Desoldering Pump

A desoldering pump, also known as a solder sucker or solder vacuum, is a handheld tool used for the removal of solder from electronic components or circuit boards. It is commonly used in electronics repair, prototyping, and other soldering applications.

The desoldering pump consists of a hollow cylinder or tube made of heat-resistant material, typically metal or plastic. It has a plunger mechanism and a nozzle at one end. The plunger is operated manually by pressing a button or trigger, creating a suction force.

To use a desoldering pump, you heat the solder joint with a soldering iron until the solder becomes molten. Then, while the solder is in its liquid state, you position the nozzle of the desoldering pump over the solder joint and press the button or trigger. The plunger is quickly released, creating a vacuum that sucks the molten solder into the pump.

The nozzle of the desoldering pump is designed to be heat-resistant and narrow, allowing precise positioning and effective removal of solder from small components or tight spaces. Some desoldering pumps have interchangeable nozzles with different sizes or shapes to accommodate various soldering tasks.
