The most common use of electronic solder wire is for soldering electronic components onto printed circuit boards (PCBs). This includes soldering resistors, capacitors, integrated circuits, transistors, and other electronic parts onto the board.

Electronic solder wire is often employed in the repair and rework of electronic devices. This could involve fixing broken connections, replacing faulty components, or modifying existing circuitry.

Electronic solder wire is used to create electrical connections between wires, especially in cases where a more permanent and stable connection is required.
