Zusammenfassung:	The invention relates to a water soluble flux soldering taking colophony as a carrier and a method for preparing the same. The method is characterized by using acrylic colophony, ethanol, Tween 20, malic acid, dimethylamine hydrochloride, ethanol amine and the balance deionized water as raw materials; adding ethanol into a container of a stirrer first; sequentially adding the acrylic colophony, the Tween 20, the malic acid and the dimethylamine hydrochloride; after complete dissolution of the raw materials, dropping the ethanol amine till the PH value reaches 9; adding the balance deionized water; stirring the mixture at a high speed of 3,000 r/min for 10 minutes; and obtaining the product of water soluble flux soldering by filtration. The product has the advantages that: the welded surfaces are insulated and have high resistance; a printed board has good dryness and is easy to clean; and the cost is low and the preparation method is simple.
