Abstract
A semi-conductor chip tray and associated retainer and method of use. The tray is provided with a plurality of side notches and tabs which are configured to admit and engage a plurality of posts and flanges, respectively, which extend from the retainer. The tray and retainer are attached to each other by setting the retainer on top of the tray in a linearly offset manner wherein the posts of the retainer extend into the corresponding side notches of the tray. The retainer is then aligned with the tray in a relative sliding motion. During alignment, the flanges of the retainer engage the tabs of the tray to secure the retainer to the tray. The tabs of the tray are provided with recesses which are configured to snugly receive projections which extend from the flanges of the retainer, thus allowing the retainer to be locked in a predetermined position as the retainer and lid are aligned. This locking feature facilitates alignment and prevents inadvertent or accidental displacement between the retainer and the tray.
