Abstract

The roll-to-roll (R2R) printed electronics system is one of the most promising technologies for the printed electronics industry because of several advantages in terms of productivity and cost. In the R2R printed electronics system, the characteristics of the printed patterns are an important issue that determines the functional quality of the printed matter. This study analyzed how several main factors may affect the characteristics of printed patterns, especially the thickness and surface roughness. The statistical model for estimation of the printed pattern was developed as a function of the main factors using the design of experiment (DOE) methodology. Based on the statistical analysis results, the R2R printed electronics system can be designed to control the characteristics of printed patterns.

롤투롤 인쇄전자 시스템은 높은 생산성과 낮은 원가를 이점으로 인쇄전자 산업에서 가장 각광을 받고 있는 인쇄기술 중 하나이다. 이러한 롤투롤 인쇄전자 시스템에서 인쇄패턴의 특성은 인쇄물의 기능적 성질을 결정짓는 중요한 문제라 할 수 있다. 따라서 본 연구에서는 인쇄패턴의 특성을 결정짓는 주요 인자들이 특별히 인쇄패턴의 두께와 표면 조도에 미치는 영향성에 대한 분석이 수행되었다. 실험계획법을 적용하여 인쇄패턴의 두께와 표면조도에 대한 각 인자의 주효과 및 교호작용 효과를 정량적으로 제시하였고, 분산분석을 통해 유의한 인자를 찾아내었다. 또한 이에 따르는 통계적 모델이 주요 인자의 함수로서 개발되었다. 이러한 결과는 롤투롤 전자인쇄 시스템의 특징에 따라 요구되는 인쇄패턴의 특성을 얻는데 활용될 수 있을 것이다.
