Lead frame with lead-securing tape bonded to the inner lead sections of plural leads and a method of manufacturing the same

摘要

A lead frame comprises an island supported by island supports at its four corners and leads extending from its frame section to the island. The leads are composed of inner leads and outer leads which are connected to each other with dam bars. Plating layers are formed on the surfaces of the tip sections of the inner leads, and lead-fixing tape is bonded to the distal portions of the inner leads with an adhesive which acquires elastic properties when set. The lead-fixing tape is bonded with its inner side located 0.1 mm-2 mm inward from the tips of the inner leads.
