（産業上の利用分野）
この発明は、電極により熱圧接して接合する際
に被接合材を保持する熱圧接用治具に関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a jig for thermo-pressure welding that holds materials to be joined during thermo-pressure welding using electrodes.
（従来の技術）

とが可能である。(Prior art) A joining method is known in which the joining parts of materials to be joined are joined by thermo-pressure welding using electrodes. According to this joining method, the electrode itself generates resistance heat, so copper, copper, etc. are used as the materials to be joined. Even materials with excellent electrical conductivity such as copper alloys, which are considered unsuitable for resistance welding due to resistance heating of the materials to be joined, can be joined without any problems.

させる。 When joining, the joining part of the materials to be joined is held between the left and right holding members of the thermocompression welding jig, which are arranged perpendicularly to the upper and lower pair of electrodes, and in this state, for example, the upper electrode is placed on the joining part. The electrodes are lowered and brought into pressure contact, and current is passed between the upper and lower electrodes to generate heat resistance in the electrodes themselves.

うことができず、信頼性の点で問題があつた。 However, the iron holding member has a problem in that the surface of the holding member rusts after long-term use.
In addition, because it is conductive, part of the current that should flow to the electrode is diverted to the holding member, and because the insulation is poor, part of the heat that is transferred from the electrode to the joint part is dissipated. As a result, good bonding could not be achieved and there was a problem in terms of reliability.

圧接用治具を提供することである。 This invention was made to solve the problems of the prior art described above, and its purpose is to:
It does not rust, part of the current that should flow to the electrodes is shunted, and part of the heat that should be transferred to the joint part does not dissipate, making it possible to perform a good bond and increase the reliability of the bond. An object of the present invention is to provide a jig for thermo-pressure welding that can improve the performance.

As a result, the joint parts are pressurized and heated by the electrodes to join them. At this time, since the holding member is made of ceramic and has insulating and heat-insulating properties, part of the current flowing through the electrodes is transferred to the holding member. Also, there is no possibility that part of the heat transferred from the electrodes to the joint will be dissipated.
