Solder and flux

When joining two metals in a soldering process, like used in PCB assembly, flux is required to achieve a true metallurgic bond. That ensures the solder joint doesn't crack or come loose even with the day-to-day wear-and-tear.

Is flux and solder the same?

What is Flux and What is the Difference Between Flux and Solder? While solder is used to assemble components onto your circuit board, the flux is used prior to assembly to prepare and help your board through the soldering process.

Why do we use flux in soldering?

Soldering. In soldering of metals, flux serves a threefold purpose: it removes any oxidized metal from the surfaces to be soldered, seals out air thus preventing further oxidation, and by facilitating amalgamation improves wetting characteristics of the liquid solder.

Can you use Vaseline as flux?

Can You Use Vaseline as Flux? Yes, Vaseline works just as well as commercial flux, and you can even buy a generic brand. Petroleum jelly is primarily made from waxes and mineral oils so that it won't corrode your components. Plus, it cleans away the gunk and eliminates metal oxides that could compromise your bond.

Can vinegar be used as flux?

Vinegar is acid. That is exactly what fluxes are. Use it for a flux if you want.

What can I use instead of flux?

A: The classical fluxes were wood rosin and acid solutions - both intended to protect even etch the top surface when it gets hot and is likely to oxidize. Instead, you can place a puddle of solder on one (horizontal) surface, and with a pen knife blade, scratch the metal under the blob.

Do you have to use flux when soldering copper?

You “can” solder copper without flux, without scraping (sanding or filing) clean the two surfaces, and without ensuring there is a close even fit between the two surfaces for the molten solder to wick into and provide a quality joint.

How do you use flux to solder?

The metal of the parts and the middle of the solder need to come into direct contact with each other

What is flux made of?

flux, in metallurgy, any substance introduced in the smelting of ores to promote fluidity and to remove objectionable impurities in the form of slag. Limestone is commonly used for this purpose in smelting iron ores. Other materials used as fluxes are silica, dolomite, lime, borax, and fluorite.

Is flux toxic?

health problems if fumes are inhaled or if flux gets on the skin. Short term problems can include nose, sinus, eye and throat irritation and skin rashes, and long term problems may include asthma and dermatitis.

Can you use a paperclip as solder?

Point it's good for getting right in the joint for soldering.

What should you not do when soldering?

1) Soldering Iron Safety • Never touch the element or tip of the soldering iron. It is very hot (about 400°C) and will burn. Hold wires to be heated with tweezers, pliers or clamps to avoid receiving burns from objects that are heated. Keep the cleaning sponge wet during use.

What causes solder not to stick?

This issue is usually caused by the soldering iron being set to an improper temperature, or the iron itself has a wattage that is too low for the solder size you are using. If you notice your solder isn't sticking, check your solder material and compare it to the wattage of your soldering iron.

How do you clean copper after soldering?

Combine about a tablespoon of salt and a cup of vinegar and then add enough flour to make a paste. Apply the paste to a still and wait. Leave sit for 30 minutes, wash off, and repeat the process if needed.

What metal Cannot be soldered?

Solderability	Metal

Why is the solder not sticking to copper pipe?

Most likely you don't have the base metal hot enough for the solder to wet it. Make sure the pipe is empty, and try waiting a bit longer before applying the solder. The base metal should be hot enough to melt the solder directly.
