<p>PROBLEM TO BE SOLVED: To provide a technique capable of reducing a cost for packages by using a common lead frame even when the external shapes of the packages are different. SOLUTION: The technique uses a lead frame 1, including a tab hanging lead part 5a having thin width parts 5a1 and 5a2 . In the case of the first shape, the lead frame is inserted and held, so that the resin introduction holes 9 of mold dies (8a, 8b) correspond to the part 5a1 of the part 5. After firmly sealing resin, the part 5a1 is cut off. In the case of the second shape, the lead frame is inserted and held, so that the resin introduction holes 9 of the mold dies correspond to the part 5a2 of the part 5. After firmly sealing resin, the part 5a2 is cut off. The common lead frame 1 can be used in both of the case of the first shape 254 and the case of the second shape.</p> |
