FAQ: How To Remove Solder From Metal?

How do you remove stubborn solder?

Try twisting the solder wick into a point, so it can get inside the hole, add some flux to it, and place the iron on top the wick and see if that helps. Be sure the iron tip is clean, so it transfers heat. The trick with using a resistor lead or needle has worked for me as well. Flux helps here, too.

How do you remove solder without a pump?

Place your wick against the point where you want to remove solder, then hold your irons tip over that point. You’ll see the solder soak into the wires around the point where your iron is touching once it gets hot enough to melt.

What tool will remove solder?

A desoldering pump, colloquially known as a solder sucker, is a manually-operated device which is used to remove solder from a printed circuit board. There are two types: the plunger style and bulb style.

What can I use instead of a solder wick?

To make your own solder wick you will just need a piece of stranded copper wire and some flux. And now you just made a solder wick from a piece of copper wire, you can use it as the usual solder wick.

Can you reuse solder?

Yes. You still need to clean and flux it for reuse, and you may need to bang it on a hard surface while hot to remove excess solder so the new pipe can fit inside, but yes, unless it is split or otherwise defective, it is reusable.

Do you have to remove old solder?

Unless the solder creates short circuits or structural problems, you can heat the solder until it melts and then pushes your components through. The solder will still work. You will even get a connection to it. However, if the old solder will cause problems, you have no choice but to remove it.

Does flux remove solder?

The main purpose of using flux however is to remove oxidized metal from the surfaces to be soldered, seal out air thus preventing further oxidation, and by facilitating mixing it improves wetting characteristics of the solder.

Can you remove solder without flux?

Yes, solder can be used without flux. To do so, you will need something other than flux to break down the oxides on the metal surface, without which your surface may be damaged or not properly cleaned.

Can you Desolder without a desoldering tool?

A soldering iron is little more than a heated piece of metal used to render solder into its liquid state. Having a soldering iron can make removing solder from a piece of pipe or electronic circuitry much easier, but it is by no means a necessary tool.

How do you Desolder without a tool?

Use something called solder wick. Its a rosin flux impregnated fine copper braid – comes in several widths but it will wick the solder out of joints. Usually cut the leads of the component being removed, heat and pull the leads out, then use the wick to absorb the solder out of the holes.

What is flux for soldering?

Flux is a chemical cleaning agent used before and during the soldering process of electronic components onto circuit boards. The flux also protects the metal surfaces from re-oxidation during soldering and helps the soldering process by altering the surface tension of the molten solder.

Is it necessary to use a soldering iron when desoldering?

Step 1: How to Use a Soldering Iron to Desolder 1. Using the tip of the soldering iron will remove the copper plating from the PCB. Pros: You need nothing but a soldering iron, and the components can be reused. Cons: You may damage the board if you leave the soldering iron on it for too long.
