How to use electric soldering iron correctly for welding
Welding technology is a basic skill that DIY enthusiasts must master, and requires more practice to become proficient. Grind the solder pads and component pins clean with fine sandpaper and apply soldering flux. Dip an appropriate amount of solder with a soldering iron tip, touch the solder joint, and wait for all the solder on the solder joint to melt and immerse the component lead head. Gently lift the soldering iron tip up and away from the solder joint along the component pin. Today we will talk about how to use an electric soldering iron correctly for welding.
The use of electric soldering irons can be divided into several situations:
1. Solder the components onto the circuit board (or remove them)
2. Solder the wires to the circuit board
3. Welding between wires is most common in some electrical appliances, such as fans.
We also need to mention here that when obtaining the components, do not rush to use an electric soldering iron for soldering.
The pins, wires, and circuit boards of the components should be treated first, just like using 501. If you don't clean and smooth the bonding surface, you will definitely curse "buying fake goods". Although there are many fake goods these days, sometimes it's just because you're not using them well.
However, as far as components are concerned (I mean when installing new components), we should be grateful for modern technology. Modern technology does a great job of surface treatment, so many times we don't need to do any treatment on the components. For example, I basically don't dry them anymore, but initially we used an eraser to wipe them carefully, added a layer of tin, and even wiped them with rosin alcohol solution
But if it's an old component removed from the circuit board, it's best to dispose of it. Use an electric soldering iron to remove the old tin, or heat it up and flatten the pins. If you don't do this, you may never be able to insert the circuit board again.
The line is not that simple anymore.
There are many types of wires, and no one knows which one you will encounter. Some wires are very annoying and difficult to solder. If you directly solder them, it will make you cry without tears.
