High-purity cleaning: hype or reality?

Engineer Live News Desk

The cleanliness requirements for high-tech components are becoming increasingly stringent. As a result, in addition to the terms “ultra-fine” and “precision cleaning”, the term “high-purity cleaning” has become established in recent years. But what is behind it and what are the differences between the three terms? These questions will be addressed at this year's parts2clean fair, featuring the highlight topic of “High Purity”. This complements the classic core areas covered at this, the leading international trade fair for industrial parts and surface cleaning, which will be held from 26 – 28 September 2023 at the Stuttgart Exhibition Center in Germany.

The enormously amplified and continually rising demands on the reliability and performance of parts and components also have an impact on component cleaning. This affects industries such as the semiconductor supply industry, electronics manufacturing, electric mobility, precision optics, the optoelectronic industry, sensor technology, photonics, thin-film technology, vacuum, laser and analysis technology,aerospace, and medical and pharmaceutical technology. In these industrial sectors, the term “high purity” is increasingly being used. “Despite the comparatively recent discussion about this area of application for industrial component cleaning, parts2clean has already taken it up through its exhibitors, who have a wide variety of solutions on offer,” explains Christoph Nowak, Project Director at Deutsche Messe.

In order to remove even the tiniest impurities, it is necessary for the equipment and cleaning technologies used – wet-chemical processes with solvents and aqueous media, dry cleaning with, for example, CO2 snow jets, plasma cleaning and vacuum bakeout systems – to be appropriately designed and constructed, and adapted to the specific cleanliness requirements of the components. In the case of wet-chemical processes, this also applies to the cleaning media and water qualities involved.

Another aspect involves the clean handling of the already cleaned parts. For this reason, the components are cleaned or discharged into a cleanroom in accordance with the applicable cleanliness specifications. “High Purity” also a hot topic at international Expert Forum “As the leading trade show for industrial component cleaning, we aim not only to be a reflection of the market, but also to drive the professional communication of tomorrow's topics,” emphasizes Christoph Nowak. “The topic of high purity will therefore be explored in greater depth in the bilingual Expert Forum.” The well-balanced program of this knowledge forum, which is organized jointly with the Fraunhofer Cleaning Business Unit and the Industrial Parts Cleaning Association (FiT), Fraunhofer Cleaning Business Unit and the Industrial Parts Cleaning Association (FiT), ensures that information on classic cleaning topics, current tasks and developments from a wide range of industrial sectors will not be neglected. These presentations by renowned speakers from science, research and industry will also be simultaneously translated (English <> German). “For national and international visitors, parts2clean thus enables a targeted transfer of knowledge about trends, innovations and benchmark applications in all areas of industrial parts cleaning,” reports Nowak.
