ABSTRACT:
A device loading/unloading apparatus for a device handler is disclosed including a customer tray containing a finished device; a test tray having a plurality of carrier modules, the carrier modules forming a space on its bottom so that the device's bottom is mounted to be exposed downward, the carrier modules having a stop member for supporting the device not to fall freely from the space; bottom loading assembly for picking up the device of the customer tray, moving it under the test tray, and loading it to a bottom space of the carrier module; and stop member spreading assembly installed above the test tray to be conveyable in the same direction as the bottom loading assembly and then spreading the stop member by a predetermined interval when the bottom loading assembly loads/unloads the device on/from the space of the carrier module.
