Abstract
A printed circuit board (PCB) incorporates at least one damping layer or section. The at least one damping layer is incorporated in the PCB to absorb vibrations or oscillations that may be conveyed to the PCB. Such vibrations or oscillations may be generated by one or more electrical components coupled to the PCB. The damping layer is disposed to prevent the PCB from audibly vibrating when the electrical components associated with the PCB are caused to vibrate or pulsate under a voltage load.
