Using solder suction, also known as a desoldering pump, is a straightforward process for removing molten solder from electronic components or circuit boards.
A solder suction tool works by creating a vacuum that pulls up liquid solder when activated. It's essential for tasks like replacing faulty components or correcting soldering mistakes.
Here's a breakdown of the typical steps involved:
Steps for Using a Solder Suction Pump
To effectively remove solder using a suction pump, follow these key actions:
- Prepare the Joint: Ensure the solder you want to remove is heated and in a molten state using a soldering iron. The tip of your iron should be touching the solder joint.
- Position the Pump: Place the nozzle of the solder suction pump as close as possible to the molten solder joint. Hold the pump in one hand and the soldering iron (keeping the solder molten) in the other.
- Activate Suction: Push the button on the solder suction pump. As mentioned in the reference, some of the solder gets sucked into the pump. The vacuum quickly draws the liquid solder away from the joint.
- Check and Repeat: Inspect the joint to see if all the excess solder has been removed. You may have to repeat it once or twice to get all the solder. Reheat the joint if necessary and repeat steps 2 and 3.
- Clean the Pump: After use, you'll need to remove the accumulated solder from the pump. To remove the solder from the pump, simply push the piston back. This expels the solidified solder collected inside.
Following these steps allows you to cleanly remove solder, making it easier to work on electronic projects or repairs.
Tips for Better Results
- Ensure the soldering iron keeps the solder molten throughout the process.
- Hold the pump nozzle firmly against the board or component pin to create a good seal for maximum suction.
- Practice on scrap boards first if you are new to using a solder suction pump.
By mastering the use of a solder suction pump, you can significantly improve the cleanliness and success rate of your soldering and desoldering tasks.
