Method of die bonding semiconductor chip by using removable non-wettable by solder frame

摘要

A method and apparatus for accurately positioning a semiconductor chip onto a die bond pad region of a semiconductor package. A removable non-wettable by solder 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.
