잉크젯 프린팅 기술을 이용한 기판 표면처리와 금속 패턴 형성에 관한 연구 = Contributed A Study of Substrate Surface Treatment and Metal Pattern Formation using Inkjet Printing Technology

다국어 초록 (Multilingual Abstract)

Inkjet printing is one of the direct writing technologies and is able to form a pattern onto substrate by dispensing droplets in desired position. Also, by inkjet technology manufacturing time and production costs can be reduced, and procedures can be more efficient. To form a metal pattern, it must be harmonized with conductive nano ink, printing process, sintering, and surface treatment. In this study, micro patterning of conductive line has been investigated using the piezoelectric printhead driven by a bipolar voltage signal is used to dispense 20-40 μm diameter droplets and silver nano ink which consists of 50 nm silver particles. In addition, hydrophobic treatment of surface, overlap printing techniques, and sintering conditions with changing temperature and times to achieve higher conductivity.
