Cleanliness & Cleanrooms for Electronics-Based Systems’ Production and Products

Although the necessity for clean environments is quite salient in many fields, there is still little clarity about the exact definition of “cleanliness” and the related production, product and working requirements for each application and area of activity, be this the production of electronic components, optical equipment, medicine and hospital, the manufacturing and processing of beverages and food, etc.

Starting from this observation, the Silicon Alps cluster focus group “Cleanroom and technology” dedicated a 1-day workshop on 23.05.2019 to the goal of creating a common understanding and definition of cleanrooms and cleanroom technologies as wells as of the related decision processes and flows, particularly for microelectronics/mechatronics/ electronics.

The intensive expert discussions have been based on the analysis of real-life positive and negative experiences with the planning and implementation of cleanrooms,  respectively the matters of human behavior and training.  The better and more time-intensive cleanroom planning as well as the focused training of the involved staff have emerged as the most important and urgent matters.

The task of defining cleanliness itself has testified the diversity of perspectives and the difficulty of creating  a simple “common language” in this field. Basically understood as “as little as possible particles or germs in the air or on the surfaces”, cleanliness has also been  associated with dimensions and requirements such as:  “high norming”, “difficulty of prediction”, “different meaning according to the application field”, “correct behavior” and “cleaning: manual, chemical, disinfection, filtering, thermic”.

The intensive discussions about the interaction betwenn the cleanroom specialist and customers have resulted in the development of a  “cleanroom decision matrix” general model. This will help companies, particularly the new ones starting to deal with the topic to put the right questions/formulate their requirements in the right order. This matrix will be further developed and fine-tuned in the following months and made available to the Silicon Alps Cluster Ecosystem.

The Silicon Alps Cluster warmly thanks the participating experts for their engagement and valuable ideas and suggestions:
