Second large cleaning system for Trumpf

The requirements in the High Purity sector of industrial parts cleaning are becoming increasingly complex – and thus also the demands on equipment manufacturers. LPW Cleaning Systems GmbH is a sought-after partner in this field and has now built the second large-scale cleaning system for Trumpf Laser and System Technology in Ditzingen.

In the customized High Purity system with cleanroom connection, components for assemblies in optical assembly will be cleaned in the future. The template was the sister system delivered in 2018 for EUV manufacturing, which has reliably fulfilled its high-purity tasks ever since.

Thus, the design of the new system was also based on the PowerJet model. It is equipped with three treatment chambers and six rinse tanks, whose cleaning and rinsing processes rely not only on traditional methods (spray cleaning, pressure flooding processes, multi-frequency ultrasound) but also on the patented Vacuum Pulse process of Cyclic Nucleation (CNp) introduced this year.

Furthermore, the newly developed ULTRA working chamber for ultra-clean processes has been integrated. Drying is ensured through a combined vacuum-infrared technology with minimal re-/cross-contamination. Additionally, the system is connected via fully automated feed automation with adapted laminar flow units directly to the cleanroom at Trumpf through LPW cleanroom pass-throughs. The return line for empty load carriers is included in the overall automation.

For this project, the application engineering team of the Riedlingen cleaning specialists was also particularly in demand regarding energy efficiency optimization and in terms of infrastructural integration and implementation. Since the PowerJet is located on two different floors within the Trumpf building, it had to be separated accordingly.

LPW Managing Director Gerhard Koblenzer: “Not only the conception, delivery, installation, and commissioning of the system are fundamentally challenging for all project participants. Integration into the digital and infrastructural environment – even during the planning phase – is equally an intensive process. Only with a high level of project competence on both sides can such complex tasks be successfully implemented.”
