Abstract
A logic card frame for housing removable printed circuit boards comprises a pair of identical one piece molded half frames that are snapped together, stackable, and slideable from an inserted to a withdrawn position within an associated rack or cabinet. The assembled half frames include integrally molded circuit board guide tracks, each with a groove, a flexure, and a raised portion to guide and prevent vibration of a printed electrical circuit board inserted into a guide track. The base on which the logic card frame is slideably mounted has a ratcheted latch and leaf spring combination for retaining the inserted logic card frame.
