PROBLEM TO BE SOLVED: To align a printed circuit board accurately at the time of inspection and adjustment by making a notch in the end face at the circumferential part of an insulating board and fitting an aligning guide pin freely in the notch as an alignment reference part for inspecting and adjusting the electrical characteristics. SOLUTION: An alignment reference part 2 is provided on the longitudinal end face of a printed circuit board 1, and an aligning guide pin 3 is inserted into the notch at the time of inspection and adjustment thus aligning the printed circuit board. The alignment reference part 2 is required for the printed circuit board 1 at more than one point. In order to enhance the alignment accuracy, the alignment reference parts are spaced apart from each other as much as possible. According to the arrangement, the printed circuit board can be aligned accurately at the time of inspection and adjustment while reducing the size and the cost thereof. |
