If you are thinking of learning a new skill, soldering should be on the list. Soldering is a skill you might find useful in the future, especially if you are a DIYer. It can help you fix things at home and use it to do various projects.
While soldering is essential, there is an occasion wherein you’ll have to do some desoldering. You could desolder a joint if you learned the basics of soldering. But of course, you have to know the tips and tricks for a good outcome.
How to Desolder
Step 1: Complete your Equipment
First, gather all the equipment you will need for desoldering. You have to get a soldering iron and a device to remove the solder. The soldering iron will melt the solder and create a new joint. Now, be warned that not all soldering irons are good for desoldering. Choose an iron with 15W to 30W range, especially when working on a circuit board. High-powered iron can damage the component of the board. Thus, soldering guns, soldering stations, and commercial solder irons are not ideal for this task. If you feel confused about which soldering iron to use, you can ask help from Hand Tools For Fun.
Also, remember to get your safety gear. Soldering iron produces immense heat that can cause injuries. Make sure to wear protective gloves, and glasses while performing the task. Likewise, avoid wearing loose clothing and remove any debris from your working station.
Step 2: Prepare the Surface
Prepare the surface you will have to desolder. Remove any grease, varnish, and glue on the area before you begin heating.
Step 3: Heat the Iron Tip
Prepare the iron tip. Let it heat, and once it reaches the desired temperature, rest it against both the components. Immediately remove the iron after a second or two. However, you’ll have to let it stay longer for larger soldering pads.
Step 4: Remove the Solder
There are two devices you can use to desolder a joint; these are solder sucker and solder wick.
When using a solder sucker, push down plunger and lock it into place. The tool produces a ‘click’ sound indicating a lock. If not, you can push the small plug of the solder out of the nozzle. Once the device is secured, put the nozzle in the molten solder and press the button. The plunger will suck the solder from the joint. You will have to repeat this process a few times to remove the solder.
If you are using a solder wick, you have to heat the device first. Before starting, lay the wick over the joint while holding the iron’s tip on the wick. Once it heats up, the wick will slide, and the solder will flow into it. Replace the wick when filled with solder by cutting the used section and using a new portion of the spool.
Step 5: Clean
Clean the solder pad to remove excess resin and solder. However, make sure to use the right tools for cleaning, like the 000 steel wool.
While soldering is fun and a great skill to have, you also need to learn how to desolder. If you have more questions on desoldering, you can ask help from Hand Tools For Fun.
