Abstract
In order to limit the stress and strain applied to a printed circuit board while still maintaining flexibility, a flexible section of the printed circuit board is configured to have a non-linear portion that functions as a hinge when the flexible section is bent, flexed, twisted or otherwise subjected to a motion related force. The hinge configuration improves durability and flexibility while minimizing ripping and cracking of the printed circuit board, particularly interconnects within the flexible section and a transition region between the flexible section and a rigid section of the printed circuit board. The hinge is configured to have a non-linear shape, such as a serpentine or circuitous path that can include curved portions, different linear portions or some combination of curved and linear portions.
