AP&S invests in new ultrapure water plant to ensure quality standards

AP&S International GmbH is expanding its infrastructure for ultrapure water treatment, sending a clear signal for the highest quality and security of supply in the semiconductor industry. With the commissioning of a new ultrapure water plant, the company is meeting the increased demand and growi…

Perfect for ultrapure water production: WS Sanitary Housing: The high-gloss polished WS Sanitary housings made of stainless steel are used at the end of the process in ultrapure water production with WFPES-E membrane filter candles as a

Self-standing WTKF stainless steel housings: In combination with depth filter candles, the housings are ideal as pre-filters, particle filters, and fine filters before water treatment systems. An inwardly curved housing bottom facilitates residual drainage. (Photo: Martin Wolf Wagner)

WFPPA and WFMLP pleated elements: With a long service life and an absolute separation efficiency of 99.9% at low differential pressure, the pleated elements meet all requirements for pre- or final filtration in pure water production. (Photo: Martin Wolf Wagner)

Hydrophilic WFPES-E Membrane Filter Cartridges: WFPES-E membrane filter cartridges are already pre-filtered with ultrapure water and individually integrity tested. In filtration fineness from 0.2 μm to 0.04 μm, they are used as final filters for sterilization in ultrapure water production before the ultrapure water is split into hydrogen (H2) and oxygen (O2) in electrolysis. (Photo: Martin Wolf Wagner)

CP- / CP2 Deep Filter Cartridges as Protective Filters: When producing pure water, an ion exchanger is usually used. In the feed line, there is a particulate filter of type CP or CP2. (Photo: Martin Wolf Wagner)

Precision under vacuum: Cleanroom and vacuum technology as the key to new technologies

The vacuum and cleanroom technology go hand in hand and form the foundation of many innovative technologies. Both cleanroom technology and vacuum technology create a controlled environment that eliminates unwanted influences, significantly increasing precision, purity, and efficiency in industrial a…

The process design and definition of the optimal process parameters are carried out in the company's own cleanroom test facility. The preparation of the process media—carbon dioxide and compressed air—ensures air quality that meets the standards required, for example, in semiconductor manufacturing. (Photo credit: acp systems)

The compact, stainless steel JetCell cleaning cell with rotating nozzles was developed for automated cleaning applications and is capable of cleaning large areas in a short time. It can be easily integrated into an interlinked manufacturing environment or operated as a stand-alone device. (Photo credit: acp systems)

With the dry quattroClean snow jet technology, particulate cleanliness in accordance with ORK 1 can be consistently achieved. For film-like residues, the cleaning results are comparable to those obtained with other fine cleaning methods. (Image source: acp systems)

Effective, dry, and cleanroom-compatible cleaning solutions such as the quattroClean snow jet technology are essential to reliably meet the sometimes enormously increased requirements for technical cleanliness in electronics manufacturing or to clean already assembled components.

quattroClean snow jet technology - scalable, inline-capable and cleanroom-compatible

Dry cleaning process for optimum cleaning results in electronics production

Whether energy, mobility or industry - electronic components and systems play a key role in the transformation towards climate neutrality. Due to higher demands on power density and reliability as well as new solutions, the requirements for technical cleanliness during the production of these compon…

Changed cleanliness requirements in type and quantity require different testing methods. In addition to technically complex and time-consuming procedures (e.g., XPS, ATR/FTIR, TOF-SIMS, etc.), UV light inspection has proven to be a quick method that makes even the smallest particles or fibers visible.

Insight into the TDZ: Cleaning components before or within the cleanroom has become routine in recent years. (Photo/Graphic: LPW)

Nothing enters the cleanroom without pre-cleaning to avoid any contamination. (Photo/Graphic: LPW)

The LPW pure water supply unit for the final rinses in the TDZ represents another important component in ensuring process quality. (Photo/Graphic: LPW)

The quality of the cleanroom air concerning particulate contamination and turnover frequency is maintained in a recirculation filter system and controlled via process data monitoring (including particle counters). (Photo/Graphic: LPW)

The cleaning system can contribute to recontamination, not only during the cleaning process itself, but also through unintended cross-contamination of the product. The maintenance area is also often a source of this and is therefore always placed outside the cleanroom in LPW systems. (Photo/Graphic: LPW)

Industrial cleaning technology in high purity environments

A cleanroom alone does not ensure cleanliness

When it comes to industrial cleaning technology, applications in or before cleanrooms are increasingly being discussed — and not only in the medical and semiconductor segments. However, there is sometimes the impression that simply combining a cleaning system with a cleanroom provides the solution…

Safeguarding hospitals and healthcare centers with vaporized hydrogen peroxide

Iacobus is the Greek variant of the Hebrew word meaning “held by the heel”, but the original definition is thought to come from an Aramaic phrase for “may God protect.” Founded in 2014 in Łódź, Poland, Iacobus Sp z.o.o offers decontamination services and equipment. Iacobus also services a…

Other specialized areas are thus accredited according to DIN EN ISO/IEC 17025 for testing research, industrial…

The Xelum R&D, consisting of a feeder-blender unit and the Solidlab 2 Plus, offers a flexible platform for developing continuous manufacturing processes and easily transferring them to production scale – without scale-up.

The compact TPR 200 Plus tablet press supports the efficient production of small and medium-sized batches, thanks in part to an integrated Data Acquisition System (DAQ) for determining tablet quality and process stability.
