PURPOSE: To avoid overheat through short-time irradiation of a high laser output by requiring an optimizing of the Z-adjustment of a laser optical system or the like and making a laser output controllable against soldering, for the purpose of performing laser soldering even on a circuit mounted with a number of components. CONSTITUTION: An equipment is employed which is provided with a temperature/ time controller, its operating part and a temperature gradient controller and which uses CW-Nd:YAG laser. In the laser head 10 of a first multi-axes robot 11 a laser output controllers 12, 13, 16 of a laser spot, face to be irradiated and soldering point are installed. A solder wire feeding device 13, which is additionally computer-controlled, is incorporated in this head 10 and its processing controllers. A second multi-axes robot 111, which is installed in addition to the first robot 11, is equipped with a device for a charging part 31, standby soldering part 32 and flux 33. Then, by using a 3-6 axes positioning device for a laser soldering process, the laser output can be controlled, and the overheat can be avoided. |
