers including manufacturers of precision optics such as lenses or mirrors we can rely on our long-term experience in this industry field.

High Purity Test Center for cleaning trials

At our Technology Centers, our customers can gain hands-on experience of a wide variety of cleaning and drying systems. Trial runs with original parts are carried out under production conditions to determine the optimum process for an effective, economical, and energy-efficient solution for your cleaning tasks. In 2022, we have opened an additional High Purity Test Center in Dettingen (near Stuttgart, Germany) especially for customers with highest demands on component cleanliness.
