Abstract
A transport tray for semiconductor devices that includes a retention mechanism. The tray is formed with molded plastic inserts positioned in a tray. Each insert includes a contact surface that is designed to have two stable points, one corresponding to a latched state and one corresponding to an unlatched state. The retention mechanism includes elements that allow the contact surface to rotate and translate relative to the surface of a semiconductor component being inserted or removed from the tray. Rotation across the surface, as opposed to sliding, significantly reduces the wear of the retention mechanism.
