INTERNALLY DAMPED CIRCUIT ARTICLES

摘要

The present invention provides a method of improving the vibrational damping characteristics of a circuit article. The method involves adding damping layer(s) to the laminate material that is processed into a circuit article. The damping material effectively increases the damping of the circuit article and reduces the amplitude of resonant frequencies of the circuit article excited by environmental vibrations or shocks that the circuit board may encounter in use and thereby potentially improving the performance of the circuit article for vibration and shock related performance issues without the addition of add-on dampers to the circuit articles surface or by isolating the circuit board by means of vibration and shock isolators.
