Abstract
In an electronic apparatus, a busbar assembly is composed of busbars made of at least one previously selected metal material. Each of the busbars has one surface. A solder joint is made of an alloy of previously selected metal materials and placed on the one surface of at least one busbar. The solder joint is changed from a molten state to a solid state to thereby mechanically and electrically connect an electronic component to the one surface of the at least one busbar. The at least one previously selected metal material of the at least one busbar and the previously selected metal materials of the alloy of the solder joint determine that a contact angle of the molten solder joint to the one surface of the at least one busbar is within an angular range of 40 to 60 degrees.
