本発明は、電子計算機等の電子装置に用いられる多層配
線基板に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a multilayer wiring board used in electronic devices such as computers.

になる。Multilayer wiring boards include those made by laminating copper-clad boards based on glass epoxy or polyimide, and ceramic multilayer wiring boards made by printing patterns on green sheets (unsintered ceramic), laminating them, and sintering them. be. Regardless of the multilayer wiring board, as the component mounting density becomes high, it becomes extremely difficult to change the wiring using discrete wiring.

あった。To deal with this problem, a ceramic multilayer wiring board was developed in which a floating signal line that does not connect to the pad for mounting components was provided on the inner layer, and this was brought out to the surface layer on the component mounting side (front side) through a through hole. It is proposed in No. 6838. This multilayer wiring board is considerably easier to change wiring than conventional multilayer wiring boards. However, the floating signal line is only drawn out to one side of the board, that is, the front surface layer, so if the wiring changes are concentrated in a localized area, the floating signal line cannot be used effectively, making it difficult to change the wiring. Something happened. Furthermore, when components are mounted on both the front and back sides, the floating signal line cannot be used to change the wiring for components mounted on the back side, making it extremely difficult to change the wiring.
本発明の目的は、上記従来の多層配線基板よりも配線変
更を容易かつ自由に行い得るようにした多層配線基板を
提供することにある。An object of the present invention is to provide a multilayer wiring board that allows wiring to be changed more easily and freely than the conventional multilayer wiring board described above.

１７、上記の目的を達成しようとするものである。The present invention aims to achieve the above object by drawing out the floating signal line through a through hole in both the front and back surface layers so that the floating signal line can be used for wiring changes from either the front or back side. It is something to do.
本発明の一実施例について、第１図および第２図により

であり、第１図は部分断面図、第２図は部品実装面（表
側表面層）を示す部分平面図である。An embodiment of the present invention will be described with reference to FIGS. 1 and 2. The multilayer wiring board of this embodiment is for single-sided mounting, and FIG. 1 is a partial sectional view, and FIG. 2 is a partial plan view showing the component mounting surface (front surface layer).

表側の表面層（部品実装面）には部品１を取り付けるた

は対応する補修用パッド３と接続される。A component attachment pad 2 for attaching a component 1 is provided on the front surface layer (component mounting surface) as shown in the figure, and this is connected to a corresponding repair pad 3.

いる。Reference numeral 8 denotes a floating signal line provided on the inner layer (signal layer), and none of the component attachments is connected to the pad 2. Each floating signal line 8 is drawn out to the front and back surface layers by a through hole 7 and connected to a repair pad 6. In this embodiment, at least a portion of the floating signal line 8 is drawn out through a through hole 7 on both sides of a specific component mounting area.
第１図、第２図で浮き信号ライン８は内層に設けられて
いるが、スペースが許せば、表又は裏の表面層に設けて

側の表面層に引き出される。Although the floating signal line 8 is provided on the inner layer in FIGS. 1 and 2, it may be provided on the front or back surface layer if space permits. Of course, in this case as well, it is drawn out to the front and back surface layers by the through holes.

作業も容易になる。If it becomes necessary to change the wiring of a certain lead of a certain part 1, the part to which that lead is connected must be mounted on pad 2.
The connection line between the through hole 4 and the through hole 4 is cut by peeling it off with a knife or by cutting it with a laser between the through hole 4 and the repair pad 3. Then, the repair pad 3 and the repair pad 6 connected to an appropriate floating signal line 8 are wired and connected. By performing such work, wiring can be easily changed using the floating signal line 8. Moreover, since the floating signal line 8 is drawn out on both the front and back sides, the wiring work described above can be performed on either the front side or the back side, and by concentrating the wiring, a part of the floating signal line 8 can be used effectively. Most situations where this is not possible can be avoided, i.e.,
The degree of freedom in changing wiring is significantly improved compared to the conventional method, and the work is also easier.

号遅延等の面でも有利である。Also, it may be necessary to change the wiring such as wiring across part 1, but if you try to do this with only wiring,
Since the wiring distance becomes long, the use of single wire is not allowed, the number of man-hours for wiring work increases, and it becomes difficult to automate the work using NC equipment. However, in this embodiment, since the floating signal lines 8 are drawn out on both sides of the component mounting area, wiring that straddles the component 1 can be performed using the wiring between the repair pads 3 and 6 and the floating signal lines 8. Since the wiring distance can be sufficiently shortened, it becomes possible to perform wiring efficiently using a single wire, and automation of the wiring work is also easy. This is advantageous in terms of signal delay, etc.

例と同様である。This embodiment is for double-sided mounting, and pads 2 and repair pads 3 for mounting components 1 are provided on both the front and back surface layers. Other than this, this embodiment is the same as the previous embodiment.

It is also clear that the floating signal line 8 can be used to easily change the wiring between the component 1 mounted on the front side and the component 1 mounted on the back side.

Further, the present invention can be applied to any of multilayer wiring boards made of glass epoxy or polyimide as a base material, and multilayer wiring boards made of ceramic as a base material.

This can be done easily and freely, and the floating signal line can be used to easily change the wiring in double-sided mounting, which was extremely difficult in the past, resulting in many effects.
