Optimized slot dies for electronic products
When designing new products in the field of flexible electronics, with the examples of organic photovoltaic (OPV) and organic LED’s (OLED), the appropriate components of the coating liquids are often only available in very limited quantity and correspondingly expensive. Thus, the filling volume of the entire system is very important to allow for economic development. Also, the application of a uniform, only a few micrometers thin wet layer, with a simple manual procedure is not possible. In order to ensure the scale-up from the laboratory in a subsequent «Roll-to-Roll» process, the same application process should be used from the beginning, as it is most promising for a later production. This requires bridging the gap between the labscale of the development laboratory on one hand and industrialized, well proven coating processes on the other hand. For this purpose TSE has developed a modular coating system which allows to coat onto individual “sheets” with an optimized slot die in lab-scale.
