Abstract
A method for producing an electronic circuit device includes a repair step in which, in a case where a semiconductor device once mounted on a wiring board is defective, the defective semiconductor device is removed from the wiring board and a new semiconductor device is mounted on the wiring board. The repair step includes the steps of: removing an excessive residue of a brazing metal residue remaining on lands of the wiring board from which the defective semiconductor device has been removed and leaving a uniform amount of the brazing metal residue on the lands; aligning the new semiconductor device with the wiring board; and melting the brazing metal residue which is made uniform and remains on the lands and projecting electrodes of the new semiconductor device by heating, thereby connecting the new semiconductor device to the wiring board.
