How long the soldering iron continues to work will not damage the soldering iron.
Turn on the electricity and heat for about 3 minutes, the solder can be melted and it can work. The electric soldering iron cannot be fired empty, it can work continuously.
1. Continuous empty burning of ordinary electric soldering iron will cause oxidation of the soldering iron tip and affect the service life.
2. Continuous empty burning, you will find that the copper in the heating part of the soldering iron has been burned red, which will affect the life of the soldering iron.
3. Continuous work, such as welding all the time, this is not empty burning, and long-term work will not damage the soldering iron.
4. The constant temperature soldering iron can be powered on all the time, because the temperature will not be too high.
What is the normal temperature of the soldering iron
When the electric soldering iron is soldering different things, the temperature is different, and the temperature is different when soldering copper and soldering iron, depending on the actual situation. Generally, it is between 350 degrees and 400 degrees, as long as it is higher than the melting point of solder.
The highest temperature is generally 480 degrees Celsius, but it is generally ok to set it to about 320~400 degrees. If it is higher, the tip of the soldering iron is easy to oxidize.
The W number also determines its temperature:
220V
20W 400℃
25W 450℃
30W 500℃
40W 530°C
50W 580°C
60W 600℃
In the maintenance of mobile phones, the components on the circuit board are often replaced, requiring the use of a soldering iron, and the requirements for it are also high. This is because the components of the mobile phone adopt the surface mount process, the components are small in size, highly integrated, the printed circuit is fine, and the pad is small.
If the soldering iron is not selected properly, it is easy to cause human faults during the soldering process, such as false soldering, short circuit or even soldering of the circuit board. Therefore, it is necessary to use a high-end soldering iron as much as possible, such as a constant temperature and anti-static soldering iron. In addition, some large components such as shielding covers need to use high-power electric soldering irons, so an ordinary 60W or more thick-tip electric soldering iron should be prepared.
