The patented slot die coating system was developed in SAM's SPEL - Sungan Printed Electronics Laboratory (SAMLab 1). The system is designed to achieve thin and uniform coating profiles and monitor the meniscus of the slot die in real time. It also monitors and controls the alignment of overlay coating stripe patterns in stripe coating.
According to SAM, the design inside the slot die cavity ensures a thin, uniform coating profile while an integrated process monitoring system maximizes product quality and consistency. On-line cameras monitor the meniscus in real time as well as the alignment of overlay stripe patterns. This development is intended for process repeatability and minimization of the required operating skill.
Applications include functional coatings on packaging substrates and electronics, optical films, barrier films, printed electronics and fuel cells.
