ース化ためにバスバーが使用されている。2. Description of the Related Art Conventionally, a wiring board using a bus bar has a circuit board wiring through which a large current flows from the viewpoint of improving connection reliability.
In addition, it is used as wiring for achieving space saving by eliminating the need for a wire harness or the like. For example, in a large-scale computer requiring a large current supply, such as a power supply mechanism disclosed in Japanese Patent Application Laid-Open No. 63-182897,
A bus bar is used to increase an allowable current value, reduce a voltage drop, and improve heat dissipation. Also, JP-A-8-26
As in the electronic control unit disclosed in Japanese Patent No. 8254, with the progress of electronic control of automobile parts, bus bars are used to reduce the installation space by integrating the wiring parts of the automobile control parts into a module. .

の方法で接続される。[0003] The bus bar has a conductor portion made of a copper-based material and an insulating portion made of an organic film such as polyimide, and is formed by bonding an organic film from both sides with a wiring pattern formed on the conductor portion. Since the conductor itself can be easily deformed, a three-dimensional three-dimensional wiring can be easily formed. For this reason, there is an advantage that a design according to the space for installing the wiring can be performed. The bus bar and the mounted components are connected by a method such as wire bonding, welding, caulking, or a connector according to the required specifications of the connection portion.

あるいは配線ピッチの縮小を要求される。By the way, as the number of mounted electronic control parts increases, the number of connection portions formed on the bus bar also increases. On the other hand, since the area in which the bus bar wiring can be formed at one time is also limited, the wiring width or the wiring pitch of the bus bar must be reduced. Further, as the modularization of the wiring board, the electronic components, and the control board progresses, it is required to reduce the wiring width or the wiring pitch in order to realize the space saving of the module installation part.

コスト高になる欠点がある。[0005] Due to an increase in the value of current flowing inside the bus bar due to an increase in the number of control parts connected to the bus bar, and an increase in current density due to a reduction in the size of the bus bar connection portion, connection of the bus bar connection portion such as improvement in heat resistance has been made. Maintenance or improvement of reliability is required. In order to ensure connection reliability, it is necessary to select a method that can obtain a stronger connection strength and connect. Soldering and wire bonding have low connection strength, and in the case of connector connection, reliability can be ensured only when the combination of the specified male and female terminals is used, but when connecting with the bus bar, the reliability decreases. There are drawbacks that cannot be used. For this reason, the connection has to use a method involving permanent deformation such as welding or caulking. On the other hand, if a part connected to the bus bar breaks down and needs to be replaced, or if a connection failure occurs due to permanent deformation such as welding, the defective connection is repaired and the module is regenerated. There is a disadvantage that there is no means to do so. For this reason, defective products must be discarded. In particular, when the number of mounted components is large or when there are expensive components, the module has a disadvantage that the cost is increased.
