How to Use a Solder Sucker: A Complete Guide

Solder suckers, also known as desoldering pumps, are essential tools for anyone working with electronics. This tutorial will walk you through the proper way to use a solder sucker step-by-step.

Step 1: Gather Your Materials

Ensure you have all the necessary tools and materials:

• A soldering iron
• A solder sucker
• A clean, flat work surface
• A heat-resistant mat or workbench
• Safety goggles and gloves

Step 2: Prime the Pump

Note: Before using a desoldering pump for the first time, practice priming and activation.

• Firmly hold the desoldering pump.

• Press down on the plunger until it locks into position.

This initiates the suction of the spring-loaded piston.

Step 3: Heat the Solder Joint

Plug in your soldering iron and let it heat to the appropriate temperature. Place the tip on the solder joint and allow the solder to melt completely.

Step 4: Position the Solder Sucker

While the solder is still molten, position the tip of the solder sucker over the solder joint. Keep the nozzle close without touching the component leads or circuit board.

Step 5: Activate the Pump

To activate the pump, press the side button. This releases the piston, creating a burst of suction.

Step 6: Desolder the Joint

Note: Avoid using the pump near small surface-mounted (SMT) components.

1. Prime the pump by depressing the plunger.

2. Heat the solder joint until liquified.

3. Position the pump’s nozzle close to the molten solder.

4. Press the side button to activate the pump.

Repeat until the joint is clean. Use solder wick to soak up any remnant solder.

Step 7: Clean the Desoldering Pump

Prime and activate the pump a few times to ensure no solder blockage. For a thorough clean:

• Grasp the nozzle by its knurled edge and twist counter-clockwise to remove it.
• Clean out the pump interior.

Tips for Using a Solder Sucker

• Work Quickly: Move fast when using our best solder sucker, as solder solidifies quickly.
• Maintain Your Soldering Iron: A clean, well-maintained soldering iron tip is crucial for efficient desoldering.
• Use the Right Temperature: Avoid overheating the board or components.
• Safety First: Always wear safety goggles and gloves when working with solder and electronics.
