Title: Method of flux coating metal wick

Abstract: A metal wick to be used for the absorption of molten solder is deoxidized and flux coated by a process that does not involve the application of heat to the wick or the flux. In one embodiment the wick is cleaned by heating in a reducing atmosphere and is then immersed in a coating bath containing a solution of a rosin flux in an organic solvent. On leaving the bath the welted wick enters a low-pressure chamber in which the solvent rapidly evaporates at room temperature. In another embodiment the deoxidized wick is coated with comminuted solid resin by electro-static means.
