Abstract
A mold for manufacturing semiconductor packages, which allows leadframes to be easily separated from a top mold section after a molding process by utilizing eject pins therein. The mold includes a bottom mold section having housing parts on the upper surface so as to allow leadframes to be placed in a flat state therein, and a top mold formed with transports therethrough. The top mold also incorporates runners formed along a lower surface with connections to the transports to introduce encapsulation material into select regions. A plurality of gates and cavities for molding the semiconductor packages are in flow communication. The eject pins are reciprocally mounted in the top mold section contiguous with the runners thereof to facilitate separation of the leadframes from the top mold.
