<p>PROBLEM TO BE SOLVED: To provide a soldering method capable of achieving excellent soldering between a pad and a conductive wire.SOLUTION: Disclosed is a soldering method in which, after attaching an amount of solder 11 satisfying the formula (1) below to a pad 3 in advance, a conductive wire 21 is soldered to the pad 3 by melting solder 12. However, in the formula (1), A is a diameter of the conductive wire 21, B is a length of the conductive wire 21 in the extension direction on the pad 3, C is a length of the pad 3 along the extension direction of the conductive wire 21, D is a width of the pad 3, X is an amount of solder 13, andπis a circle ratio.</p> |
