Why is the iron tip of the 10 yuan electric soldering iron I bought black and oxidized soon Others w

There are two reasons for this, 1. The quality of the soldering iron tip is different, the ordinary red copper is easy to oxidize, and the constant temperature soldering iron uses an alloy head. 2: Due to temperature, metals are easy to oxidize at high temperatures, including soldering iron tips.

The constant temperature can be kept in a usable but not over-temperature temperature range, and the surface of 10 yuan will definitely not be able to do.

The temperature of your soldering iron must be very unstable, it may be very high and the temperature is high, the soldering iron tip will be oxidized, you can buy a thermostatic soldering station. The actual measurement temperature and set temperature of the soldering iron tip of the constant temperature soldering station are within + -10 degrees, and your 10 yuan soldering iron has no temperature control, and the actual temperature may be 500 degrees if you set 300 degrees!

The oxidation and blackening of the soldering iron tip is one of the more common problems in electronic soldering, and the different quality is one of the reasons. Usually, the oxidation and blackening of the soldering iron tip is a mistake in operation and maintenance. A ten-dollar soldering iron is still okay as long as it's not bought in a retail store.

Soldering iron tip oxidation treatment method:

1. Adjust the temperature to 300 first, clean the soldering tip with a cleaning sponge, and test the condition of the soldering nozzle.

2. If the tin plating part of the soldering iron tip contains black oxide, you can coat the new tin layer, and then wipe the soldering iron nozzle with a cleaning sponge. This is repeated until the oxide is completely removed, and then a new tin layer is applied.

3. If the soldering iron tip is deformed or perforated, the soldering iron tip should be replaced.

Note: Do not use a file to remove oxides from the solder nozzle.

When the soldering station is not in use, do not let the soldering tip be in a high temperature state for a long time, which will convert the flux on the soldering tip into oxide, that is, the oxidation of the soldering iron tip, resulting in a great reduction in the thermal conductivity of the soldering iron tip. When the soldering station is not in use, the power should be turned off (for soldering stations that are not temperature controlled and have no automatic sleep function).

Hello! Well, you're idle in the store, aren't you?

Why is the iron tip of the 10 yuan electric soldering iron I bought black and oxidized soon Others will not be like this

The problem of price, the problem of design, the problem of quality, the problem of different metals used in the iron tip of the soldering iron.

Of course, the constant temperature is more expensive, and if the ordinary use does not need to be opened, you will buy a constant temperature and put it at home=. =“

When in doubt, please ask.

It is necessary to feed the soldering iron tip with solder first, and then use rosin as flux when soldering, so that it is not easy to burn to death! (Oxidation) first use sandpaper to polish off the oxide on the soldering iron head to make the copper head smooth, and then put some broken rosin and small solder particles on a piece of sandpaper! After the soldering iron is plugged in and heated, wipe it with rosin on the sandpaper, melt the solder grains, and the soldering iron tip will be full of solder after a while!

Feed alive. 1.The temperature of the electric soldering iron is too high during soldering, which is easy to cause rapid oxidation of the soldering iron tip.

2.After soldering, the soldering iron tip was not tin in time.

3.The quality factor of the soldering iron tip itself.

4.The flux used is highly corrosive, which causes rapid oxidation of the soldering iron tip;

5.If the tip is exposed to high temperatures for a long time, it is easy to produce intermetallic compounds of tin and iron, and the tip oxidizes rapidly. If the soldering iron is not used for more than ten minutes, please turn off the power in time.

6.If the solder tip is stained with carbide flux, the solder tip will not be able to melt the tin to send enough heat to the solder joint, because the solder tip must transfer heat through the molten tin as a medium, and the iron plating layer of the solder tip will be exposed and oxidized due to the lack of tin melting.

The reason for the oxidation of the electric soldering iron is that the user does not maintain the soldering iron tip, how to deal with the oxidized black soldering iron tip, first use a knife to scrape off the black layer on the soldering iron head, until the natural color of the copper is scraped yellow, and then add rosin solder. Remember to fill the front with solder when not using the soldering iron, which is called maintenance of the soldering iron tip. There will be no oxidative blackening. As shown in the figure below.

Why is the tip of the soldering iron black? What should I do if the soldering iron tip is oxidized and blackened? A simple deal can be solved, like DIY friends, please remember to pay attention, if you think**is helpful to you, please like, favorite, comment**, support.

Treatment method for frequent oxidation of electric soldering iron tips:

Put it in the rosin and coat it with solder, roll in it, and the oxide will fall off after a while, and after the usual use, fill the head with tin until it can't stick, and wipe it on the wet sponge next time you use it.

If the soldering iron tip is burned to death (a black layer, no tin, or only a tin ball is melted), scrape the head with a blade to expose the copper part, scrape it quickly, don't use too much force, and melt the solder wire on it immediately after scraping, but in the long run, the life of the soldering iron tip will become shorter, and if you do not use it for a long time (more than 20 minutes), try to turn off the power to extend the life of the soldering iron tip.

Tin wire DXT-N5 for electric soldering iron Please use the soldering iron tip correctly, store it properly after each use, clean the soldering iron tip first, and apply an antioxidant coating on the soldering iron tip for better use next time.

In fact, there is a simple way, use sandpaper to slightly polish the oxidized soldering iron tip, grind off the oxide layer, and then tightly wrap the solder wire around the soldering iron tip, and then plug in the electricity to heat it to see if it can be hung with tin, which is how I repaired it.

It's all like this, and the Japanese original is better. Pay attention to the temperature not to be too high when using, often use a high-temperature sponge to wipe it, keep the soldering iron tip always have tin, and put a little tin on it when the power is off and off.

Not using tin is basically oxidation.

To improve the life of the soldering iron tip, the basis is the correct use and maintenance method, I only emphasize one point, after the use of the soldering iron tip tin maintenance, the soldering iron should not be directly scalded flux.

On this basis, extending the life of the nozzle is to process low-temperature soldering, lead-free soldering 350 degrees is more than double the life of 400 degrees, and every 10 degrees of reduction will bring exponential growth in consumables life and yield gains.

Low-temperature soldering also involves the quality of the soldering station, preheating, soldering, and the selection of a bunch of technologies, all of which are the main ones that spend money.

It is best not to use a blade or sandpaper to sand, as this will cause the original coating of the soldering iron tip to lose its original oxidation resistance. The best way is to use a special sponge to absorb water and dip it, and let the soldering iron eat more solder when you use it for the first time.

Copper or iron will produce an oxide layer after heating, so it will turn black Treatment method Use a sponge to absorb water, dip the soldering iron tip on it, and the oxide layer will fall off, and the light will be as bright as ever.

Why is it dark:

The iron plating layer of the soldering iron tip is thick, and the power of the soldering iron itself is not enough. This results in the formation of a layer of appendages on the surface of the soldering iron tip, as well as what we often call carbides or oxides.

How to solve: Use a blade or sandpaper to grind off the surface appendages, adjust the temperature to the highest state, and let the tinning of the soldering iron tip be tin as soon as possible.

Problem avoidance: It is best to respond to the problem to the soldering iron tip dealer to solve the root cause.

The high temperature causes the surface of the metal to oxidize, resulting in a black color.

Usually, the soldering iron is the main body of the seat such as iron and copper, and the nickel plating is carried out at the soldering head, which is to prevent oxidation, and secondly, it can be better stained with tin and facilitate soldering.

When the soldering iron is used for a long time, or if it is not properly maintained, the nickel plating layer from the soldering head will be removed, and in serious cases, it will even corrode off, exposing the iron and copper body underneath, which is black after oxidation. At this time, it is difficult to re-apply tin to the soldering iron tip, resulting in difficulty in soldering. Therefore, after each soldering, add an extra layer of tin to the tin on the soldering iron head to prevent the soldering iron from coming into contact with the air, thereby preventing oxidation.

After high temperature, the surface is carbonized and wiped with sandpaper.

The soldering iron is subjected to high temperatures, and it is not processed from time to time after soldering.

1.The blackening is mainly due to the oxidation blackening of the surface of the solder nozzle because there is no protection, and the blackening layer is generally oxide, so it is not tinned.

2.The most basic maintenance of using the soldering iron is to ensure that there is solder on the surface of the solder nozzle at all times, so that the customer ensures that the solder nozzle is not oxidized, and the next time it is used, it can be wiped clean immediately and used directly, and there will be no tin on it.

3.As long as the sponge is not the kind of wine in the soup, the standard is to squeeze until there is no water, and the water in the space below is provided with capillary action, but the average person is lazy, so it is okay to ensure that it is wet.

4.The temperature of the soldering iron is generally adjusted to about 380, which is generally the general temperature, and too high can not actually improve the efficiency but is easy to blacken.

5.Maintenance skills first ensure that there is solder, the rest is dispensable, but it is relatively improved, but there is a set of systems to do, this point of play I must not be able to lift up, so it is omitted, first do it every time there is solder, and then wipe it clean before use.

Blackening of the soldering iron tip after a long time is a common oxidation phenomenon, there are the following ways to solve this problem, 1. File the black oxidized part with a file when the power is not on, and re-dip it in rosin and tin after the power is on.

2. Put some rosin and solder on the sandpaper, and rub the soldering iron repeatedly in the rosin and solder sandpaper after heating it until it is bright. In order to solve the problem of black hair of the soldering iron, you can make a small solder cylinder (can be made of small metal cans, bottle caps, etc.), and usually immerse the soldering iron tip in the soldering cylinder to prevent the soldering iron tip from contacting with the air.

1. File and sandpaper.

If you buy a soldering iron set, you will have a file, and if you don't have a file, you can find a sandpaper. To output the oxidized blackened soldering iron, polish the soldering iron tip with a file or sandpaper until all the black oxide is removed. When the power is applied again, the soldering iron tip can stick the solder normally.

2. Alcohol. We don't use 75% of the medical alcohol that we have at home, we need to use more than 90% of the alcohol here. Because most of the soldering iron tips are still made of copper, the oxidized and blackened is the copper oxide generated by copper and air, copper oxide is different from copper, it is non-stick solder. When the soldering iron is not heated, insert the soldering iron tip into 90% alcohol, turn on the soldering iron, and wait for about 2 minutes to take it out to use normally.

3. Change the soldering iron tip.

In this case, you can also consider using it, and directly replace the soldering iron tip with a new one, which is relatively easy.

Extended Information: Use and Maintenance of Soldering Irons:

A new soldering iron cannot be used immediately, and the soldering iron must be treated before it can be used normally, that is, the soldering iron tip should be coated with a layer of solder before use.

Adjustment of the length of the soldering iron: After selecting the power of the electric soldering iron, the length of the soldering iron tip inserted into the soldering iron core can be appropriately adjusted according to the specific situation, so as to control the temperature of the soldering iron tip.

There are two types of soldering irons: straight and elbow, and when the pen grip method is used, the electric soldering iron with straight soldering tip is more flexible to use. It is suitable for soldering in circuits with many components. The positive grip method is more suitable for the soldering iron with the bent soldering iron tip, which is mostly used for soldering in the case of the vertical desktop of the circuit board.

The electric soldering iron is not easy to be energized for a long time without use, because it is easy to accelerate the oxidation of the electric soldering iron core and burn off, and at the same time, it will also make the soldering iron tip oxidize due to long-term heating, and even be burned "to death" and no longer "eat tin".

The soldering iron turns black because after soldering, oxidation occurs, you can use the Qinghao agent for a minute or two, and clean it immediately after each use.

You must first feed the soldering iron tip with solder! Use rosin as flux when soldering in the future! It's not easy to burn to death again! (oxidation).

First, use sandpaper to polish off the oxide on the soldering iron tip! Make the copper head clean! Put some crushed rosin and small solder particles on a piece of sandpaper!

After the soldering iron is plugged in and heated, wipe it with rosin on the sandpaper and melt the solder grains! After a while, the soldering iron tip will be full of solder!

Copper or iron will produce an oxide layer after heating, so it will turn black Treatment method Use a sponge to absorb water, dip the soldering iron tip on it, and the oxide layer will fall off, and the light will be as bright as ever.

Use sandpaper to sand, in fact, you don't have to worry about it and it's not dirty, just stick to it, the temperature is high, and it will be black next time you use it, do you think it's okay?

Normal, don't mind too much, the soldering iron is a consumable part and can be replaced.

Not used with rosin!

1. The soldering iron tip will oxidize at high temperature, so it will turn black. To reduce blackening, it is necessary to lower the temperature appropriately when in use, or when idle.

2. The early soldering iron tips are pure copper, and the oxidation products of pure copper in the atmospheric environment of about 200 degrees Celsius are gray-black.

Now the soldering iron tip no longer uses a single copper, and the surface of the copper is coated with a layer of Cr, nickel or other resistance to lower temperature oxidation, which has good wettability with solder.
