发明名称 Lead frame design for chip scale package
摘要 A universal lead frame for mounting dice to form integrated circuit packages is provided. The lead frame may be made from a metal sheet, which may be stamped or etched. The lead frame provides a plurality of posts and a connecting sheet connecting the plurality of posts. Dice are adhesively mounted on to a first set of the plurality of posts. The dice are then electrically connected to a second set of the plurality of posts using wire bonding. An encapsulating material is placed over the dice and lead frame, with the connecting sheet keeping the encapsulating material on one side of the lead frame. The connecting sheet is then removed, leaving the posts as separate leads. The integrated circuits formed by the encapsulated dice and leads may be tested as a panel, before the integrated circuits are singulated.
