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.

What is the purpose of flux in the soldering process?

Soldering usually applies to electronics, but can be used in many different applications. Soldering in electronics is done by melting solder (in this case, a small hollow wire made up of 40 percent lead and 60 percent tin), which contains rosin (flux) in the hollow core. The purpose is to secure the electronic parts to the circuit board. Desoldering is a removal of the solder already used, to release the parts from the circuit board so that a replacement part can be installed and soldered into place again. I do it all the time as a matter of course and I can tell you first hand, it's not rocket science. Knowing the difference between a good solder connection and a bad connection when you're through isn't hard, but most hobbyists usually don't pay that much attention to the quality of the joint.


If you cut the wires from the wire harness in a 1990 f150 what do you do to fix it?

what wires are they? If they are just regular wires like for lights or something, the best method is to solder them back together with rosin core solder and cover them with heat shrink tubing what wires are they?

How do you fix a airsoft battery wire?

Solder the wire.


Why Wire cannot be drawn from wood?

Wires may only be drawn from ductile (malleable) materials. By the definition of wire, it must be of metal, though some solder wires contain a core of rosin.


What is soldering wire?

Solder is a group of metallic alloys that melts at a relatively low temperature and is generally used to connect other pieces of metal together. The low melting point makes it useful for some applications, especially electronic circuitry and some plumbing applications, though it should be noted that plumbing solder is a different alloy than electronic solder and plumbing solder has little or no lead to minimize lead exposure to the people who drink the water. Having described what solder IS, soldering wire is just that, its a wire that is made of solder. Solder wire is useful when working on electronic circuits since it allows the user to control how much will be put on an electronic connection. Solder wire comes in several sizes, as well as with or without a flux core. Flux is a material (usually either acidic or rosin) that encourages melted solder to flow onto other metals, usually copper, iron or brass. Other types of solder are available for use on materials such as aluminum, but solders should match the application to match the type of metals you are joining.


Is solder wire insulator?

Solder will conduct electricity, so is not an insulator.


What is meant by tinning stranded wires?

It is a reference for the preparation for soldering a stranded wire so you get a good joint. You twist the strands together, heat the wire with a soldering iron or gun and then apply a small amount of solder on the tip of the wire and it melts into the strands. Then you can solder the wire to another like wire or to a terminal or whatever. You basically reheat the wire to make connection and can add more solder as needed.Additional informationTinning is also useful if the wire is to be put in a "screw lug". The term "tinning" comes from the fact that older solder contains lead and tin. Some of the newer solder is supposed to be lead free.


Why do you need to tin first the wire before soldering it?

pre tinning make it easier to solder wire because the solder is already " stuck" to the wire. and less solder will be needed to join the wire. if you watch the solder under a magnifier while tinning, you will notice the solder does not flow and "stick" until proper heat and flux ar applied. this heat usually is more than required to melt the solder because it takes mor heat to heat up the wire due to higher density. after tinning, less heat is required to melt the solder, and enough flux is usually left from tinning to quickly join the wire to the desired material provided the material is also tinned. this reduces cold solder and provides for a more relible connection. To tin the wire first is to cover the end of the wire with a layer of solder before you put it thru the hole in the PCB that will give you insurance of a proper electrical contact else you will put a heap of solder on the PCB without a proper contact with the wire itself what is called a dry joint that go for un tinted copper wire only normally all electronic component pins is factory tinted


Preparing the wire by coating it with solder is called?

Tinning


Explain how to apply tinning technique in soldering?

Strip the wire to desired length. Then hold the wire horizontally and hold the soldering iron underneath the stripped part while holding the solder on the top of the wire. When the wire gets hot enough it will suck the solder into the wire


When you preparing a wire by coating it with solder what is it called?

It is known as tinning.


Can lead be turned into wire?

Very easily. A wire form of an lead-tin alloy is often found as wire solder.
