If you let the solder sit on the iron, the flux quickly boils off (the fumes are from flux, not the lead). And without flux, soldering becomes almost impossible. Flux removes oxidation from metals, and it’s crucial because solder won’t stick to oxidized metals, and metals oxidize very quickly at soldering temperatures.
Why is my solder not working?
Heat is the number one reason that solder flows. Without it, you’ll unsuccessfully try to solder a piece for a very long time. Heat is a tricky thing to figure out, especially if you’re just starting out.
Why does solder not stick to my iron?
It is possible you are attempting to melt solder that is a higher temperature grade than your iron is capable of melting. ( I had this problem once ) check it out. A typical iron is 50W you may need 150 or higher. A 50W iron can be used with HMP solder.
How do you get solder to stick to surface?
Common Soldering Mistakes | Soldering – YouTube
Why is my solder turning into a ball?
Solder balls are caused by gassing and spitting of the flux on the surface of the wave or by solder literally bouncing back from the solder wave. This is caused by excessive back flow in air or too high a drop in nitrogen environments.
What temperature should I solder wire?
How do I 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 will my solder not flow?
Overheating destroys the solder’s make-up by burning it, this makes it impossible to flow at all even when the right temperature is eventually reached. Even if the heat is distributed evenly, but the solder balling up and still not flowing, stop and remove the flame from the piece; the solder is most likely burnt.
Can I solder without flux?
Yes, you need flux. Solder wire usually has flux in its core, but most still apply additional flux. I would figure out what specification of flux is in the solder wire you’re using and buy that type. To obtain the best results, always use extra flux!
Will solder stick to any metal?
You should solder most flat metals, such as copper and tin, with a rosin-core solder. Use acid-core solder only on galvanized iron and other hard-to-solder metals.
What will you do if the solder lead does not stick to the soldering tip during the tinning process?
Solder NOT sticking to the Tip , how to Clean and re tin
How can I get better at soldering?
Thus the following are some essential tips to improve your soldering skills.
- Use Suitable Equipment. Generally, it is very important for you to have or purchase the right and correct solder type and width.
- Use Good Equipment.
- Clean Equipment.
- Read Up.
- Applying Solder.
- Recognize The Mistakes.
- Solder Quickly.
What do you do if solder won’t melt?
This may happen if heat is being conducted away by a copper layer in the board, acting as a big heat sink. One thing that may help is to melt fresh solder between the iron and the joint to act as a bridge and ensure good heat conduction. You might also try a high power soldering gun instead of an electronics iron.
Can Vaseline be used as flux?
Petroleum jelly is one of the best flux alternatives you can use. It is equally as effective as commercial flux, costs about half the price, and most people already have it on hand.

How to Clean and Re-Tin your Soldering Iron
How do you prevent soldering balls?
Ways to prevent solder balls from being created
- Make sure the PCB boards are not stored in humid environments.
- Ensure that the board is properly dried or preheated (to evaporate trace water amounts) before printing.
- Clean the printing stencil properly before application of solder paste.
Why is my flux burning?
Don’t overheat the flux
If you don’t heat the joint enough, the solder won’t flow into it. If you heat the joint too long, you’ll burn the flux (it’ll smoke and turn black) and make it difficult to get the solder to flow into the joint.
What is solder splash?
Solder splashes during waver soldering are often caused by the application of excessive flux, and/or inadequate preheat. The volatile materials used in fluxes, typically solvents, will explosively vaporize upon contact with the solder wave. This causes solder splashes.
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.
Why do we need to use damp sponge during soldering?
The purpose of the sponge is as follows; the sponge is porous, so it holds water. Rubbing a hot soldering iron tip on a wet sponge causes the solder to contract at a different rate than the soldering iron, helping to knock off any globs of solder that may be clinging to the tip.
At what temp does solder melt?
Soft solder typically has a melting point range of 90 to 450 °C (190 to 840 °F; 360 to 720 K), and is commonly used in electronics, plumbing, and sheet metal work. Alloys that melt between 180 and 190 °C (360 and 370 °F; 450 and 460 K) are the most commonly used.
What is flux for soldering?
What is Flux? Flux aids in soldering and desoldering processes by removing oxide films which form on the surface of metals being soldered. It increases the wetting ability of the solder, causing it to flow more uniformly over surfaces without balling-up (dewetting).
How do you make homemade solder flux?
How To Make Your Own Flux
How do you know if solder has flux?
Does Your Core Solder Have Enough Flux?
Can you solder with a lighter?
You can use anything that is able to heat a piece of metal up to the melting point of your solder (between 400°F / 200°C and 700°F / 370°C). Butane lighters work the best. But you can also use candles, oil lamps, alcohol burners, or even open camp fires.

How to Solder, tips and tricks
What metals will solder not stick to?
Solder will not stick to just any metal. For example you will never get solder to stick to Aluminum. With compatible metals, however, you must use a suitable flux after preparing the metal surface to remove any oxidation. The flux will prevent new oxidation from forming when you heat the metal.
