CleanControlling is the world's recognized specialist in the field of technical cleanliness and works closely with almost all well-known automotive manufacturers and component suppliers.
CleanControlling Inc. in Charlotte, NC is therefore an important milestone for CleanControlling's sales presence in North America. The focus is on warehousing and distribution of the CleanControlling product range, ensuring short-term and cost-effective availability of specialized products for technical cleanliness in North America. This includes the unique C|PS suction extraction system, for which CleanControllling Inc.is responsible for complete distribution and servie including consulting.
An additional benefit for our North American customers is the microscopic analysis and evaluation of particle traps and stamps on site. This saves time and logistical effort for regular environmental cleanliness monitoring in production proesses.
"Technical cleanliness" means sufficiently low contamination of cleanliness-sensitive technical components with particles that can have a harmful effect on their function. However, corresponding measures are almost never aimed at sterility, but at reducing unavoidable contamination in order to ensure the functionality of technical components.
CleanControlling is your reliable partner for all questions and measures concerning technical cleanliness. The focal points of our consulting services include
We would also be happy to support you with professional assessments of production and assembly facilities or to conduct customized employee training courses on technical cleanliness in your company.
There are two approaches to ensure the required technical cleanliness in production:
The entire production chain must be set up to avoid contamination. Before defining concrete measures to ensure technical cleanliness, like clean rooms, protective clothing or airlocks, it is advisable to determine the current status and carry out a risk assessment from which necessary measures can be derived.
Alternatively, sensitive components can be cleaned at the end of the production chain to remove contamination. However, this only makes sense if the particles cannot cause any damage before and after cleaning. Usually, therefore, both strategies are combined; in this way, even the highest requirements for technical cleanliness can be met.
The set of rules drawn up by the TecSa (Technical Cleanliness) industry association, which also applies in the USA, describes how cleanliness tests must be carried out on products for the automotive industry. Specifically described are
This standard was published as "VDA Volume 19 Testing of technical cleanliness - Particle contamination on functionally relevant motor vehicle parts" and supplemented in 2010 by VDA 19 Part 2 with rules for the cleanliness-relevant alignment of assembly production.
The ISO 16232 standard, published in 2007, is the international counterpart to the German VDA 19 and is fully compatible with it.
In this industry, the demands on technical cleanliness are constantly increasing due to ever smaller and more compact electronic circuits. The ZVEI guide Technical Cleanliness in Electrical Engineering, is therefore specifically tailored to electronics manufacturing. The methods and approaches are described as in VDA 19, but with more detail on important points such as the definition of fibers and particles, and the recommendations for performing and documenting cleanliness analysis.
Other topics covered in the guide include cleanliness-compliant design, environmental cleanliness, data management, and filmic, ionic, and biological contamination (whiskers). A calculation tool also allows a closer look at the risk of electrical short circuits caused by conductive particles.
The international equivalent of the ZVEI guide is IEC TR 61191-7:2020. This part of IEC 61191 deals with the assessment of technical cleanliness in electronics assembly. Described are, among other things, the sources of particle contamination on components and assemblies in the electronics industry, the associated risks, and the analysis, reduction and control of hazardous particles.
