Printed Circuit Boards (PCB) in most electronic applications are secured to the package chassis with some type of card-guide device. A typical card guide in commercial electronics is the "locking retainer" type. The evaluation of the structural edge conditions provided by this card-guide type is the topic of this thesis. In particular, an evaluation of the EG&G Birtcher Series 24 LOK-TAINER® is conducted to determine these characteristics. Finite Element Methods (FEM) are applied to the card-guide structure to determine its translational and torsional spring characteristics. Additional FEM analysis of various PCB and card-guide combinations are performed using the spring characteristics determined above and compared to test frequency measurements of these same combinations. Finally, the FEM and experimental results are compared to FEM results of similar PCBs, but modelled with the commonly assumed simply-supported and fixed-edge conditions.
