ABSTRACT:
The present invention provides circuit articles which are damped and stiffened relative to resonant vibrations and shock. At least one vibration damping and stiffening member comprising a constraining member comprising a base having at least one projection and a layer(s) of vibration damping material is attached to the circuit article. These member(s) act to stiffen the circuit article and also add significant damping to the circuit article while potentially taking up only a relatively small circuit article surface area.
