Abstract
Abstract A solder-removing wick of copper strands having an exterior capillary surface of copper directly and substantially entirely coated with a noncorrosive flux. The wick is coated by contacting it with a flux solution that wets it sufficiently to substantially entirely coat its exterior surface while retaining the capillary properties of the surface.
