Abstract
PURPOSE:To improve the mechanical strength and the level balance of the lead frame, by forming the deformable portions on the connecting part between the lead portion consisting of the tab, lead and dam of the lead frame and the outer frame, the said portion being subject to deformation in the level direction caused by heat stress. CONSTITUTION:The lead portion 11 consisting of the tab 3, lead 5 and dam 6 is connected to the outer frame 2 by the connecting portion consisting of the tab lead 4, dam extention 7 and lateral supporter 8. Each connected portion is incorporated into a single entity. That is to say, the tab 3 is connected to the outer frame 2 by a pair of tab lead 4, and the dam 6 with leads is connected to the outer frame 2 by the dam extensions extended in four directions, and the dam 6 without lead 4 is connected to the outer frame 2 by the lateral supporter 8. In this formation, the easy deformable portion 14 of the crooked shape is formed between the dam 3 and the outer frame 2, where the heat stress in the level direction can be absorbed.
