Abstract
A mechanical strain reduction system include a flexible circuit section of a printed circuit board configured with a meandering shape while in a static state, and a compressible material having a cavity such that the meandering flexible circuit section is positioned within the cavity while the flexible circuit section is in the static state. The flexible circuit section can be part of a rigid-flexible printed circuit board or a flexible printed circuit board. The cavity can be shaped with the same meandering shape as the flexible circuit section in the static state. In general, the cavity is sufficiently shaped to allow positioning of the meandering flexible circuit section within the cavity. Support structures of the same, or different, compressible material can be interspersed within the meander of the flexible circuit section.
