An Investigation onto Polydimethylsiloxane (PDMS) Printing Plate of Multiple Functional Solid Line by Flexographic

Abstract

Recently low cost production is vital to produce printed electronics by roll to roll manufacturing printing process like a flexographic. Flexographic has a high speed technique which commonly used for printing onto large area flexible substrates. However, the minimum feature sizes achieved with roll to roll printing processes, such as flexographic is in the range of fifty microns. The main contribution of this limitation is photopolymer flexographic plate unable to be produced finer micron range due to film that made by Laser Ablation Mask (LAMs) technology not sufficiently robust and consequently at micron ranges line will not be formed on the printing plate. Hence, polydimethylsiloxane (PDMS) is used instead of photopolymer. Printing trial had been conducted and multiple solid lines successfully printed for below fifty microns line width with no interference between two adjacent lines of the printed images.

Characterization of Multiple Functional Solid Line of Graphite Ink Surface Printed by Micro-Flexographic

“…In order to develop the electronic devices or biosensors to a smaller size, it is very important to have printed functional ink in the micro-scale. Here, a customized bench press flexographic printing machine using PDMS printing plate has been studied [3][4][5]. PDMS is well known as printing plate for patterning micro even nano-scale in the micro-contact printing [6].…”
