PURPOSE:To amount a pair of terminal boards oppositely to each other at an exact spacing between the same in the stage of providing said terminal board by attaching a supporting fitting connecting the terminal board by means of a connecting piece on a circuit board then impressing a voltage between the terminal boards to cut the connecting piece by fusion. CONSTITUTION:When a switch is thrown, an air cylinder operates and 3 sets of electrode means descend toward the respective supporting boards 1 provided on a chip board 7. Solenoid valves of a water feed means are opened for a specified time to drop water to the centerl part of the connecting piece 4 of a supporting fitting 1. The probes 10a, 10b of the respective electrode means 10 are pressed to the flat part of the terminal boards 2, 3 of the fitting 1 and a voltage is impressed thereto from a power transformer, by which the central part of the piece 4 is instantaneously cut by fusion. |
