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.

Claims

1. Copper strands elongatedly braided in the form of a consumable wick for drawing up molten solder by capillary action, said wick having an exterior capillary surface of copper, each strand having substantially along its entire length its exposed surface directly in contact and substantially entirely coated with a noncorrosive solder flux applied from a volatile solvent solution of 25 weight percent or less of said flux.

2. The invention according to claim 1 wherein said solder flux is a pine rosin, a rosin obtained from tall oil by removal of fatty acid components, a methyl ester of abietic acid, or a methyl ester of pimaric acid.
