Abstract
Surface mounted ceramic capacitors (14) on printed circuit boards (10′) are subject to vibrations (18) caused by the piezo effect. Other electronic components are subject to magnetostriction and likewise generate vibrations. In prior art, the vibrations can propagate (20) on a printed circuit board (10). To suppress the propagation of the vibrations caused by the electronic component (14), the invention provides at least one slot (22) in the printed circuit board (10′). The slot (22) extends, for example, parallel to a side wall of the electronic component (14).
Claims8
A printed circuit board (10′), on which at least two conductor tracks (12) are arranged, to which an electronic component (14) is connected which triggers oscillations (18) during operation, characterized by at least one slot (22) formed in the printed circuit board (10′) for preventing the propagation of oscillations (20) triggered by the electronic component over the printed circuit board.
