Description A desoldering pump, or solder sucker, is a manually operated tool that removes molten solder from a joint using a vacuum. It features a spring-loaded piston that, when triggered, creates a suction to pull molten solder into a reservoir. To use it, you heat the solder with a soldering iron and then quickly position the pump’s tip to suck up the melted solder, facilitating the removal of components from a PCB or correcting bad solder joints. How it works: Melt the solder: Use a soldering iron to heat the solder joint until the solder melts. Position the pump: Place the desoldering pump’s tip against the hot, molten solder joint. Activate the vacuum: Trigger the pump’s button or piston, creating a vacuum that rapidly sucks the molten solder away from the joint. Key characteristics: Manual operation: Typically powered by a manually operated piston or plunger. Vacuum creation: The tool works by creating a powerful suction to draw molten solder into its reservoir. Heat-resistant tip: The tip is made of fireproof or high-temperature resistant material, such as aluminum, to withstand repeated contact with hot solder. Types: Commonly available in a plunger style or a bulb style. Purpose: Component removal: Allows for the clean removal of components from a printed circuit board (PCB) without damaging the board or component pads. Reworking joints: Useful for correcting excess solder or faulty connections on a PCB.
