Abstract:
1. An electronic apparatus comprising: an electronic component; a busbar assembly composed of a plurality of busbars made of at least one previously selected metal material, each of the plurality of busbars having one surface, the plurality of busbars being arranged to be assembled so as to constitute a predetermined circuit pattern; and a solder joint made of an alloy of previously selected metal materials and placed on the one surface of at least one of the plurality of busbars, the solder joint being changed from a molten state to a solid state to thereby mechanically and electrically connect the electronic component to the one surface of the at least one of the plurality of busbars, the at least one previously selected metal material of the at least one of the plurality of busbars and the previously selected metal materials of the alloy of the solder joint determining that a contact angle of the solder joint in the molten state with respect to the one surface of the at least one of the plurality of busbars is within an angular range of 40 to 60 degrees.
