Since the first clamping portion 32 and the second clamping portion 42 are laterally spaced, the relative positions of the first clamping portion 32 and the second clamping portion 42 are uniform in each solder strip clamping member. For convenience of description, it is agreed in advance: in each set of solder ribbon holders, the first holding portion 32 is located on the left and the second holding portion 42 is located on the right.
