Abstract:
A gas injection type soldering apparatus, comprising:a gas injection mechanism configured to inject a mixed gas in which a reducing gas is mixed with an inert gas from an injection port to a subject; and a soldering iron configured to perform soldering by heating and melting solder, the soldering iron including the injection port, wherein the gas injection mechanism comprises flow regulators configured to individually regulate flow rates of the reducing gas and the inert gas supplied from gas supply sources separately, a gas mixer configured to uniformly mix the reducing gas and the inert gas supplied from the flow regulators, a gas heater configured to heat the mixed gas supplied from the gas mixer to dehumidify and dry the mixed gas and to increase a temperature of the mixed gas, the injection port configured to inject the heated hot mixed gas, and a controller configured to regulate a mixing ratio of the reducing gas and the inert gas by controlling the respective flow regulators.
