Apparatus for manufacturing semiconductor devices

摘要

Disclosed is a method for fabricating semiconductor devices and apparatus that can be used in the practice thereof. A plurality of sets of lead wires is mounted in a reusable primary lead frame. While supporting the lead frame, and thus the lead wires, a pellet is attached to one wire of each of the sets and appropriate flying leads are bonded in place. The sets of lead wires are then transferred to a reusable segmented lead frame, that includes a plurality of elements which are resiliently mounted with respect to each other. Each element supports one set of lead wires. A plurality of cup-shaped mold cavities defined by the mold are filled with a curable fluid encapsulant. The mold is adapted to cooperate with the segmented lead frame as hereinafter set forth. The ends of the lead wires supporting the pellets are immersed in the encapsulant. Alignment pins on the segmented lead frame made with the alignment openings in the mold, thus insuring proper alignment of the sets of lead wires and the cup-shaped mold cavities.
