Can you solder bare copper?

If you’re familiar with electronic assembly, soldering bare copper wire to a printed circuit board (PCB) is straightforward. Wire will solder readily to PCB pads and jumpers. Avoid soldering directly to component leads, as heat may damage them.

Do you need flux for copper to copper?

Remember that copper to copper brazing does not require a flux. Here are a few common combinations: Using Stay-Brite® Solder – Stay-Clean® Soldering Fluxes.

Is it necessary to use flux when soldering?

Do you need to use flux when soldering? When soldering circuit boards, or other electrical / electronic devices, yes – you need to use flux. Fortunately, almost all solder for electronics use has an internal core of flux, so you usually don’t need to add more.

Can you solder copper to copper wire?

Soldering copper is a fairly easy task for the homeowner to complete, providing that they follow a few simple instructions. Begin by laying out all the items containing copper wire that you wish to solder; plug in your soldering iron to let it heat up and put on all the necessary safety gear.

What is the purpose of flux when soldering copper?

The main purpose of the flux is to prepare the metal surfaces for soldering by cleaning and removing any oxides and impurities. Oxides are formed when metal is exposed to air and may prevent the formation of good solder joints.

What is the best solder for copper?

Copper is notoriously hard to solder. This is because it conducts heat away so well. The “best” (and most poisonous) is 60\% lead 40\% tin.

Will a soldering iron melt copper?

Just use solder. Soldering iron tips are commonly made of copper, so I would guess no. Copper melts at about 1090C. A soldering iron works at 250-300C.

Can you use too much flux when soldering?

Just as one can use too much flux when soldering, complications can arise when not enough flux is applied as well. Acting much like a paint primer, flux works to clean and prepare the surface for soldering and prevent oxidization during the process. Flux also aids in smoothly joining together joints.

Is it okay to 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. The best alternative to flux when soldering is petroleum jelly which is anti-corrosive and will not damage your material.

What can I use instead of flux?

Petroleum Jelly: The Best Flux Alternative for Soldering Chances are, you have a container of petroleum jelly somewhere in your house. Petroleum jelly has a wide range of uses and is one of the must-haves for any do-it-yourselfer. It is perhaps the best alternative for commercial flux you can use.

Can I use super glue instead of solder?

As others have said super glue is not conductive. You can buy conductive adhesive which is used when normal soldering is not practical. It can come in numerous styles (in a syringe, tube, or other type container). It is an option when a normal solder job can’t be done.
