Abstract: A cantilevered clip is provided for holding a stack of at least one tray and tray cover. Stack compressive forces applied by the clip are substantially limited to tray and cover edge portions. The clip has a channel base with left and right side walls attached for restricting movement of a stack in left and right directions. Pressure members are positioned orthogonal to at least one wall. An aperture is located adjacent to each pressure member and partially extends into each wall. Protrusions above the base extend inward towards the walls of the channel for captivating the stack in an upward direction.

Abstract: A clip is provided for holding a stack of at least one tray and tray cover. Stack compressive forces applied by the clip are substantially limited to tray and cover perimeter rail portions. The clip has a channel base with left and right side retaining walls attached for restricting movement of a stack in left and right directions. Left and right rods protrusions above the base extend inward towards the walls of the channel from the left and right side walls respectively for captivating the stack in an upward direction. Spring protrusions extend upward from the base on input and output ends of the channel, and are configured for applying an upward spring force on opposing bottom edge areas of the stack.

Abstract: A wafer container comprising a base and a cover that nest together. The base includes a staggered wall structure composed of inner and outer walls. The staggered wall structure is arranged so that forces from side impacts are absorbed principally by outer wall segments. A rib on the cover restrains the outer wall segments from flexing beyond the inner wall diameter. Reference tabs on the base facilitate alignment of the base to the cover.

Abstract: A tray for storing and handling delicate components is strengthened with a reinforcement bar. Reinforcement bars are arranged in parallel to enhance resistance against cracking and warpage of the tray. Each reinforcement bar may include a support structure. A radius on all or a portion of tray members having a sharp edge may serve to strengthen the tray further. Tray members including ribs, openings, indentations, and pockets can have all or part of their sharp edges covered with a radius.
