A tray-positioning device comprises a driving unit and a positioning unit, wherein the positioning unit provides a plurality of sidewalls that correspond to a plurality of upper sidewalls of a tray. By allowing the driving unit to move the positioning unit toward the tray or vice versa that said individual upper sidewalls are in close contact with the corresponding sidewalls, the tray-positioning device is capable of providing precise positioning for the tray.

An air-suspended die sorter is disclosed, in particular an air-suspended die sorter capable of performing die sorting, die attaching and die pick-up in the semiconductor industry. The present invention provides an air-suspended die sorter capable of eliminating spring preload, and lowering mechanical friction so as to lift die sorting precision and elevate the success rate, and has a cylinder unit, a piston unit and a pressure unit. The piston type design and a precise control of pressure on top and on bottom of the piston, respectively, enables the present invention to offer an air-suspended state that has done away with stress problems associated with the use of springs. The present invention further provides a novel buffer design for reducing friction and die impact often encountered in prior art applications.
