A soldering iron turns up in most board repairs here. Capacitors get swapped, broken tracks get bridged and chips get lifted and refitted. Skill matters more than kit, and a poor joint can cause a fresh fault, so many people practise on a scrap board before touching a machine they care about.

Lifting a surface-mount part is covered in five ways to remove surface-mount capacitors, which compares tools. For a snapped copper line, a PCB trace repair tutorial lists the tools and one common method. Fine pin work appears in the Voodoo card with lifted legs, a job for advanced hands. See also trace repair.

Hot irons burn. Fumes need ventilation, and flux and old solder are worth keeping off skin because old solder contains lead. Wash your hands afterwards and keep food away from the bench.
