Abstract
A printed circuit board includes vibration areas where vibration sensitive components of an electrical circuit design fabricated on the printed circuit board are mechanically isolated from supporting circuitry. The present invention provides a printed circuit board with areas having an increased natural resonant frequency of vibration for the circuit board area where the vibration sensitive circuit is located. The printed circuit board comprises a number of slots, holes or other openings around the vibration sensitive circuitry. In addition, one or more circuit board conductive paths are provided for maintaining electrical conductivity between the isolated circuit and the supporting circuits.
