Abstract:
A soldering apparatus for soldering plural soldering points of a workpiece, the plural soldering points being aligned at a predetermined interval, comprising:plural trowel members each having a surface made of a solder repellent material on at least the portion contacting with a solder, said plural trowel members being engaged together to form a solder melting pot and separated from each other to supply the molten solder to one of the plurality of soldering points, a solder tip having a constant volume being supplied to said solder melting pot to be molten and then allowed to drop when said plural trowel members are separated from each other; an additional heating portion which is formed with or adjacent to said trowel members and in close vicinity to said solder melting pot, wherein said additional heating portion simultaneously heats the soldering point to which the molten solder has been already supplied while said solder melting pot is supplying the molten solder to a next soldering point; a workpiece holder for relatively moving the workpiece with respect to said trowel members along an alignment direction of the plural soldering points; and a controller for moving said workpiece holder and controlling said trowel members in synchronism with the relative movement of the workpiece, so that said trowel members are moved up and down and/or opened and closed to supply the molten solder from said solder melting pot to each of the plurality of soldering points of the workpiece.
