Complex vacuum coating systems for the production of multilayer coatings using PVD offer a variety of parameters for process optimization. An important factor for achieving the best productivity is the maximum deposition rate of the roll-to-roll PVD process. The wrinkling of the substrates due to stress during the coating process has a limiting effect. Different polymers require individual parameterization of the system.
The lecture presents the possibilities of system technology to increase productivity. Based on several examples, results for the best parameterization of the system for optimized coating deposition will be discussed.
