Desoldering pumps are physically operating device that removes solder from PCB. The inverse procedure of soldering is desoldering. Therefore, the soldering process involves taking away PCB-mounted soldering and components. Every expert in the tech industry needs to know the method of desoldering a PCB and the best tool to choose. Besides, desoldering is an essential skill, and messing with the process isn’t improbable. Hence, we will tackle desoldering methods, advantages, the best pumps, and much more.
Generally, the process consists of several methods. Here are the frequently used methods.
Soldering and desoldering of electronic components
Desoldering braid / Solder wick
The methods work in amalgamation with a soldering iron to take away solder from solder modules and intersections. Usually, it’s a device comprising tinny copper cables layered with flux and weaved. Furthermore, the major benefit of the desoldering wick is that it's affordable and uncomplicated.
Also known as a solder sucker, it's a physically operated device that takes away solder. In addition, it uses force by pressing a switch to absorb molten solder positioned within the flame-retardant outlet.
The adaptable desoldering gun features a trigger. Therefore, pressing triggers a vacuity pump, sucking the molten solder out via the outlet. Similarly, like the desoldering pump, it generates a vacuum using an electric vacuum desoldering pump rather than a physical nozzle structure.

Hot-air rework station
The method pumps the air using an air pump via a pipe. Besides, using sizzling air, it desolders or solders electrical modules. In addition, to get the ideal outcomes, it regulates its airflow and temperatures using the nozzle.
Also referred to as hot tweezers, the tools desolder trifling modules with dual soldering rods such as capacitors, resistors, and SMD diodes. It’s easy to melt solders by adjusting the space manually within two desoldering tweezers heated tips.
A tool that allows you to mix and melt with existing solder on single element pins. Besides, it minimizes the solder melting temperature hence maintaining its molten longer. In addition, it enables you to remove SMD constituents easily without causing damage with soldering irons.
Soldering iron only
Having a soldering iron alone, you can desolder without using tools designed specifically for desoldering. Nevertheless, it can’t give exceptional results due to overheating the solder pads. Nonetheless, it’s a practical preference once there are no other accessible separate tools.
Benefits of Using a Desoldering Pump
- Its design best suits even the tiny spaces
- It eliminates the necessity of using a separate tool for desoldering the board and liquefying solder once equipped with a built-in heat gun.
- Ease the repairing and troubleshooting process
- The desoldering pumps don’t harm the entire PCB
- The sustainability feature specifies the PCBs recycling prospects for a different mechanical device
Drawbacks of Using a Desoldering Pump
The device has one major drawback: its rubber bulb-style desoldering pumps. Therefore, you may be required to remove faulty parts. In addition, the new PCB devices are ultra-small, making it hard to access some areas. Hence, you may have to find a tiny tip to complete desoldering process.
How to Use a Desoldering Pump
There are vital steps you must follow to use the tool successfully.
Step 1: Priming the Pump
First, begin by priming and galvanizing it several times so it can be ready for desoldering tasks. It will help to activate the pump.
Hold the desoldering pump firmly with your hand. Exert some pressure on the nozzle until it sticks in position, ensuring you press it slightly for suction. As a result, it zeniths the spring-loaded piston.
Step 2: Activating the Pump
On the side part, there is a black button; press it to actuate the pump. It discharges the spring-loaded piston, forming a burst eruption within the plunger. Brace your hand to maintain the plunger's steadiness when using the pump. Note that when releasing the piston, it produces extensive kickback.

Step 3: Desoldering a Joint
After fixing the angled nozzle, tighten the desolder pump. In addition, to ensure the solder liquidities, heat the solder. Put more solder on the linking angle of the desoldering iron to assist with the conduction of heat. Place the pump’s plunger very near to the liquefied solder. To activate the pump, you need to press the side release button. Redo the cleaning procedure till you see a spotless joint. To ensure no filtrate solder, use a solder wick to soak up the residue.
Note that, while desoldering the intersections, don’t use desoldering pump close to the SMT (small surface-mounted) constituents. Any suction and hotness surge might extricate the SMT constituents.
Step 4: Cleaning the Desoldering pump
Prime and actuate it for some time as you prepare for washing. Moreover, that ensures the bar shoves over the plunger and the solder doesn’t congest.
Besides, to wash it out more comprehensively, you can dismantle the pump holding the plunger by its gnarled verge. Unscrew it by twisting the counter-clockwise. After removing the nozzle, clean the pump interior.

How to Desolder a Circuit Board
The process might be a tiresome activity regardless of the reason. You need to use conventional equipment such as a solder sucker with sharp vision and firm hands.
The essential process involves;
Choose Precise Soldering Iron
It would help if you chose an iron that displays the digital temperature on the monitor. Besides, to ensure a level movement, ensure it has supple wiring and connection and has a clean tip. Else, it will decrease iron’s performance or its transmission property.
Purchase Proper Circuit Board Holder
It’s essential to have a holder proficient in maintaining the electrical circuit board. Besides, remember you are handling a tiny-sized space, thus, requiring a high level of precision. Therefore purchase a holder with added caution as the process has to be fast and error-free.
Use Solder Vindicated Magnitudes
Solder helps the procedure of getting rid of the board’s constituents easier. Therefore, as you use it in ideal quantities, you quicken the process of desoldering the board or getting rid of the components. Furthermore, if you use additional solder, it might need a higher temperature for melting hence added duration for solidifying. Thus, if you don’t use the suitable solder quantity, there is a high possibility of destroying the PCB. Therefore, select the proper quantity according to the PCB density.
You don’t want to overexpose yourself to vapors and lead for an extended period. Therefore, execute the desoldering procedure quickly.
Disconnect the Circuit Board
It's essential to disconnect the PCB or detaches rather than struggle with the device. Besides, you need to perform the process in a well-aired space. In addition, you will have a quick desoldering process and enhanced space for movement.
Best Desoldering Pumps
With so many desoldering pump brands available in the market, you might be wondering where to start. We have listed the four best ones to help you find the right one.
