ABSTRACT:
A stiffening device for an electronic assembly which engages each circuit card assembly (CCA) in approximately its center of area. Each CCA which is positioned within an electronic enclosure has a collar which surrounds a hole through its center of area. A shaft is passed through the electronic enclosure and pins engage each of the collars. The shaft and pin assembly rigidly connects each of the CCA's to the body of the electronic enclosure. This has the effect of reducing the vibrational deflection and potential damage to each CCA, allowing the electronic enclosure to survive a much higher vibrational and shock environment.
