Predicting the properties of flexible printed circuits
(FPCs) before production is a significant challenge in their
development. Traditional design flows model FPCs in a flat state,
yet simulations of the actual bent shape of the circuits are more
effective in forecasting their behavior in real-world applications.
Currently, only proprietary tools are available for simulating
these 3D geometries, with no open-source alternatives. This paper
introduces a novel open-source software tool that bridges this gap
by transforming two-dimensional layout data from KiCad files
into three-dimensional bent geometries. This transformation is
achieved through segmentation and meshing techniques, enabling
accurate verification of circuit parameters via simulation. The
software facilitates these simulations by generating the necessary
input files, thus supporting a comprehensive open-source design
and verification workflow. This work not only enhances the
accessibility of FPC design and simulation but also underscores
the broader applicability of open-source solutions for printed
circuit board design.
