In the multilayer printed wiring board shown in FIG.
When it becomes necessary to connect the power supply patterns 2 and 4, in the multilayer printed wiring board shown in FIG. By providing peer holes 7 for connecting the power supply pattern 6 and the power supply patterns 2 and 4, respectively, the power supply patterns 2 and 4 can be easily connected. Conventional multilayer printed wiring boards often use one layer for the GND pattern and wire various power supply patterns on the other layer, so depending on the placement of electronic components, it may be difficult to route the power supply patterns. Sometimes. Particularly when there are many types of power sources, the above-mentioned problems are likely to occur.

In addition, even with conventional printed wiring boards, the same thing can be done by using a through hole instead of the peer hole 7 shown in Figure 1, but it is possible to do the same thing by using a through hole in the component mounting area and for wiring. Since through-holes other than through-holes must be used, the location and number of holes are extremely limited, and they cannot be freely provided. Further, it is also conceivable that the provision of this through hole may deteriorate the wiring accommodation.

Although the embodiment shown in FIG. 1 shows a simple example, the same concept can be used to supply power even to quite complicated power pin arrangement and electronic component arrangement. The present invention makes it possible to shorten the distance from the power supply source to the power supply pin of an electronic component (which caused AC and DC problems) and improve the electrical characteristics.
