Title:
SOLDERING METHOD AND SOLDERING IRON
Document Type and Number:
WIPO Patent Application WO/1998/030351
Kind Code:
A1
Abstract:
When a soldering iron is used to subject a work to soldering while blowing a high temperature gas flow against that portion of the work, which is to be soldered, a tip end of the soldering iron jets a main heating gas flow of a sufficiently high temperature to melt and soften solder, a preheating gas flow of a temperature, which is lower than that of the main heating gas flow but sufficiently high to preheat the solder, is jetted surrounding the main heating gas flow, the preheating gas flow is blown against that portion of the work, which is to be soldered, to preheat the portion, and then the main heating gas flow is blown against that portion of the work, which is to be soldered and has been preheated, to effect soldering in an atmosphere surrounded by the preheating gas flow.
