PURPOSE:To eliminate the variation in supply and to supply linear solder in conformity with various conditions in a laser soldering metod, by detecting the supply position of the linear solder with high accuracy. CONSTITUTION:Linear solder 1 is supplied at a correct rate at a velocity V1 from the start position up to L1, and is returned at the stepwise velocities V2, V3 quickly at a specified length (from the position of a sensor 4 up to the position behind the same). The V2 is the velocity in a range 7 where a laser beam is irradiated, and the V3 is the velocity beyond said range. The solder 1 is then supplied at a velocity V4 up to the sensor position, where the solder is positioned with high accuracy by the sensor 4. The solder is supplied at a velocity V5 from said position up to L5. Thereafter, the solder is kept standing by in said position and the next cycle is started. |
