Abstract:
A solder-bonding structure comprising:a terminal having a generally planar section; and a generally planar circuit board having an elongated hole for receiving said generally planar section of said terminal, said elongated hole penetrating through said circuit board and having a longitudinal axis that extends in a first direction that is generally parallel to said generally planar circuit board and said elongated hole comprises two conductors arranged around opposed open ends of said elongated hole, respectively; wherein: said generally planar section of said terminal is arranged to be inserted through said elongated hole of said circuit board and to be solder-bonded to said two conductors, wherein said generally planar section of said terminal includes at least one flow-passage defining portion that defines at least one flow passage for permitting flow of melted solder material therethrough in a second direction perpendicular to a plane of said generally planar section of said terminal and also in a third direction generally perpendicular to the plane of said generally planar circuit board; said flow-passage defining portion of said terminal includes: at least one embossed portion that is formed by embossing said generally planar section of said terminal in said second direction to provide at least one embossed recess on one of opposed sides of said generally planar section of said terminal, wherein said at least one embossed recess provides communication between said opposed open ends of said elongated hole when said generally planar section of said terminal is inserted to a predetermined position in said elongated hole; and a through hole penetrating through said generally planar section of said terminal, wherein said through hole extends over at least one of said opposed open ends of said elongated hole in said third direction when said generally planar section of said terminal is inserted to said predetermined position in said elongated hole; and said at least one embossed portion includes a plurality of embossed portions, wherein said plurality of embossed portions are spaced from each other in said first direction and are embossed in a common direction.
