ABSTRACT:
A desoldering wick formed of tin-coated copper strands braided together. The wick is coated with a flux solution which includes a coloring agent such as a dye. In use, the extent to which molten solder has traveled along the wick is visually indicated by a color demarcation line between the portion of the wick still having colored flux thereon and the portion of the wick from which the colored flux has been discharged. The latter portion can then be cut off and discarded.
