<P>PROBLEM TO BE SOLVED: To join even various joining materials such as gold plating and copper having high laser reflectivity in high speed, high quality, and high stability with a simple structure. <P>SOLUTION: Two members are joined by laser irradiation using a pressurizing tool 2 heated by absorbing a laser beam 1 while squashing one member, which enables thermal diffusion joining in a condition that a junction area is expanded. Therefore, the various joining materials such as gold plating and copper having high laser reflectivity can be joined in high speed, high quality, and high stability with the simple structure. <P>COPYRIGHT: (C)2012,JPO&INPIT |
