Particle Impact Dampers reduce random vibration in PCB assemblies in harsh environments.

Is a mechanical component that surface-mounts on the PCB. Inside the PID is a payload of freely-moving tungsten balls that move in the opposite direction to the board. This counter motion pulls back the bending of the board and attenuates 10db of vibrational energy. PID technology works at fundamental mode vibration frequencies of 100Hz to 2KHz, and operates over a full range of temperatures without derating. COTS standard solution is suitable for retrofitting and hardening heritage hardware in the field. Can be solder-attached like ordinary components, or attached to the board using permanent epoxy adhesive.
