Laser micro-patterning software development for manufacturing of pattern roll for printed electronics

In this paper, laser micro-patterning software developed for manufacturing of printing rolls for printed electronics is presented. The software consists of a servo control module, an image processing module, a configuration module, and a laser patterning module. By the software, laser beam´s position and irradiation are controlled according to drawing patterns while the pattern roll is rotating. In this operation, control performance is important to determine the quality of the pattern roll and manufactured electronics after printing. The software is developed based on the accurate control algorithm and optimization of laser operation over the whole image for computation time and high-speed patterning. Additionally, overlapping image patterning is considered for the uniformity of the engraving depth and patterning quality.
