<P>PROBLEM TO BE SOLVED: To provide a process for manufacturing a lead frame in which a segment block does not project from the upper surface of a resin molding portion, the segment block can be positioned even if it cannot be clamped, and resin burrs are not generated even if the segment block is projecting from the upper surface of the resin molding portion. <P>SOLUTION: A segment block 2 can be positioned at a through hole 3a without generating resin burr by a manufacturing process comprising a step for forming a first resin molding portion 3 having a predetermined through hole 3a in a space surrounded by the distal end of a plurality of lead portions 1a of a metal plate material 1, a step for inserting the segment block 2 into the through hole 3a, and a step for forming a second resin molding portion 4 on the outside of the first resin molding portion 3 of a lead structure formed in the segment block insertion step. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
