Quick response particle damper for printed circuit boards and planar surfaces
First Claim
1. A particle impact damper for use with printed circuit boards, comprising:
- a housing having one or more separate spherically shaped chambers, each spherically shaped chamber defined by one or more curved surfaces that surround an open cavity of the chamber;
one or more particles, each particle disposed in one of the one or more the spherically shaped chambers, the spherically shaped chamber having a diameter that is at least 7% larger than a diameter of the particle,wherein the one or more particles are configured to move unconstrained within the one or more spherically shaped chambers to contact the one or more curved surfaces to dampen a vibration force applied to the particle impact damper or a component attached to the particle impact damper.

Abstract
An apparatus and system for attaining quick response to vibration damping of a printed circuit board (PCB) or other planar surface utilizing a defined travel displacement of a single spherical tungsten (or other material) ball in a single or plurality of sealed spherical chambers in a particle impact damper (PID). The single spherical tungsten (or other material) ball is not weighed down, constrained, encumbered or influenced by other spherical balls within the chamber; accordingly, providing unrestricted freedom for the ball to quickly respond at the first occurrence of excessive vibrational acceleration over 1G. The structure of a single spherical particle within a sealed spherical chamber also provides a path of minimum distance for the ball to travel before colliding with the ceiling or side walls of the PID chamber. A plurality of spherical chambers can be arranged in a variety of patterns within the PID housing such as desired. The PID housing can be any shape such as a cube, a rectangular cuboid, a cylinder, sphere, triangular tetrahedron, triangular prism, polygon, toroid or any combination of shapes.

10. A particle impact damper, in combination with a printed circuit board, comprising:
-
a housing defining a plurality of separate storage chambers therein; a plurality of spherical particles, each spherical particle disposed and configured to move within one of the plurality of storage chambers; wherein an effective diameter of each of the storage chambers is greater than an effective diameter of the spherical particle disposed in the storage chamber to thereby provide a damping performance of the particle impact damper on the printed circuit board. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
