Let’s go.

Limiting beliefs that hold you back

I think that the biggest obstacles between a person and achieving his goal are the limiting beliefs he carries with him.

If we work on those limiting beliefs trust me the rest of the process is not that hard. The rest of the process is just practicing with persistence.

Like if you start practicing soldering. Sure at the start you will suck. But with time and practice, you will become better.

Following are some beliefs that I think a beginner has:

Soldering is hard, and I am not smart enough to learn it
It will require a lot of money to buy the tools
How can I be good at soldering when I don’t know about electronic circuits
Soldering is very complicated
I don’t know where to begin

Maybe there are more. But you got my point.

Let me tell you straight away. Your own mind creates these beliefs. It has nothing to do with the reality that much.

Like how do you exactly know soldering is hard? While in reality, you didn’t even solder for a minute.

So, how to start soldering with a realistic approach?

The answer is, you didn’t try soldering in your life. So at first, it will be hard, and you will suck no matter how smart you think you are.

It is reality.

But if you are genuinely interested and ready to put in the hard and persistent work. I guarantee you will become good in a matter of a few months.

Of course, you will make mistakes. And that is fine.

Of course, you will burn a few circuit components. And your first final finished circuit will look like garbage. There will be joints with too much solder, open joints, cold joints, and God knows what other terrible joints as well.

And that is totally fine.

What is soldering and its worth

Now that we have got our beliefs right, it is time to actually get to know what is soldering. Is it really worth pursuing?

Soldering is the process of joining two connections correctly. This definition seems very simple, and it is because soldering is that easy.

All we need is a tool that can be heated to a certain temperature, and a soldering wire which can be melted using that heated tool. Upon melting, it creates a permanent joint between the connection we want to make.

The heating tool is a soldering iron. The soldering wire is solder. And connections can be anything. It can be two wires, electronics components, PCB joints, etc.

We take our soldering iron, melt the solder, and make connections. This is what we call the art of soldering.

Is soldering worth it?

Yes, absolutely.

We are living in an era where you can see yourself that there are electronic products everywhere.

These electronic products have PCB inside them.

On PCB various types of electronic components are soldered. Without soldering there would be PCB, and no such commercial electronics products.

So, if you learn the skill of soldering, chances are you may get a job at various electronics manufacturers and companies.

With electronics products, there comes the repair. With time these products became out of order and need to be fixed instead of buying a new one.

To repair these products you need the skill of desoldering and soldering. If you master these skills you can open your repair shop or can get a job in the repair field.

Besides learning to solder for getting a job, I can tell you that it is a very interesting hobby as well. You learn so much about electronics and how circuit components work together, and so much more.

Setting up the essential lab

Basic soldering tools

Step by Step soldering process

Safety and health

Gather the tools

The first step toward soldering is to gather the needed tools. Let’s discuss the tools that you will need for soldering.

1. Soldering iron

A soldering iron is a tool that is used for soldering. As a beginner selecting an iron is very crucial. Select soldering of appropriate wattage and power. A 40 to 60W soldering iron is suitable for most soldering projects.

Investing in a soldering iron with a comfortable grip and a stable stand is essential as it is important for safe soldering.

2. Solder

Select an appropriate solder for your project. There are different types of solder such as leaded solder, lead-free solder and rosin-core solder. The leaded solder has a low melting point but it has environmental concerns due to the use of lead.

Now a day lead-free solder is recommended but it has a high melting point. The rosin-core solder has flux in its core which makes it a better choice for soldering projects and minimized the use of flux. Use rosin-core solder for electronics projects.

3. Soldering Stand

Invest in high-quality and reliable soldering stand. It reduces the risk of accidental contact with hot iron. It will hold the iron when the iron is not in use.

4. Soldering sponge

During soldering, the iron tip accumulates dirt and can be oxidized so keep the wet or brass sponge with you to clean the tip of soldering iron.

5. Personal protective equipment

Make use of personal protective equipment such as safety glasses to protect your eyes from solder splatters and safety gloves are optional, but they can protect your hands from accidental burns.

Safety precaution

Work in a well-ventilated area to avoid inhalation of harmful fume which is released when hot iron comes in contact with solder. Be cautious of the hot soldering iron and avoid touching the tip or placing it on flammable surfaces.

Make use of a soldering iron stand when the soldering iron is not in use to avoid accidental burn. Wear safety glasses and gloves to protect yourself.

Step-by-step soldering

Now let’s discuss the step-by-step procedure to solder electronic components.

1. Clean the tip

Before starting soldering, clean the soldering iron tip with a wet sponge or brass sponge to remove solder residue and oxidation. This will maintain the iron tip and will enhance the heat transfer quality of iron.

2. Heat the iron

After cleaning the tip, plug in the soldering iron and allow it to heat up to the appropriate temperature for your soldering task. Make sure the iron is heated enough to create strong soldering joints.

3. Tin the tip

After heating the iron, apply a small quantity of solder on the tip’s surface. This technique is known as “tinning” and enhances heat transfer while soldering. This also reduces the accumulation of oxidation on the tip and increases the tip lifespan.

4. Prepare the components

Now it is time to prepare the components, clean them before soldering and align the components you want to solder and ensure they fit correctly.

5. Apply flux

Apply the flux if needed, flux is a chemical compound that improves wetting and enhances the flow of molten solder. If you’re working with old or oxidized parts, adding a bit of flux to the joint will help the solder flow more easily.

6. Heat the joints

Now next step is to heat the joints. Position the soldering iron’s tip on the joint where the component and board meet. The iron should touch both the component lead and the pad on the board.

7. Solder the joints

After heating the joints now time to apply solder. While holding the iron steady on the joint, touch the solder wire to the opposite side of the joint (not directly on the iron’s tip). Allow the solder to flow and cover the joint evenly. The solder should melt and flow smoothly around the connection.

8. Remove the solder

When the connection or joint is fully covered with solder, remove the solder wire and soldering iron from the joints. Hold the joint steady until the solder has cooled and solidified.

Soldering tips

Here are some soldering tips that will help in creating reliable and strong soldering joints.

Try to practice on scrap electronics or soldering practice boards before working on important projects.
Don’t apply too much solder as it will lead to solder bridges or short circuits and also too little solder will create weak joints. Apply the appropriate amount of solder.
Remember, patience is essential when soldering. Take your time and work steadily to ensure your joints are neat and reliable.

Conclusion

As a beginner, you may be worried before starting soldering but if you have the right soldering tools and enough knowledge about soldering then you are ready for soldering and by practice, you can become an expert in it.

Grap a 40 to 60W soldering iron, a rosin-core solder, a damp sponge, a soldering stand, a practice board and some components to start your soldering journey. Don’t forget to take appropriate safety precautions as the heat of soldering can cause any accidental burn.

Clean the tip of the iron and heat it to a set temperature. Now align the components in the board and heat the joint with the help of soldering iron and apply the solder to the joints. After the solder covered the joint remove the solder and extra solder should be removed after the joint is cool down.

Remember, practice makes perfect. Soldering can be a bit challenging at first, but with time and experience, you’ll become more proficient.
