We report here on the processing and manufacturing of thin film for printed electronics by microgravure
coating system. The micro-gravure coating systems are consisted of various modules
such as web and system tension controller, micro-gravure coating units, dispenser and hybrid dry
units (UV, NIR, Hot air). Especially, for the optimization of system, the number of idle roller was
minimized and tension isolating infeeder was included. Also, we applied four patterns circle, 45
degree, square and 35 degree for the optimizing coating thickness. The micro-gravure coating
system which applied various patterns to enable continuous coating process and fast coating time
compare with conventional batch coating system. In this paper, introduce of micro-gravure
coating system and testing results of coating thickness (20~700nm), coating time (1~2sec) and
surface roughness (3~12nm) by using micro-gravure coating system.
