ABSTRACT:
Compressed air is blown into a pool of molten solder during soldering to form air bubbles which rapidly rise in the molten solder toward the top. The rising air bubbles strike against a printed circuit board and electric and or electronic components temporarily fixed thereto to achieve soldering. After soldering, inert gas is introduced into the molten solder instead of the air.
