How to use solder wire correctly for efficient soldering?

Before using the solder wire, the soldering iron tip should be brightened with fine sandpaper, heated with electricity, dipped in rosin, and then touched with the edge surface of the solder wire tip to make the solder wire head evenly plated with a layer of tin. In doing so, it can facilitate soldering and prevent oxidation of the surface of the solder wire head. If the old soldering iron tip is severely oxidized and blackened, the surface oxide can be frustrated with steel to expose the metallic luster, and then re-tinned before it can be used.

The soldering iron should use 220V AC power supply, and special attention should be paid to safety when using it. The following points should be carefully achieved: the three-pole plug is best used for the electric soldering iron plug.

Make the enclosure properly grounded. Before use, the power plug and power cord should be carefully checked for damage. And check if the soldering iron tip is loose.

When using an electric soldering iron, do not strike it too hard.

To prevent falls. When there is too much solder on the soldering iron tip, it can be wiped off with a cloth. Do not throw it indiscriminately to prevent burning others.

During the soldering process, the soldering iron should not be left around. When not soldering, it should be placed on a soldering iron holder. Note that the power cord should not be placed on the soldering iron tip to prevent accidents from burning the insulation.

After use, the power should be cut off in time and the power plug should be unplugged. Once cooled, retract the soldering iron into the toolbox. Solder and flux are also required for soldering and flux soldering.

Soldering: Soldering electronic components, generally using solder wire with rosin core. This solder wire has a low melting point and contains rosin flux, which is extremely convenient to use.

Flux: A commonly used flux is rosin or rosin perfume (which dissolves rosin in alcohol). The use of flux can help remove oxides from the metal surface, facilitate soldering, and protect the tip of the iron.

Solder paste can also be used when soldering larger components or wires. But it has a certain corrosiveness, and the residue should be removed in time after welding.

First of all, when we use solder, we must first identify whether it is solder! If not, don't mess around! If you can't tell the difference, please see the experience (how to distinguish between solder wire and fuse)!

We need to warm up the soldering iron first! When warming up, we need to put the soldering iron on a secure stand! Don't leave it indiscriminately, once accidentally put on the wire, it will cause electric shock and cause fire!

Secondly, before we use solder, we must dimmer the soldering iron tip in rosin! Put the hot soldering iron tip in the rosin and quickly remove it! This step is to make the soldering iron tip better tin!

Then we put the soldering iron tip close to the place where the tin needs to be placed, and put the solder wire on the soldering iron tip! Melt the solder and cover the area where the tin needs to be placed, and quickly remove the solder wire! At the same time, after a second or two, after the solder has completely melted and become shiny, take the soldering iron away!

If the device that needs to be soldered is not resistant to high temperatures, please pay attention to the time of tin loading yourself! Avoid burning out the device! We can also attach the solder directly to the soldering iron tip, and then use the soldering iron tip directly to the position where we need to solder!

After soldering, pay attention to clean the solder head, otherwise the next use of the preheating time will be slow, and it is not easy to tin at the same time! Unplug the soldering iron and put it away!

In the process of soldering, the soldering iron tip is in a high temperature state for a long time, and the contact with flux and other substances that are decomposed by heat will easily oxidize the surface of the soldering iron tip to form a layer of black impurities, so that the soldering iron tip loses the heating effect, so Tongfang solder wire reminds the operator to pay attention to the cleaning of the soldering iron tip. Regarding the use of flux, Tongfang solder wire reminds operators to pay attention to the fact that the use of flux needs to be appropriate, and if it is excessive, it will prolong the heating time, reduce the work efficiency, and easily form the phenomenon of slag inclusion. If you use rosin core solder wire, you don't need to use flux.

Weldment surface treatment, manual welding process, all kinds of electronic parts or wires used often need to be cleaned before welding, so as to remove the rust, oil, dust and other effects on the welding process on the surface of the weldment, generally speaking, the method of mechanical scraping and alcohol wiping is used. In the pre-welding process, the welding part of the weldment should be wetted, that is, the surface of the weldment should be moistened with solder, and the surface of the weldment should be tinned after the bonding layer is formed by the diffusion of the metal, which makes the pretreatment process. The method of wiping with mechanical scraping and alcohol.

The solder wire DXT-V8 first preheats the soldering iron tip, and the product can be soldered on the molten tin.

Before soldering, the circuit board and wires should be cleaned, and the oil, paint and other dirt should be cleaned, and alcohol should be used if necessary. After cleaning, use an electric soldering iron to warm the solder joints, add rosin or solder paste, and use an electric soldering iron to tin the solder joints separately (that is, let the solder points hang on the tin first). Two or more solder joints are joined together using an electric soldering iron tin.

When the tin is melted, the soldering iron tip is used to directly touch the solder wire, and the solder wire melts when the temperature of the soldering iron reaches the melting temperature.

If the soldering metal is too large and the soldering iron cannot heat the temperature of the soldered metal to the melting temperature of the solder, the wattage of the soldering iron should be increased.

Hello! We are a double Chilean solder wire manufacturer! Here first of all, I will tell you what solder wire is and the role of solder wire.

What is solder wire? As the name suggests, solder wire is a tin wire used for soldering, and the tin wire indicates that its composition must contain tin. Generally, the metal composition of tin wire includes tin, lead, silver, copper, bismuth, antimony and other metal components.

Among them, tin-silver-copper, tin-copper, tin-lead solder wire is the main one, and these kinds of solder wire are mostly seen on the market.

The function of solder wire is for soldering, and it is generally used for soldering electronic components, such as the welding of capacitors, ICs, resistors and other components of circuit boards. Some special solder wires can also be welded to stainless steel, so we won't repeat them.

Based on the above description, it is not difficult to conclude that the place where solder wire is used is in electronics factories or electrical repair shops. If you still don't understand, you can ask us to understand.

The solder wire used in the soldering of manual electronic components is composed of two parts: tin alloy and additives, in electronic soldering, the solder wire is matched with the electric soldering iron, the high-quality electric soldering iron provides stable and continuous melting heat, the solder wire is added to the surface and gap of the electronic original device as a filler, and the fixed electronic original device becomes the main component of soldering, and the composition of the solder wire is inseparable from the quality of the solder wire, which will affect the chemical properties, mechanical properties and physical properties of the solder wire.

Solder wire without additives cannot be used for soldering electronic components, because it does not have wetting and expandability. The welding will produce spatter, the formation of solder joints is not good, and the performance of the additives for a long time will affect the performance of solder wire welding. The following are the uses of different kinds of solder wire.

Shizhen 1, rosin type.

It is suitable for electronic repair welding of electronic and related components, with high impedance of residue after welding, no leakage, and can pass the high-voltage test, which is the most commonly used slag return of tin wire macro in the electronics industry.

3) Electronic and communication equipment manufacturing: circuit substrate sintering, component tinning, component wave soldering, component manual soldering.

1. The function of solder wire is for soldering, which is generally used for welding electronic components, such as the welding of circuit boards, IC, resistors and other components. Some special solder wires can also be welded to stainless steel, so we won't repeat them.

2. According to the above description, it is not difficult for us to conclude that the application of solder wire is in the electronics factory or in the electrical maintenance shop. If you still don't understand, you can ask us to understand.

How to hold the solder wire in circuit board soldering.

Hello dear<>

In circuit board soldering, the steps to take the solder wire: 1Prepare the tool:

Solder wire, soldering iron, solder sucker, wire scissors. 2.Cut the solder wire into a suitable amount of length (usually 5-10cm) with wire scissors for easy use and control.

3.Wrap one end of the solder wire around the soldering iron, and control the twisting angle at about 45 degrees. 4.

When starting soldering, the solder head is perpendicular to the solder joint, and the other end of the solder wire is rented and prepared to push the solder wire to the other end of the solder head while the solder head is in contact with the solder joint. 5.Move the solder wire between the solder head and the solder joint.

Allow it to heat to the melting point and flow to the surface of the solder joint. 6.When the solder wire starts to flow, do not push the new solder wire and let it flow freely while keeping the solder tip on the solder joint until the solder wire is solidified and fixed on the solder joint.

7.After soldering, use a solder absorber to remove excess solder wire.

How to hold the solder wire in circuit board soldering.

Hello dear In circuit board soldering, the way to hold the solder wire is as follows: In the circuit board soldering, the way to hold the solder wire is very important, which is directly related to the quality and efficiency of soldering. The following royal mold wheel is some common solder wire holding methods:

1.Direct pick-up: Hold the solder wire directly in your hand for manual soldering.

This method is simple and convenient, but it requires the staking idea to control the length and temperature of the solder wire to prevent burns on the hands. 2.Bracket Take:

During the soldering process, the solder wire is placed on the bracket, and the stability and angle of the bracket are used to control the position of the solder wire to improve the welding accuracy and efficiency. 3.Pliers to take:

The use of pliers to grip the solder wire makes it easier to control the length and temperature of the solder wire and reduces the risk of burns to your hands. In short, in circuit board soldering, choosing the right solder wire holding method can improve the soldering accuracy and efficiency, and also protect hand safety. Different welding projects and welding methods need to choose the appropriate holding method to ensure the quality and safety of welding.

How beginners can quickly master the skills of soldering, I will introduce how to quickly get started Use the right tools: the temperature of the constant temperature soldering iron is constant, the soldering iron tip is not easy to oxidize, it is easy to apply tin, you can set the required temperature, and the bending cavity can be quickly used while the ordinary soldering iron temperature; The degree changes greatly, and the soldering iron tip is very easy to oxidize, which is difficult for novices.

Use solder wire with flux and don't use rosin, the smell of rosin will make you hate soldering.

Reasonable use of cleaning sponge, the cleaning sponge is first wet with water and then squeezed dry, and placed in the welding iron frame.

When you are ready, turn on the soldering iron, set the temperature, for example: degrees, and you are ready to solder. Put the soldering iron tip close to the place where the tin needs to be placed, and put the solder wire between the soldering iron and the pin!

Melt the solder and cover the area where the tin needs to be placed, and quickly remove the solder wire! At the same time, after a second or two, after the solder has completely melted and become shiny, the soldering iron is quickly removed at an angle!

When not soldering, put the soldering iron on the soldering iron rack at any time to avoid burning other things, pay attention to safety.

After soldering, pay attention to check the quality of the solder joints.
