ABSTRACT:
A method and apparatus for accurately positioning a semiconductor chip onto a die bond pad region of a semiconductor package. A frame is constructed for slidable contact with peripheral walls of a semiconductor package die cavity. A frame central aperture with a wide upper opening and a narrower lower opening guides a semiconductor chip dropped therethrough into a precise position in the die cavity.
