  • CIRCUIT BOARD WITH REGIONAL FLEXIBILITY
    Publication number: 20080105455
    Abstract: The present invention provides a printed circuit board (PCB) adapted to reduce stress due to coupling of a structure to two different areas of the PCB. The invention involves mechanically isolating an area of the PCB intended for coupling with the structure by forming a stress-relief region around the area in order to create a localised movable area. By introducing such localised flexibility into the PCB in at least the area of one coupling, any build-up of stress due to the coupling of the structure can be mitigated.
