PURPOSE:To fit a multi-terminal to both faces of a substrate and fix it by reflowing by changing bending positions in turn to obtain a zigzag lattice comb-shaped multi- terminal at the time of bending the comb-shaped multi-terminal in a stairway shape. CONSTITUTION:A comb-shaped multi-terminal is obtained by continuously punching and bending a metal plate, bending positions are changed in turn to form terminals 12 and 13 when they are bent in a stairway shape. One end of each of the terminals 12 and 13 is connected by a chain section 11. Soldering sections 18 to be fixed to the terminal pad of a substrate are formed on the opposite end of the chain section 11. The terminal 12 is straightly extended from the chain section 11 to form the required terminal length, then the first bending 14 and the second bending 15 are performed to form the soldering section 18 at the tip. The step difference between the first bending i4 and the second bending 15 becomes the row direction through hole pitch of a mother board. The first bending 16 and the second bending 17 are performed on the terminal 13 immediately from the chain section 11, the soldering section 18 is provided after the required terminal length is formed nearly in parallel with the chain section 11. |
