Description
【発明の詳細な説明】 本発明は印刷配線板に関するものである。[Detailed description of the invention] The present invention relates to printed wiring boards.
従来、印刷配線・臂ターンが、ランド間１本配線の印刷
配線板においては、印刷配−・平ターンが。Conventionally, in printed wiring boards with one wiring between lands, the printed wiring/arm turn is printed wiring/flat turn.

The wiring was carried out by adding additional fabrics such as m, or by reducing the line width of the printed wiring pattern to a level that allowed two wirings between the lands. This has led to an increase in costs due to an increase in man-hours and a decrease in yield.

提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a printed wiring board that eliminates the drawbacks of the prior art described above and can increase the accommodation rate of printed wiring patterns at low cost.

するものである。The present invention enables two-way mk only for printed wiring patterns in areas that cannot be accommodated with one land-to-land wiring, and there is no functional problem even if the land on the component mounting surface side is removed. Have you selected a through hole that does not appear to have any land, deleted the land on the component mounting surface of that through hole, and accommodated two printed wiring patterns between the landless through hole and the land, or between the landless through holes? This is a characteristic feature.
以下、本発明を図面に従って説明する。The present invention will be explained below with reference to the drawings.

ランド１間に２本の配線は不可能である。Figure 1 shows the conventional printed wiring between land 1 and 9 terminals 2i1.
A cross-sectional view of the printed wiring board 3 in the case of this distribution is shown.
- If the distance 1!14 between the nine terminals cannot be made any smaller, it is impossible to provide two wires between the lands 1 unless the solution width of the printed wiring pattern 2 is made significantly narrower.

配線した印刷配線板３の断面図を示す。FIG. 2 shows an embodiment of the present invention, and for a through hole 6 which does not cause any functional problem even if there is no land on the component mounting surface 5 side, the side of the component surface of the through hole is deleted. This is a sectional view of a printed wiring board 3 in which two printed wires 9 turns 2 are wired between adjacent lands 1.

きる。According to the present invention, since the printed wiring pattern cannot be accommodated completely, there is no need to conduct additional wiring after components are mounted on the printed wiring board, and the line width of the printed wiring/guitar can be reduced to the level of one wiring between lands. The thick and narrow width enables two-way mt between lands, and can be expected to have effects such as increasing the accommodation rate of printed wiring patterns at low cost.
