A mechanical-shock-mount assembly enables attachment of a mechanical-shock-sensitive electronic device to a support structure. Two identical shock-mount structures are attached and located on opposite sides of an electronic device. Each shock-mount structure has a pair of generally planar spring-like cantilever beams that have their free ends for attachment to the support structure. Damping material is located on the surfaces of the cantilever beams between the beams and clamping surfaces. At least one clamping surface is a plate that compresses the damping material between itself and the beam and/or compresses the damping material between the beam and a surface of the support structure when it is attached to the support structure. This shock-mount structure acts as a highly-damped nonlinear spring system that provides mechanical-shock resistance for the device in a direction perpendicular to the cantilevered beams and high stiffness in a direction in the plane of the beams. If desired, the shock-mounts can be first assembled to the support structure before attaching the device. The support structure can optionally have additional features for attaching other components of the device host.
