Abstract: A camera module having an inner wall installed and a method for forming the camera module are disclosed. The camera module includes a lens; a sensor component for sensing light gathered by the lens; and a fixing module, for fixing the lens. The fixing module includes an inner wall that is installed on the sensing component. The inner wall of the fixing module protects a sensing region of an image sensor from unwanted matter resulting from manufacturing or from the outside environment.

Abstract: 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.

Abstract: 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.
