A soldering iron is a tool with a metal tip that gets really hot. We’re talking like 350 -400 degrees Celsius , Its job is to transfer heat to solder wire , transistor leads other components legs and copper pads on PCBs ,to join them.
There are many ways to make good solder connections. For the beginner, it’s hard to do, I’m going to explain how I do it.So Let’s get started!
Soldering iron stand
Before plug it in Place the soldering iron in its stand
2. Wait for the soldering iron to heat up
The time depends on the wattage and the type of iron.
You use a damp (not dripping) sponge to wipe the tip of your
soldering iron clean before soldering each component.
Hold the iron in your dominant hand and a long piece of solder in your other hand. When soldering two components together, you want to touch the area where they join with the soldering iron. Hold it there for about a second, then slide the solder underneath the tip of the iron, sandwiching it to the PCB (refer to above image, cursor points to solder). Hold it for another second or two, feeding in how much solder you need. This amount will vary depending on the project, application, and diameter of the solder, so check your instructions and study the pictures to get a good idea of the end result.
5. Tip cleaner
If you don’t keep the iron’s tip clean, it might actually repel solder — making it bead up and staying away from where you want it to go. When the tip is too grungy to be cleaned by simply wiping it on the damp sponge, use a tip cleaner paste to chemically clean it
6. Solder wick:
Sometimes you have to desolder a bad joint and then resolder it. To help remove the bad solder, you can use a solder wick, which is
a flat, braided piece of copper that soaks up solder.
There are fancy clamps you can buy called third-hand clamps to hold components while you solder them. Personally, we just use a vice and an alligator clip; they do just fine!
- A soldering iron can heat to around 400°C, which can burn you or start a fire, so use it carefully.
- Unplug the iron when it is not in use.
- Solder contains lead, which is a poisonous metal. Wash your hands after using solder.
