LASER SOLDERING EQUIPMENT

摘要

PURPOSE:To realize a good soldering where production of solder balls is suppressed remarkably by employing a laser soldering equipment in the soldering of non-cleaning type cream solder. CONSTITUTION:In the laser soldering equipment, an inert gas introducing pipe 7 is coupled directly with a transparent case 6 covering a soldering part. Inert gas, e.g. nitrogen gas, is then externally introduced into the transparent case 6 and the soldering part is irradiated with laser beam 10 through the transparent case.
