Abstract
This disclosure addresses the challenge of aligning multiple PCBs—such as a backplane and multiple switch cards—with a single Field Replaceable Unit (FRU) during installation. Traditionally, fixed mounting of all PCBs can cause misalignment and introduce harmful shear forces on connector pins, leading to deformation, signal degradation, or permanent damage. By fixing the backplane and allowing the FRU to self-align within its rail-mounted tolerances, the system ensures proper initial positioning. Additionally, each switch card is mounted on elastic neoprene grommets, enabling the card to “float” and adjust its position in any direction. This innovative approach accommodates manufacturing tolerances, reduces stress on connectors, preserves signal integrity, and enhances overall reliability in complex, multi-board assemblies.
