Use of an Adaptive Phononic Crystal to Induce Wipe in ZIF Connectors

A good contact system needs an adequate amount of wipe for reliable performance. Wiping clears away unwanted contaminants. Some contact systems, for example LGAs, do not have much wipe. However, a method to enhance connector reliability is to move the mating contact area around the final mating spot. In this manner, all the contaminants are not close to the mating. This disclosure describes how to use the energy from a system that is being shipped to help move the contacts and, thereby, create the desired wipe.

    By utilizing an array of phononic crystals, system vibration can be tuned to a desired frequency to induce wipe. The basic components of a phononic crystal are illustrated in the figure below:

    To illustrate the utility of the concept, connectors would be mated and shipped to the customer location. The natural frequency of the structure would be such that the resonance would be outside of typical shipping frequencies and protect the contact from wear. Once current is applied to a phononic crystal assembly, the resonance of the connector would be altered to the shipping frequencies and allow the connector to move. Current would be applied via a battery during shipping for a predetermined amount of time to clear the connectors prior to arrival at the customer's site.
