- the punching hole lb is configured so that the force on the extension line of one side lc on the main body substrate 10 side of the two long sides lc and Id facing the slit 1 does not protrude toward the main body substrate 10 side.
- the punching hole 2b is configured so that the force on the extension line of one side 2c on the main body substrate 10 side of the two long sides 2c and 2d opposed to the slit 2 does not protrude toward the main body substrate 10 side.
- FIG. 16 is a front view showing the collective substrate of the present embodiment.
- the remaining portion 8 is provided at the apex portion of the main body substrate 10, and the first and second slits 3 and 4 sandwich the apex portion of the main substrate 10.
- the punching holes 3 a and 4 a are provided on the two sides, respectively, and are provided at the front end portions of the first and second slits 3 and 4 on the remaining portion 8 side.
- two perforation holes 7 are drilled in the remaining portion 8 remaining between the insertion hole 3a and the insertion hole 4a.
- Other configurations are the same as those in the fourth embodiment. In the collective substrate having such a configuration, in addition to the effect of the fourth embodiment, the effect of the fifth embodiment can be obtained.
- FIG. 17 is a front view showing the collective substrate of the present embodiment.
- the collective substrate 52 of the present embodiment does not have a discarded substrate as compared with that of the first embodiment.
- the first and second slits 1 and 2 are provided between the two adjacent main body boards 10 and 10, and the first slit 1
- An insertion / extraction hole la is provided at the tip.
- the two main boards 10 and 10 constitute a first board and a second board.
- the collective substrate 52 of the present embodiment has a discarded substrate. Therefore, in the electronic component mounting process, the clamped portions 13 provided at the four corners of the main substrate 10 are clamped. The electronic parts are mounted on the mounting surface in this state.
- slits 1 and 2 are formed only between two adjacent main body substrates 10 and 10.
- the electronic component mounting process as described above, the electronic component is mounted in a state where the held portion 13 is pressed by a clamp tool or the like.
- the remaining part 8 is cut by the router processing machine in the same manner as in the first embodiment, and the two adjacent main body boards 10 and 10 are divided.
- the collective board As described above, in the collective board according to the present invention, electronic components are mounted on the board at a high density in order to reduce the size of the apparatus, and a discarded board is provided around the main board in advance to provide an electronic component.
- a discarded board is provided around the main board in advance to provide an electronic component.
