A Desoldering Wire, also known as a Solder Remover Wire Roll or Solder Wick, is a specialized tool used primarily in electronics and soldering work to remove solder from soldered joints, electronic components, or circuit boards. Material: Desoldering wire is typically constructed with a high-quality copper wire core, which provides excellent thermal conductivity. This core is encased within a fine, braided mesh that is often made of copper or other heat-resistant materials. The braided mesh serves as the wicking element.
