  • Method of separating oxide from dross, device for separating oxide from dross, and jet solder tank
    Patent number: 6719144
    Abstract: 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).
