Desoldering

maker

Desoldering is the process of removing solder and components from a circuit board.

expanded

Desoldering is critical in electronics repair and rework, enabling the removal of components for replacement or repair without damaging the circuit board. This process often involves the use of tools such as desoldering pumps or soldering irons with vacuum capabilities, making it essential for component prototyping and debugging in electronic manufacturing.

examples

Using a vacuum-based desoldering pump with a 0.79 mm (or 0.031 inch) nozzle to remove solder from through-hole components.

Commonly used in repairing circuit boards in consumer electronics such as televisions and computers.

Removing excess solder using solder wick with a width of 2.54 mm (or 0.1 inch) and a soldering iron set at 300°C (or 572°F).

Typically employed during circuit board rework, particularly when correcting solder bridges in surface-mount technology.
