The inventive shock damping system for vibration sensitive surface mounted devices consists of an elastomeric material having conductive fiber material disposed between a printed circuit board (PCB) and a surface mounted device. Once disposed between PCB and surface mounted device, the elastomeric material, the PCB and the surface mounted device are compressed together with a component restraining system, to provide a secure electrical connection between one or more interconnect pads conductively attached to surface mounted device and the PCB. The elastomeric material allows signals and current to flow between surface mounted device and PCB without the use of any attached wires or leads while at the same time providing a system for damping any shocks or vibrations that may be transferred to surface mounted device through the PCB or through the protective component restraining system that encloses the device and the elastomeric material.
