Abstract:
1. A soldering apparatus comprising: a conveyance path through which an electronic circuit board is conveyed; a fluxer which applies a flux having water as a solvent to a surface of the electronic circuit board to be soldered; a first heating device which heats the electronic circuit board; a water removal device which removes water attached to the electronic circuit board after processing in the first heating device; a second heating device which heats the electronic circuit board to maintain the electronic circuit board at a temperature at which the flux exerts its activating action; a flow solder bath which attaches molten solder to the electronic circuit board; and a cooler which cools the electronic circuit board, wherein the fluxer, the first heating device, the water removal device, the second heating device, the flow solder bath and the cooler are successively disposed along the conveyance path, wherein the water removal device has a gas blowing portion from which a gas is blown to an electronic component disposition surface of the electronic circuit board on which electronic component parts are disposed, and a drawing portion through which water is drawn from the surface to be soldered, wherein the gas blowing portion has a first jig in the form of a lid, which is to surround one or more of the electronic component parts disposed on the electronic component disposition surface, and wherein the drawing portion has a second jig in the form of a tray, which is to surround portions of the one or more electronic component parts surrounded by the first jig, the portions being on the surface to be soldered.
