一种用以替代融合结构引线框的引线框
摘要：
一种用以替代融合结构引线框的引线框，属于半导体封装技术领域。该发明的引线框通过多个第二内引脚之间相互电性连接为一体并通过小岛连筋与所述小岛电性连通，可以使第二内引脚能替代融合结构引线框的融合内引脚，同时可以使该引线框的引脚以小岛的对称分布，加工相对容易，成品率高。并且，该引线框的小岛面积可以根据所封装的电路芯片的面积灵活设计，不存在小岛边与引线框边之间的间距不足的问题，因此，该引线框还具有通用性强的优点。
摘要（英）：

The invention discloses a lead frame for replacing a lead frame of a fusion structure, belonging to the technical field of semiconductor package. According to the lead frame disclosed by the invention, a plurality of second inner pins are mutually and electrically connected into a whole and is electrically communicated with an island through island connecting ribs so that the second inner pins can replace fusion inner pins of the lead frame of the fusion structure; and the pins of the lead frame can be distributed symmetrically about the island; thus the processing is easy; and the yield is high. The area of the island of the lead frame can be flexibly designed according to the area of a packed circuit chip without the problem of insufficient distance between the edge of the island and the edge of the lead frame, so the lead frame also has the advantage of strong generality.
