PURPOSE: To straighten a pin with a high accuracy by inserting a straightening tool on which thin plates have been provided in parallel, into electronic parts having many pins in a shape of parallel crosses, and bringing the parts and the thin plates to a relative movement minutely in two vertical directions.
CONSTITUTION: As for a straightening tool 1, many thin plates 2 are provided in parallel, and it is provided so that it can move upward and downward through a slider mechanism 6. Also, electronic parts 3 on which many terminal pins have been arranged in a shape of parallel crosses are attached to a rotary table 10 on an X-Y table 11. In this constitution, the tool is inserted between the pins of the parts 3, and thereafter, the pin is straightened by moving minutely the pin in the vertical direction of the thin plate 2. Subsequently, the parts 3 are rotated by 90°, and the pin is straightened by executing its minute movement in the same way. Therefore, the pins which have been massedly provided can be straightened with a high position accuracy, and the packaging density of a circuit board can be improved.
