Parametric optimization of metal conductors in flexible electronics design
Abstract
Purpose
The purpose of this paper is to illustrate the dependence of flexible-electronics properties on the metal conductor parameters, such as the width, thickness, connection length and inner meander radius of the conductor.
Design/methodology/approach
This paper uses the finite element method to simulate flexible electronics with a copper conductor attached to polyimide substrate under tension, by using different parameters of the conductor.
Findings
By careful variation of copper conductor parameters, the authors obtain an optimized structure that can undergo large deformations with small stress concentrations, lending convenience for packaging.
Originality/value
The authors have developed an optimization method for selecting metal conductor parameters in flexible electronics.
