Abstract

The application of inkjet technology has been broadening from home printers to manufacturing tools. Recently, there have been demands for high-resolution printing, especially in the field of printed electronics applications. To improve upon the conventional inkjet printing patterning method, electrohydrodynamic (EHD) inkjet technology has recently attracted attention because droplets smaller than the nozzle diameter can be ejected and materials with wider viscosity range can be used for jetting. In this study, an EHD jet printing system for fine patterning is presented. To print various patterns based on drop on demand printing, vector and raster printing algorithm are implanted in the printing software. Fine conductive patterns with line width of less than $7{\mu}m$ can be easily achieved via EHD jet using a nozzle with inner diameter of $8{\mu}m$.

잉크젯 기술은 가정용 프린터에서부터 제조 도구로 확대 되었다. 최근 인쇄전자 분야에서 고해상도 인쇄가 요구되고 있다. 기존의 잉크젯 인쇄 패터닝 방식을 향상 시키기 위해 전기수력학잉크젯 기술이 최근 주목을 받고 있는데 노즐 직경보다 작은 방울을 토출할 수 있고 넓은 점도 범위와 재료를 사용할 수 있기 때문이다. 본 논문에서는 미세 패터닝을 위한 EHD 프린팅 시스템이다. 요구 적출형 프린팅에 의해 다양한 패턴을 인쇄하고 벡터와 레스터 프린팅 알고리즘을 개발하였다. 내경이 $8{\mu}m$ 인 노즐을 이용하여 $7{\mu}m$ 이하의 미세 전도성 선폭을 EHD 방식을 통해 만들 수 있다.
