To facilitate the soldering process, a chemical material called flux can be used to remove oxidation from the surface, keep the air from oxidizing the surfaces during soldering, and to aid in the flow of solder through the joint. Fluxes can be found within the solder (cored solder) or separately in paste form.

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.

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.

Solder has traditionally been a tin lead alloy, but there are many variations depending on the application:
- jeweler's solder or silver solder, has always contained silver to prevent the solder from dissolving silver and/or gold from the item being soldered
- other low melting point metals are sometimes added to make low melting point solder
- pure tin solder is sometimes used to eliminate toxic lead
- etc.
Solder sold in the form of wire is sometimes hollow with a core filled with flux paste to make soldering easier without the need for extensive precleaning of the work so that the solder properly wets. For plumbing purposes (where the work can be rinsed afterwords) the flux paste is acidic and very corrosive, for electronics work the flux paste is a rosin.

Clean the two pieces of pipe with emery paper or a pipe cleaning wire brush. put a little solder paste on male pipe and insert in connector. Heat the connection for several inches in both direction to warm up the pipe then concentrate the torch a quarter inch below and around the joint on the female end and the braising rod. Touch the rod to the joint. When the temperature of the pipe is hot enough the rod will melt and flow or be sucked sucked towards the heat. Move the rod all around the joint. LOL Actually, while most of the above information is true, I wouldn't recommend using solder paste or any type of flux when you braise refrigerant lines. You don't want anything besides R-22 (freon) or R 410-A (puron) in the lines and solder paste could mess up the compressor. Your should only use solder paste or flux when soldering!

Tin can be extracted from solder by heating the solder paste to a temperature above the melting point of tin (232°C) but below the melting point of other metals in the solder blend. This process allows the tin to melt and separate from the other metals, which can then be removed through physical separation methods.

- Cold solder joint: occurs when the joint doesn't fully melt, leading to poor electrical conductivity.
- Insufficient solder: not enough solder used, resulting in weak or incomplete bonds.
- Excessive solder: too much solder applied, causing bridging or short circuits.
- Solder balling: result of excess solder that forms into small balls.
- Solder splashes: occurs when excess solder splashes onto nearby components.
- Solder flux residue: leftover residue from flux can lead to corrosion or poor connections over time.

To remove solder flux stains from clothing, wipe off any excess of flux from the clothing with a piece of paper towel. Mix 1 tbsp. of baking soda with enough warm water to make a paste. Apply the baking soda paste to the flux using an old toothbrush. The baking soda will act as a neutralizing agent. Wipe away the baking soda and the dissolved flux from the clothing with a damp cloth, then let it air dry thoroughly.

A reel of solder used for joining electrical circuits together on circuit boards.
Solder is made of a mixture of tin and lead and sometimes has has flux (a form of acid) in the core of the solder to ensure a clean surface for the solder to flow into.

This is known as solder bridging, where an unintended connection forms between two conductive paths due to excess solder. It can cause short circuits and impact device functionality. Preventing solder bridging involves using the correct amount of solder and properly inspecting and cleaning the solder joints after soldering.

Depends on the solder used. If silver solder is used it is actually stronger than the pipe itself.

Removes solder from electronic components so that they can be removed from the circuit board

Solder has to be heated in order to melt it for removal, usually by a soldering iron. Then the removal methods can vary. You can get a braided solder remover from a local electronics store that when applied to the melted solder will "wick up" the melted solder.
Then there's the vacuum bulb or vacuum hand held solder pump that is used by placing it on the melted solder and either by releasing the bulb or tripping a lever, will literally suck the solder from the connection.
Soldering is easy to learn but there are pitfalls if you're not familiar with the techniques, proper sizes of soldering irons, etc.

Solder typically melts at temperatures between 180°C to 190°C (360°F to 375°F), depending on the type of solder alloy being used.

The compound symbol for solder can vary depending on the specific composition. Common solder compounds include tin-lead solder (Sn-Pb) and lead-free solder such as tin-silver-copper (Sn-Ag-Cu) or tin-copper (Sn-Cu).

A Conductor, SOLDER IS NOT AN INSULATOR. The most common types of solder are made of tin and lead. Another type is silver solder. All of the materials used are metals and are good conductors of both heat and electricity.
If you solder something you would notice if you ever held a wire (without protection) while applying solder to it your finger would probably receive a burn (speaking from experience).

Silver jewelry requires that you use silver solder for repairs. It is silver based where common solder is lead or tin based. Standard solder is too acidic and will corrode the jewelry. It can probably be found on e-bay. Or ask a jeweler where he or she gets it.

"Solder" can be a noun or a verb. The following sentences provide examples of both:

It could be either. Any type of liquid core solder (acid core, rosin core, etc.) is heterogenous, since there's the metal part and the core part.
A solid-core solder is probably homogeneous.
