전자 부품 제조를 위한 왁스 패터닝 오프셋 인쇄에 관한 연구

Abstract

Traditional offset lithographic printing method is one of the most promising high speed, roll to roll techniques in printing industries. Because of the dot gain and irregular ink penetration onto the paper materials, it has been unsuitable to use to produce the printed electronics. In order to realize the fine lines, we proposed the wax patterning printing method and were experimented using by nano particle silver paste ink on the wax patterned paper to improve printing quality and high conductive lines. Instead of coating method a new ink lithographic printing process was introduced to fill the trench patterns with the high viscous paste ink. In this research, we demonstrated that high viscous paste ink with trench pattern is suitable for printing fine lines by studying specific printing parameters. The wax patterning and printing conditions were subsequently researched to obtain uniform and fine lines. High conductive lines with of resolution were formed based on the this method that resulted from offset lithographic printing process.
