A desoldering pump, or solder sucker, is a manually operated tool with a spring-loaded piston that creates a vacuum to quickly remove molten solder from a circuit board for component removal and repair. The process involves priming the pump, heating the solder joint with a soldering iron, and then pressing the pump's button to suck the fluid solder away, leaving the connection clean.
Features
- Prime the pump: Push the piston down until it locks into place, creating a vacuum.
- Melt the solder: Heat the soldered connection with a soldering iron until the solder becomes molten.
- Apply the pump: Quickly place the fireproof tip of the desoldering pump over the molten solder joint, ensuring a good seal.
- Activate the suction: Press the trigger button on the pump. The piston will rapidly spring back, creating a strong suction that pulls the liquid solder into the pump's internal chamber.
- Repeat as needed: You may need to repeat this process a few times to remove all the solder from the joint.
- Remove the component: Once all connection points for the component are clean, it can be easily removed from the PCB.
- Empty the pump: After use, push the piston back in to eject the collected solder from the pump.
