Abstract
An apparatus for optimizing vibration attenuation of a printed circuit board (PCB) by means of a tunable control for adjusting the volumetric storage capacity, effective mass and travel displacement of a particle impact damper (PID). The apparatus is comprised of a housing with a single or plurality of sealed storage tank(s) containing a payload of tungsten balls (or other materials) with a single or plurality of adjustment screw(s). The volumetric capacity of the storage tank is at maximum when the screw is fully withdrawn from apparatus. The volumetric capacity of the apparatus is reduced when the screw is inserted into the storage tank. The tunable adjustment screw controls the performance of the PID to dampen and attenuate (reduce) the vibration in a printed circuit board without the need to add or remove the payload of tungsten balls inside the particle impact damper.
