    Abstract: A circuit board comprises one or more rigid sections, one or more flexible sections, and one or more transition areas where the circuit board transitions from the rigid section to the flexible section. One or more mechanically restrictive components are applied at a transition area to prevent failure and/or breakage of the circuit as it is bent and flexed. The mechanically restrictive components can be dispersed throughout the circuit as a coverlay, an underlay, and symmetrically positioned within the circuit board as an overlay and an underlay.

    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.

    Abstract: In order to limit the stress and strain applied to a printed circuit board while still maintaining flexibility, multiple small rigid mesas are formed on a flexible printed circuit, where the rigid mesas are physically isolated by trenches formed around their perimeters. Individual electronic components are attached to the multiple rigid mesas. These trenches form openings at which the printed circuit board is enabled to flex, bend or twist, thereby minimizing, if not eliminating, resulting stress applied to the interconnection between the electronic components and the rigid mesas.
