Desoldering tools are essential for removing solder from electronic components on circuit boards. Common types include desoldering pumps, which are handheld devices that create a vacuum to suck up molten solder, and desoldering braid, a copper mesh that absorbs solder when heated. These tools help repair or replace components without damaging the board. Using the right desoldering tool can make the process easier and more efficient, ensuring that the circuit board remains intact for future use. Proper technique is important to avoid overheating and damaging sensitive components during desoldering.
