The first group comprised cleaning workers and the second group included production workers.
Applying the previously defined criteria, we prioritized ingredients among the large number of ingredient comprising cleaning mixtures.
The PVD technology of the pilot line comprises different plasma cleaning processes, thermal evaporation by means of radiation heating as well as electron beam evaporation.
This comprised data cleaning, data validation, and sorting.
Exemplarily, coating or adhesive bonding processes rely on a sequence of layer-oriented procedures comprising substrate cleaning, pre-treatment and, finally, the application of a fluid system which during the manufacture wets the substrate surface, hardens and forms a coating or an adhesive layer [1-4].
