점탄성 물질의 임프린팅과 순간회복에 대한 컴퓨터 시뮬레이션 연구

Abstract

Imprinting process for printed electronics was computer simulated. Imprinting technique refers to a technique of putting pressure with a hard stamp and imprinting desired shapes on flexible substrates like film, which enables production of flexible electronic equipment bent by filling metals in various kinds of imprinted flexible substrates. It can form patterns inexpensively in terms of process and device stability compared to the process of manufacturing embossed patterns. This method is the basic technology of manufacturing printed electronic equipment. However, since currently, physical measurement of flow characteristics of viscoelastic substance was impossible, the conditions of the process were calculated through a computer simulation. The results of this study came out using polyflow software for flow analysis. The results of the simulation of instant restoration in this imprinting will be an advantage in finding the optimum conditions in the technology of printed electronics in the future, and it is expected that they will be useful for flow analysis of ink in continuous roll printing.
