<p><P>PROBLEM TO BE SOLVED: To perform continuous soldering, by changing a condensed shape of a laser beam suitable for not only one-by-one intermittent soldering, but also spot soldering and flow soldering, and by continuously feeding a solder and applying a laser beam while scanning a workpiece. <P>SOLUTION: The following two condensed shapes of laser beams are changeable to each other: a condensed shape S of a laser beam L to a workpiece 3 formed through a first optical system 6; and a condensed shape S of a laser beam L to a workpiece 3 formed when a second optical system 10 is inserted. By melting a thread solder, which is fed from a thread solder feeding means 2, in the two different condensed shapes S, spot soldering and flow soldering are made switchable to each other in a single device. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
