When a printed board is soldered by a dipping method, a great deal of dross is generated on a jet solder tank. The dross is a mixture of melted solder and oxide. A worker takes out the dross from the jet solder tank, and throws it away. Thus, a large amount of the solder is consumed. The present invention relates to a separating device for separating oxide and solder from dross. A container (21) is provided with a heater (22). A cover (24) is set over the container (21) to be freely attachable or detachable, and further a non-oxidizing gas supplying opening (28) is made in the cover (24) or the container (21). A stirring spatula (25) for stirring the surface of a melted solder (23) put into the container (21) is set near the surface of the melted solder (23).
Method for separating oxide from dross, wherein the dross floating on a melted solder in a non-oxidizing atmosphere at 100° C. or higher is mechanically stirred together with the melted solder, thereby separating the solder and the oxide.
A device for separating oxide from dross, wherein a container is provided with a heater, a cover is set over the container to be freely attachable or detachable, a non-oxidizing gas supplying opening is made in the cover or the container, and a stirring spatula for mechanically stirring the surface of a melted solder put into the container is set near the surface of the melted solder.
A jet solder tank comprising a heater for heating a solder and a nozzle for jetting the solder melted by heating, wherein a dross reservoir is covered with a cover, and a stirring spatula for mechanically stirring the surface of the melted solder is set up inside the cover.
A jet solder tank comprising a heater for heating a solder and a nozzle for jetting the solder melted by heating wherein a dross reservoir is covered with a cover, a non-oxidizing gas supplying opening is made in the cover, and a stirring spatula for stirring the surface of the melted solder is set up wherein the nozzle is provided with gutters along the longitudinal direction of the nozzle on both sides thereof, the gutters being inclined toward the side.
A jet solder tank comprising a heater for heating a solder and a nozzle for jetting the solder melted by heating, said nozzle provided with gutters along the longitudinal direction of the nozzle on both sides thereof, the gutters being inclined toward the same side, wherein a dross reservoir is covered with a cover, a non-oxidizing gas supply opening is made in the cover, and a stirring spatula for stirring the surface of the melted solder is set up inside the cover.
