This application relates to methods and apparatus pertaining to a SIM tray that includes a deformable portion. When the SIM tray is subjected to stresses that result from tolerance stacking, the deformable portion accommodates the differences tolerance errors by allowing the non-deformable portion of the SIM tray to move substantially independently from one another. Creating the deformable portion can be accomplished by utilizing materials with lower relative moduli of elasticity, dovetails, magnets, or other means.
