<p><P>PROBLEM TO BE SOLVED: To provide a soldering device which improves the precision of soldering. <P>SOLUTION: The soldering device 100 includes a laser component 102, an optical fiber cable 105, a first lens 104, a second lens 107, a changing member 108, and a control part 101. The laser component 102 emits first laser beam, and the optical fiber cable 105 allows the first laser beam to pass through. The first lens 104 guides the first laser beam emitted from the laser component 102 to the optical fiber cable 105, and the second lens 107 irradiates the soldering part 12 with the second laser beam which is obtained by converging the first laser beam from the optical fiber cable 105. Then the changing member 108 changes the irradiation area of the second laser beam with respect to the soldering part 12. The control part 101 controls the movement of the changing member 108 so that the irradiation area of the second laser beam with respect to the soldering part 12 changes from the first area including the soldering part 12 and the circumference of the soldering part 12 to the second area including only the soldering part 12. By this configuration, the precision of the soldering can be improved. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
