PURPOSE:To speed up the tempo of a line bonding operation by making the entire practical width of the tip part of an inner lead the same and as wide as possible. CONSTITUTION:The bonded parts 17a-17c of inner leads 14a-14c have a fixed interval x between each other along a tab side, and have practical surfaces ya-yc which are all equal at the bonded parts 17a-17c and increasingly enlarged. In this way, if the variable allowable width of a capillary or a wedge of an automatic bonder is increased in the direction of bonded wiring between the electrode 18 of a pellet 13 and bonded part of the inner lead, it is possible to speed up the tempo of a bonding operation. |
