ABSTRACT:
A multi-stacker for a handler is provided. After a device positioned in a test tray is tested at a test site and is classified, each test tray is unloaded according to the classification. The multi-stacker for a handler includes a stacker frame installed longitudinally on a handler frame and coupled to a side plate, a tray stacking portion for stacking a test tray loaded with a classified device in the stacker frame, and a guide for determining a position of a test tray placed on the tray plate and installed at four edges of the tray plates so as to prevent the tray plate from deviating from a predetermined position. As the tray is moved up and down along an inside of the guide, the test tray holding a classified device may be unloaded.
