Use a small paintbrush or your fingers to scoop up a small amount of soldering flux. Spread the flux over the area you will be soldering, making sure to cover the wires fully. Wipe any excess flux off your fingers or brush before soldering. Soldering flux is only corrosive once it is heated up and in its liquid form.

Can you use too much flux when soldering?
One, using much more than needed will basically drown your joint making it hard to heat to the right temperature, two, flux needs to be removed before a part is returned to service so every bit used that is more than needed makes for more clean up. Excessive flux is just that much more you have to clean off your work.
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 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.
Do you flux both sides?
Wipe both sides of the joint with flux After a thorough cleaning, coat the pipe and fitting with flux before heating the joint. This helps solder flow into the joint. We recommend tinning flux.
How long can flux sit before soldering?
Been working with a plumber mate of mine today, he says two days tops, but depends on conditions and manufacturer.
What is the best temperature to solder?
Make sure the surfaces to be soldered are clean. Turn on the soldering iron and set temperature above the melting point of your solder. 600°- 650°F (316°- 343°C) is a good place to start for lead-based solder and 650°- 700°F (343°- 371°C) for lead-free solder.
Why does my solder not stick?
A classic reason solder won’t stick to something is because you’re not getting it hot enough. My interns come to me with this problem all the time. Make sure the tip of the iron is nice and shiny. Touch some solder on it, and it should melt almost instantly.
What can I use if I don’t have flux?
Petroleum jelly is the best effective alternative to commercial flux. Its waxes and mineral water ingredients make it antioxidant thas why you can easily use it as a soldering flux.
Can you apply flux with finger?
WARNING: Do not apply with fingers. Chemicals in the flux can be harmful if carried to the eyes, mouth or open cuts. Use care in applying flux.
Why do plumbers use flux?
In plumbing, flux is a compound used as part of soldering a pipe joint. Crucially when heated, the acidic flux draws molten solder deep into the cracks of the joint and forms a clean bond with the metal. Flux is an essential part of allowing the solder to flow evenly and fully around a well soldered joint.
Why does flux draw in solder?
Flux typically promotes bonding between the base metals and the solder. It does this by cleaning the metal (removing surface contaminants), deoxidizing the metal, and preventing further oxidation.
How long does flux take to dry?
Syringes require approximately fifteen minutes while jars and cartridges can take up to 45 minutes. DO NOT heat paste with an oven or other environment set above “room temperature.” Dry all packing completely prior to use to prevent water coming in contact with the solder paste.
How long is flux good for?
For brazing flux the stated unopened shelf life is typically 1 year.
Can you eat flux through copper?
Competent plumbers are careful to avoid getting flux inside the pipes when soldering the fittings. When flux residue coats the interior surfaces of copper pipes, corrosion can gradually work through the pipes, resulting in pinhole leaks. In hot water pipes, the flux usually dissolves and washes away.
What solder is best for electronics?
6 Best Solder for Electronics Reviews Kester Solder. First on our list is the Kester Solder, a 0.031 inches diameter steel-based solder with very high conductivity. Maiyum Solder Wire. SONEAK 60/40 Tin Lead Solder. Austor Solder Wire. Canfield Solder. Mandala Crafts Store Rosin Core Solder Wire.
What kind of soldering iron do I need for electronics?
For basic non-temperature controlled irons, a wattage of 40 watts may be good for general work, and higher if heavy soldering is envisaged. For small PCB work, 15 or 25 watts is a good value.
Why is my soldering iron not hot enough?
If your soldering iron isn’t producing any heat, it is likely because of a break in the electrical circuit, resulting from either a faulty connection in the iron or heating element failure. If all electrical connections were good but you registered no continuity, your heating element will need to be replaced.
