PURPOSE:To obtain a lead frame for a test without being thrown away after one time use only, adhered resin can be removed simply, and enabled to be used repeatedly by a method wherein a dummy lead frame formed with no lead patterns is used. CONSTITUTION:Feeding referential holes 9 for positioning, resin penetrating openings 10 to make resin as to extend over both of upper and lower metal molds, and openings 11 for regulation of adhesion intensity of the upper and lower metal molds are provided to a lead frame 42, and the surface thereof is formed in the flat condition. Accordingly, after resin shot for a test is performed, adhered resin can be removed easily, and the lead frame thereof can be used repeatedly for the plural number of times without one time use only and then thrown away. The dummy lead frame thereof can be used repeatedly for 20 times usually, and the amount of the lead frames used can be reduced to 1/20 or less as compared with the usual case. |
