Cleanroom on demand


“Clean Multipurpose Cover” is the world’s first flexible cleanroom system

The smallest degree of contamination can lead to major quality issues across many industries. Should, for example, any impurities occur on microchips, space probes and lenses, this can lead to defects or faulty end devices.

To avoid damage, companies tend to outsource the relevant manufacturing and assembly steps for high-quality products to cleanrooms. However, these are expensive, limited in their availability and fail to offer protection against contamination as a result of transportation.

Fraunhofer IPA has now developed the world’s first mobile cleanroom system in the form of its “Clean Multipurpose Cover”. It can be set up flexibly and ensures the sterility of products during transportation.

Particulate impurities and filmic contaminations incur additional costs in many industries. The semi-conductor, food, automotive, air and space exploration technology and pharmaceutical sectors, among others, may be affected by this.

Tanja Meyer, Project Manager at Fraunhofer IPA, explains: “If products become contaminated, they are either rejected or must subsequently be cleaned.” Meyer goes on to clarify that if companies are unable to rely on the cleanliness of their manufacturing environment, retrospective analyses are required. Both are time and cost-intensive.

Companies bypass this problem by manufacturing sensitive products in cleanrooms. However, there are also problems involved in this. Meyer expands: “Not all companies, above all SMEs, have their own cleanroom available. Of course, they can rent one or have the parts cleaned externally, but this is not financially viable over the long term in many cases.”

Furthermore, contamination can still occur during transportation. Static cleanrooms, as they exclusively are these days, cannot protect products outside of their own four walls. With this in mind, scientists at Fraunhofer IPA have already received regular requests from industry to develop a cost-effective, flexible solution.

Companies save energy and maintenance costs

The Stuttgart-based scientists have fulfilled these requirements with their “Clean Multipurpose Cover” solution. The world’s first flexible cleanroom system combines the technical cleanliness standards of a cleanroom with a product which can be set up quickly and simply wherever needed. In being operated “on demand”, the company is not subject to enforced occupancy rates which come with static cleanrooms, thereby making enormous savings in energy and maintenance costs. Another benefit is presented by the swift assembly time of under one hour.

The flexible cleanroom solution can then be used immediately after a short start-up phase. Fraunhofer IPA developed an airflow concept for their system composed of low-TVOC and low abrasion materials with connected filter system.

Meyer explains: “This enables us to guarantee a contamination-free manufacturing environment up to cleanliness class of ISO 3, certified in accordance with DIN ISO 14644-1.” The Clean Multipurpose Cover has a modular structure and can be individually configured as required. It is available in different sizes up to 4m2, with or without a floor. The constructed system can be transported, with a mid-range model weighing no more than 20kg. It is therefore fully functional.

Cleanroom feasibility confirmed in lab tests

In June 2016, scientists at Fraunhofer IPA produced the first prototype. “The tests conducted in the cleanroom laboratories of the Center for Contamination Control affirmed the operational capability of the solution,” Mayer was pleased to confirm. Companies can now order customer-specific models from Fraunhofer IPA.

Our scientists have identified the requirements in exchanges with research and industry partners. Costs are determined on a customer-specific basis, varying according to requirements, size and air purity class. Currently, the Stuttgart-based scientists are working on further developing the system for industry and customer-specific requirements such as chemical and microbiological contaminants.

Im Focus: Space observation with radar to secure Germany's space infrastructure

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.

The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
