Title:
NON-CONTACT TYPE SOLDERING IRON CAPABLE OF INTERMITTENT SOLDERING
Document Type and Number:
WIPO Patent Application WO/1998/030352
Kind Code:
A1
Abstract:
When soldering is carried out by using a soldering iron and by blowing a high temperature gas stream to a to-be-soldered portion of a work, a main heating gas stream having a high temperature sufficient to melt and soften the solder is jetted from the distal end of the soldering iron, and a pre-heating gas stream is generated and jetted from a part of the main heating gas stream by utilizing the back pressure resulting from the temperature rise and expansion of the main heating gas stream in such a manner as to encompass the main heating gas stream. After the pre-heating gas stream is blown to the to-be-soldered portion of the work for pre-heating, the main heating gas stream is blown to the to-be-soldered portion of the work so pre-heated, and soldering is carried out in the atmosphere in which the main heating gas is encompassed by the pre-heating gas stream.
