GANG FLIPPING FOR FLIP-CHIP PACKAGING

摘要

An improved method and apparatus for packaging integrated circuits are described. More particularly, a method and apparatus for use in securing a plurality of integrated circuit dice to a lead frame panel are described. Each integrated circuit die includes an active surface having a multiplicity of solder bumps. The lead frame panel includes an array of device areas, each including a plurality of leads. The method includes positioning a plurality of dice into designated positions on a carrier such that the active surfaces of the dice are facing upwards. The carrier includes a carrier frame including an associated array of carrier device areas. A lead frame panel may be positioned over the carrier such that the solder bumps on the active surfaces of the dice are adjacent and in contact with the associated leads of the associated device areas.
