Description of the Related Art For example, as shown in FIG. 5, a printed wiring board 9 has a circuit forming portion 92 at a central portion of an insulating substrate 91, and has a number of elongated holes 8 at a peripheral portion. The slot 8 is provided for positioning the printed wiring board 9 at a predetermined reference position when a through-hole is formed in the printed wiring board 9 or when many circuit forming steps are performed.

る。[0003] Therefore, it is necessary to provide the long hole 8 such that its size and its longitudinal axis are in a normal state. The oblong hole 8 is used to avoid stress and distortion when the printed wiring board 9 expands and contracts due to heat when the printed wiring board 9 is subjected to processing such as molding and soldering. It is drilled in a shape.

７号）。[0004] Conventionally, the long hole is formed by step processing using a drill or router processing. As shown in FIG. 6 (A), the step processing by the above-mentioned drill is performed in a longitudinal direction along the axis 85 (FIG. 5).
In this method, several drills are drilled. In this method, the center of the drill is moved in units of several to several tens of micrometers, and the drill is made in several steps.
An oval or circular continuous hole is formed (JP-A-4-35248)
No. 7).

る。However, in the stepping method using a drill, as shown in FIG. 6 (B), the first circular hole 81 can be formed normally, but after the second round, it is insulated from the rotating drill 99. The contact with the substrate causes the insulating substrate to move in the direction of the arrow 911 opposite to the drill rotation direction 990.
Escape in the direction of. Therefore, as shown in FIG. 6C, the axis 821 of the completed elongated hole 82 is in a different direction from the axis 85 of the elongated hole 8 to be obtained (FIGS. 5 and 6A). There is a problem that a long hole is not formed. Further, since the hole to be drilled at the center of the elongated hole escapes in the direction of the left and right pre-drilled holes, there is a problem that the center does not have a regular diameter 2R.

る。On the other hand, in the case of the router processing, since the hole is used as a reference hole and the hole is processed again, there is a problem that the positional accuracy with the circuit forming portion is deteriorated. In any of the above cases, the inner wall of the elongated hole is likely to have irregularities because the hole is drilled by the movement of the drill and the movement of the router. Therefore, when the printed wiring board expands and contracts due to heat during various processes by inserting the elongated hole of the printed wiring board into the positioning pin, the sliding between the inner wall of the elongated hole and the positioning pin is performed smoothly. There is a problem that is not.
