Beschreibung
Zusammenfassung:	The present invention belongs to the technical field of solder fluxes, and in particular relates to a water-soluble flux and a copper material pickling method. The water-soluble flux provided by the present invention includes an organic acid, an alcohol ether solvent, and deionized water. The organic acid is used as an active component of the present invention, and under the action of the alcohol ether solvent, oxides and impurities on the surface of a part to be welded can be sufficiently removed, and adhering residue of an acidic substance on the surface of the part to be welded can be reduced. In the process of tin plating of the part to be welded treated by the water-soluble flux provided by the present invention, the splash of tin liquid can be effectively inhibited, and the utilization rate of tin is improved.
