You can also make your own.

Solder without solder. The simplest kind of soldering is just connecting two wires together. You can solder without flux. However, soldering can be done without additional flux in two cases:

If you choose a substandard solder, it may fail to. They get soldered automatically via bulk methods. You can do this by directly heating the wires, and all.

Place the end of the braid on the solder joint you need to desolder or on excess solder you need to remove and lightly press it. New method uses field’s metal to solder at room temperature. That is the simplest type of soldering without soldering iron.

But if the solder has the property of breaking down the oxide, you will not need flux to solder. This can be done by heating the wires directly and doesn't. One popular way to solder without using flux is to use petroleum jelly.

One of the simplest kinds of soldering you can design is by connecting two wires. All you need to do is apply a thick layer of petroleum jelly to the area you want to solder. So, for smaller electronic applications you.

Without a doubt, the type of solder that you choose to use on your pcb will impact its functionality. How to remove solder without a soldering iron step one: Ways to solder without flux petroleum jelly.
