Flux helps promote soldering. Soldering paste might contain flux and other items to help promote soldering. The paste helps hold the flux in place while beginning to solder.

What is the difference between reflow soldering and wave soldering regarding lead free alloys recommended by NEMI?
In reflow soldering, the solder is applied as a 'solder paste' typically by using a stencil mask and a squeege. The solder paste contains both a solder flux and the solder in the form of minute solder balls. The solder paste operation is done BEFOREadding the components to the board. The board is then passed through a reflow oven at which time, the solder paste melts to complete the soldering of the components to the circuit board. The reflow oven will have several heating zones designed to preheat, activate the flux, reflow the solder, and cool the board. The oven is setup so the components receive as little thermal shock as possible, and spend only a few seconds above the solder melting temperature.In wave soldering, the components are placed on the board. THEN the board is placed in the wave soldering machine. Typically the first step in the wave solder, the bottom of the board passes through a fluxing operation which either sprays flux on the bottom or passes the bottom of the board through a flux foam. After the flux, the board will usually pass a pre-heater to activite the flux and pre-heat the board for the soldering. Then, the bottom of the board is passed through a molten solder wave (looks like a smooth waterfall only consisting of molten solder). Afterwards, there will be a stage of cool-down.Some details of the process vary by how expensive the oven or wave-solder machine is, the complexity of the circuit board involved, for what kind of volume the production line is intended for, and how 'mil or space qualified' the circuit board is.
What is the difference between infinite electric flux and finite electric flux?
the difference between lightning and a single cell battery
Your car heater on back has come unstuck how do you fix it so it will clear again the solder has come off?
You can use a paste flux and heat (as from a soldering gun) to reattach the solder.

What is flux and in which operation is it used?
Flux is used to prevent oxidation while soldering wires and components in electronics.
When soldering what should the flux be applied to?
The materials being soldered.
Why won't your soldering work?
A: The pad is not clean it has tarnish or wrong solder with not enough soldering flux. Finally not enough heat.
What is the purpose of flux and state the importance of cleanliness of metals when soldering.?
Gd
What is the purpose of a flux and state the importance of cleanliness of metals when soldering?
Gd
What is flux used for when soldering?
Flux is used to keep metals from oxidizing. Solder will not bond well with copper-oxides which are formed when copper is exposed to high temperatures (ie a soldering iron) the flux prevents the oxidation. If you were to solder without flux the solder joint would be weak and possibly completely nonconductive.
How will you define flux?
A state of continuous movement or a medium used in metal soldering.
What tools are needed to solder circuit boards?
Soldering iron, solder, flux
