Learn moreThere are times when you want to clean your circuit board thoroughly; you might need to remove old solder. But to remove solder, you will need a desoldering tool to work with a soldering iron. But what are those tools? Now, if you don’t know the different tools for desoldering, then you have come to the right place! If you go through this article, you will learn about different techniques and tools you can use to desolder. Then you can decide on which method or tool you will be using. And once you are done with deciding, you can start removing solder from different components and boards. However, before learning about different types of desoldering, you must know what desoldering exactly is. So, let’s begin!
In this post we'll cover:
- What is Desoldering?
- What Are the Tools Required for Desoldering?
- Ways to Remove Solder
- Desoldering Bulb Method
- Desoldering With Drills
- Desoldering With Chip Quick
What is Desoldering?Desoldering is the method of removing solder and components that are mounted on a circuit board. This process is mainly used to remove solder joints. The application of heat is required here.
What Are the Tools Required for Desoldering?These here are the set of tools that you’ll be needing to get rid of that unnecessary solder.
- Desoldering pump
- Desoldering bulb
- Heated soldering tweezers
- Desoldering braid or wick
- Removal fluxes
- Removal alloys
- Heat guns or hot air guns
- Rework stations or a soldering station
- Vacuum and pressure pumps
- Various picks and tweezers and many more.
Ways to Remove Solder
Braid Method of DesolderingIn this method, when you heat the solder, the copper braid soaks it up. You must keep in mind that a quality solder braid always has flux in it. Also, clean the soldering iron before these steps. The process follows the following steps: Choose the Size of the Braid Firstly, you have to choose the size of the desoldering braid wisely. Use a braid that is the same width or a bit wider than the solder joint you will be removing. Use a soldering iron To use the braid, make a hole in the solder joint which you want to remove and lay the braid on it. Then hold a soldering iron up to it so that the solder wick can absorb the heat and transfer it to the joint. Always select a quality solder braid Now, in this process, having a quality solder braid is essential. Or else, it will not be able to soak the heat. However, if you have a weak quality solder, then don’t get disheartened. You can fix it by adding some flux. You just have to add flux to the part of the braid which you will be using. And you must do it before you put it on the joint. Moreover, if you feel like the joint does not have enough solder, you can add fresh solder to the joint beforehand. You will observe a change in color When the solder joint gets melted, you will observe that the molten metal soaks into the braid and turns it to a tin color. Spool out more of the braid and move to the next section and continue the process until the joint is completely absorbed and removed. Remove the soldering iron and braid together Once the molten solder is removed, lift both the soldering iron and braid together in one movement. When you remove the iron before the braid, the solder-filled braid might cool off rapidly and solidify back to the project.
Pump Method of DesolderingThe desoldering pump, also known as a solder sucker or solder vacuum, is used to vacuum small quantities of melted solder when you melt the joints. The manual type is the most trusted version of this tool. It has a reliable suction power and can rapidly remove melted solder. This is the most popular method among the ways to remove solder without a soldering iron. Set the spring At first, you have to set the spring of the solder pump. Heat the soldering iron to a certain temperature. Heat a soldering iron for about 3 minutes. Make a gentle contact between the soldering iron and the solder joint you want to remove. Use the tip of the iron. Keep heating the solder until it melts. Use the solder sucker. Now, touch the tip of the solder sucker to the melted solder and solder pad. Try not to apply any pressure. Push the release button After you push the release button, the piston will shoot back quickly. This will create a quick suction that will pull the melted solder into the pump. Cool off the melted solder Give the melted solder sometime to cool off and then empty the suction device into the trash.
Iron Method of DesolderingThis method is quite similar to the methods above. It requires a one-piece desoldering iron. The iron comes with a built-in suction component that vacuums away the melted solder. Apply the tip of the preheated iron to the solder joint you want to remove. As soon as the solder liquefies, the running solder pump will take away the melted solder.
Heat Gun Desoldering Method
- First, remove the PCB from the casings.
- Now, you have to heat the area with your heat gun. Here, you have to keep in mind that you must place the item on something inflammable; also the area around it must be inflammable.
- When you are heating, you will observe the solder turning shiny; that means it’s getting melted. Then, you can remove the solder using tweezers or similar tools.
- You can now place it in a safe place to cool off.
