The Best Solders for Electronics and Other Small Projects

Written by Edwin Jones / Fact checked by Andrew Wright

best solder for electronics

Nowadays, you can find many electronic solders online. You can even find models with an added solid rosin core flux with 2 percent flux content or more. This feature means you no longer have to dip it in flux every time you use it.

So whether you’re a beginner or a mid-level DIY electronics enthusiast, you can work more efficiently. You can then finish your work much faster and accomplish even more projects.

However, it is also hard to say what is the best solder for electronics today. There are many types of solder available, all of which work well with different applications. That’s why the solder would always depend on the type of electronic soldering you expect to do.

So, to help you find the right electronic solder for you, here are some things to consider when purchasing a tool to solder electronics.

  • Solder Type: You have to consider the project you’ll primarily be working on when choosing a solder.One type of solder is the most suitable solder for circuit boards with fine spaces between terminals, while another type of solder is for electronics electrical wiring.
  • Solder Diameter: Solder diameter is also one important consideration. Solders with a diameter greater than 1 mm can’t be used with small terminals. On the other hand, solders with a diameter less than 0.6 mm will use too much material and take too much time to apply.
  • Solder Melting Point: If you’re using an old or limited soldering iron, you also have to consider the solder melting point. Some solders require a higher melting point, especially lead-free solder. That’s why you might need a low temp solder if your soldering gun isn’t up to scratch.

Now, to help you pick the right electrical solder, check out the top twelve soldering leads and detailed buying guide below.

What to Look for When Buying Solder for Electronics


There are many types of solder you can find in the marketplace. However, the most common solder for electronics repair is leaded solders and lead-free solders.

One of the first things to consider is its brand—is it something you know and trust? But if you look beyond the name, you can still find quality solders from different makers. So if you want to try other brands, or are not familiar with the popular names in soldering, here are some things to consider.

  • Solder Type

First, before you find the right solder wire for your work, you need to consider the type of solder you need. For example, if you’re going to use it for computer board applications, it’s recommendable to have a lead-based solder. But if you’re going to use it for jewelry, you should use a lead-free solder instead.

Beyond the lead-based and lead-free solder, there are also different solder cores. There’s the acid core, which uses acid-based flux and is best for metal or steel surfaces. There’s also the rosin core solder that has a mild flux and is best for electronics.

Finally, you could get the solid core, which is usually used in DIY electronics. This option doesn’t have flux, so you should have your own ready.

  • Solder Diameter

Aside from the solder type, the solder size for electronics also needs to be considered. Solder comes in various diameters for all types of applications. For example, the top-tier solder for PCB is 0.019 inches in diameter. On the other hand, if you’re working with thicker cables, a 0.047-inch solder would be more suitable.

Picking the suitable diameter allows you to work more efficiently. You don’t have to apply solder multiple times, and you also don’t have to clean up extra solder when you’re using the exact size solder.

  • Solder Melting Point

Not all types of solder have a lower melting point. Most lead-based solder needs at least 365 up to 374 degrees Fahrenheit. This means it only needs a lower temperature soldering iron. However, the lead-free solder requires at least 419 up to 428 degrees Fahrenheit. It thus requires a medium to high soldering gun temperature.

  • Solder Package Weight

You need to know how much solder you’re going to need before you make a purchase. That way, you won’t run out of solder during a project. So if you’re soldering wire to circuit board, you need to estimate the weight of the solder you need.

Remember, it’s best to have a little bit extra solder than to run out of it while you’re working.

  • Tin-Lead Percentage

The tin-lead percentage may vary, depending on your need and application. If you want a polished finish, then you should consider a solder with a greater lead ratio. On the other hand, you should consider a lead-free solder if you want to avoid health risks.

Finally, I think you should consider soldering stations, they are also an important factor for your soldering to be perfect. Also, don’t forget to use soldering mats to classify electronic components.

Can I Use Plumbing Solder for Electronics


Typically, electrical solders like rosin core contain flux, while solid core solder needs extra flux. Plumbing solder is mainly acid-based and is only suitable for metal surfaces or nickel surfaces. It is not ideal for use in electronics.

The acid can produce metal oxides that can damage electronic components’ wiring or terminal connection and cause connection failures.

Is Silver Solder Good for Electronics

Based on Reddit UK, not all types of silver solder are suitable for electronics, as some silver solder needs a torch to melt it. However, there are silver solder alloy solders that can be used in electronics.

However, keep in mind that it requires a higher melting temperature which starts at 423 degrees Fahrenheit. Furthermore, it’s more expensive than other solders as it contains silver.

Is Lead-free Solder Good for Electronics

Yes, lead-free solder is also suitable for electronics. One of the great things about lead-free solder is it’s much safer than lead-based solder.

However, there are some downsides to this type of solder too. The lead-free solder has a higher melting point, costs more, and isn’t as polished as the lead-based solder.


Finding the best solder for electronics can be tricky because of the options available in the market. However, it is undeniable that modern technology makes soldering much easier and safer than ever before.

By looking through all the solder listed above, you now know what kind of solder to use for your projects and more.
