Start with solder wick, which is a fine braid of copper strands that have been coated with flux. Capillary forces cause molten solder to wick into the braid. Most metals develop an oxide layer when exposed to oxygen that repels solder. This process gets worse at higher temperatures. The flux cleans off the oxides so the solder will adhere to the metal and be drawn into the braid.
How to Choose a Solder Sucker
Bulb Solder Suckers
Bulb suckers consist of a rubber bulb and a small pipette. You squeeze the bulb to suck up unwanted solder. This is the crudest and most inexpensive type of solder sucker on the market.
Plunger Solder Suckers
Plunger solder suckers feature a spring-loaded suction system. They are typically pen-shaped. In most cases, desoldering plungers feature triggers or buttons that can be operated with one hand. The plunger sucks unwanted solder into a small reservoir. When the reservoir is full, it must be opened and emptied. Plunger suckers are the best pick for home-based soldering stations.
Vacuum Solder Suckers
Vacuum solders are electrically powdered. They are the most expensive and industrial solder removers. As such, they are typically used in professional soldering situations.
Some desoldering kits come with a role of copper desoldering braid. This twisted copper wire is sometimes covered in flux. The wire is used to lift unwanted solder offer of circuit boards. It is a disposable item. Desoldering braid is great for tackling unwanted solder that is located in hard-to-reach places.
Most solder suckers feature a small cylindrical frame that houses a mechanical pump. The frame is typically made out of metal or plastic. A solder sucker’s frame needs to durable and resistant to heat. You don’t want it to warp after coming in contact with hot solder or a soldering iron.
Solder sucker tips are typically made from nylon, silicone, or plastic. These materials wear easily but are flexible enough to create a tight seal on a circuit board. Opt for a solder sucker with a heat-resistant tip. Silicone tips are some of our favorites because they form a tight connection. On top of that, they can handle quite a bit of heat.
A solder sucker needs to muster up enough suction to lift heavy pieces of molten solder. A powerful spring-action plunger should do the trick. A good suction system won’t leave behind solder residue.
Being that you will also be handling the device around high temperatures, it’s also important that it is easy to hold and control. We strongly advise you to purchase a sucker with a slip-resistant grip and an ergonomic trigger. This way, you can eradicate unwanted solder without straining your hands or coming within harm’s way.
How to Desolder Joints
To desolder a joint, first cut off any used portion of the wick and when you use the wick, be sure to hold it by the bobbin as heat transfers quickly through the copper. Then add a small amount of solder to your iron tip. This bit of solder helps to transfer heat from the iron to the wick, acting as a heat bridge. It may seem counterintuitive to add solder to the iron when you’re trying to remove solder, but without this, it’s much harder to get the process started. Heat doesn’t travel well through a dry contact.
Hold the wick over the joint and gently press the iron on top of it. Continue holding the wick on the joint for several seconds to make sure all the solder is removed. This particular type of joint is very easy to desolder. It’s on what’s called a single-sided board and only has metal on one side. In contrast, many PCBs are two-sided and have plated through holes.
If you look up close, there’s still solder remaining between the pin the wall of the tube. Since this part has many pins, you need to make sure each one is completely free before trying to pull the whole part out, to avoid breaking a pin or a hole. Using a small screwdriver or pick, push gently to try to break the remaining connection. Make sure the pin is completely free.

If you can’t break the remaining solder connection, you may need to do more wicking. If you have access to the component side of the board, try applying the wick there too. Note that you have to add solder to your iron tip before using the wick each time.
Typically a leg will be pressed against one side of the hole. It can be helpful to apply wick on that side to try to remove the solder stuck behind the pin. Once you’ve removed as much solder as possible, try again to break the remaining sweat joint with a screwdriver or by wiggling the part.
How to Use a Solder Sucker
The next tool you have to use is the manual desoldering pump or solder sucker. To use this, first press down on the spring loaded plunger. Then align the nozzle over the joint to be desoldered and heat up the joint with the iron. Once it’s molten, pull the iron tip out, cover the hole with the nozzle and press the release button to activate the vacuum. The timing of this can be tricky as you need to engage the vacuum while the solder is still molten.
If you can touch the joint on the other side of the board, it can be much easier to heat that side while holding the solder sucker on the other. This removes the timing challenge.
Try to break any remaining solder connection by pushing on the pin. If there’s too much solder remaining to break the pin free quickly, you might have to use wick to clean up what’s left. If you don’t have any wick, it’s sometimes easier to resolder the hole and try again rather than continue to use the solder sucker on the mostly empty hole. If the joint is mostly empty, it will be difficult to get the remaining solder completely molten with the iron and also difficult for the solder sucker to create much of a vacuum.
Some joints are much more difficult than others to desolder. For instance, when you have a small hole with a very small clearance. Also, when a hole is attached to a ground plane, it can be difficult to heat up the joint sufficiently. A large component, like a capacitor, also adds to the heating requirements.
How to Use a Desoldering Gun
If you only have a wick or a solder sucker, your best bet is to use a higher temperature setting. Unfortunately, the higher the temperature and the longer the duration of desoldering operation, the greater the risk of damage. For cases with large ground planes or boards with four or more layers, a preheater can be used with a stand like this to warm the entire board before applying heat with an iron. Another difficult condition results from poor quality boards.
For all of these tough cases, or if you need to do a lot of desoldering, a desoldering gun is an ideal tool. It has an integrated iron and triggers activated vacuum pump. To use it, first, make sure there’s a good amount of solder on the joint to help heat transfer into it. Consider adding more if the joint is very small. Adding some flux at this point will also help.
Bring the gun down on the joint and wait for the solder to melt. Once it does, start moving in a circular pattern but avoid pushing down on the pad. Then activate the vacuum. Continue moving the tip in a circular pattern to help clear solder from all sides of the pin and then lift up the nozzle. The air and circular motion will help prevent the pin from refreezing to one of the sides. When doing ICs, it’s a good idea to skip pins to avoid thermal buildup in part.
Alternative Methods to Desoldering
Finally, some alternative methods and a few more tips. With solder wick, it can be very easy to damage a pad by moving the wick after it has frozen to the board. But many times, you can remove components without first removing the solder. For elements with nearby leads, you can heat both at once with iron and simply pull the part out. On resistors, you can pull one leg out at a time. For components with more than two leads, a hot air tool could be used to get all pins molten at once.
A special low melting point solder called Chip Quik will let you do the same thing with a regular iron. Just melt in some Chip Quik into every joint, alternate between each joint to keep them all molten, and then pull the whole part out. The Chip Quik allows you to keep every joint liquid all at once.
If you’re willing to sacrifice the part, cut each leg, remove the part, and then pull each leg out individually. It’s a lot easier to clean the hole that doesn’t have a lead in it.
Many of these approaches will be faster and pose less risk to the board than trying to desolder each pin individually.
FAQ About Solder Suckers
Why does my solder sucker clog?
It’s important to remove solder immediately after you’ve sucked it up. If you don’t, the solder will harden inside the tip and plunger.
What should I do if my solder sucker leaves solder residue behind?
Desoldering braids are engineered to pick up what solder suckers leave behind. Many solder suckers even come with a complimentary role of the desoldering braid. This twisted copper wire is perfect for reaching into tight places that solder suckers can’t access.
What should I do if the tip of my soldering iron melts?
Most budget-friendly solder suckers don’t come with tips that can handle lengthy desoldering sessions. With that said, silicone is one of the most durable and long-lasting materials used to make solder sucker tips.
How should I discard of my old solder?
Some people recycle their spent solder. They do this by melting down the old solder and creating new bars with it. If you’re not this savvy, discard the old solder in the trash.
How much do I need to spend to score a reliable solder sucker?
Modest solder suckers cost no more than $10. Meanwhile, industrial models range between $20 and $40. If you’re looking for a sucker you can use at home, $25 is a reasonable budget.
