  • Patent number: 7441687
    Abstract: The present invention provides a desoldering sheath and a method for making the same. The desoldering sheath is comprised of multiple metal ropes that are each made from two or more fine-gauge wire threads. The metal ropes are woven together to form a metal fabric that approximates the shape of a soldering tool tip. The metal fabric is formed by weaving the metal ropes around a mold that approximates the shape of the soldering tip. In the preferred embodiment, several such molds are strung together when the metal fabric is woven. After the weaving is complete, the fabric is then cut at those points along its length where the consecutive molds meet, and the molds are then removed, while the fabric retains the approximate shape of the molds. The desoldering sheath is mounted over a soldering tool tip and can conduct heat directly from the soldering tool to the solder and then absorb molten solder by capillary action, making desoldering a one-handed task.

  • Patent number: 7134590
    Abstract: A desoldering sheath that comprises at least one hollow metal wire molded to conform to the tip of a desoldering tool. In one implementation, the desoldering sheath is formed using a hollow metal wire that is coiled around a male cone-shaped mold. The coiled, hollow metal wire is then compressed between the male cone-shaped mold and a female cone-shaped mold to cause the hollow wire to retain the coiled shape. In use, the desoldering sheath is placed on the tip of a desoldering gun or iron and then heated. The heated desoldering sheath, while still on the tip of the desoldering gun or iron, is then placed into contact with solder. This causes the solder to melt and the desoldering sheath captures the molten solder by using capillary action to draw the molten solder into the hollow metal wire.
