Patent ID: 7311241

Claim:
A method of mounting a terminal on a printed board, the method comprising: preparing a printed board having a terminal hole and a conductor having a first conductor provided on a back side of the printed board and a second conductor provided on a front side of the printed board; inserting a terminal having a first terminal group and a second terminal group into the terminal hole of the printed board from the front and back sides of the printed board; retaining and fitting the terminal into the terminal hole of the printed board, while a soldering portion of the terminal is projected from the terminal hole; assembling the terminal in a state, in which the first terminal group of the terminal is projected from the front side of the printed board and the second terminal group of the terminal is projected from the back side of the printed board; subsequently, arranging the printed board above a solder blowing nozzle of a spot flow soldering apparatus with the first terminal group facing upward; shielding the second terminal group projected toward the solder blowing nozzle with a jig; soldering the soldered portion of the first terminal group to the first conductor provided on the back side of the printed board by solder jetted from the solder blowing nozzle; subsequently turning the printed board upside down to make the second group terminal face upward; shielding the first terminal group facing downward with the jig; and soldering the soldered portion of the second terminal group to the second conductor on the front side of the printed board by solder jetted from the solder blowing nozzle.
