What is the operating temperature of a soldering iron?
The temperature of the soldering iron is 300-400°C.
Specifically, when it is necessary to directly insert electronic materials, the temperature of the soldering iron tip should be set between 330-370 degrees. If it is a surface mount material, the temperature should be between 300-320 degrees. At a temperature of 290 degrees, the soldering temperature of large component feet cannot exceed 380 degrees. In addition, for special materials, special temperature settings are required.
The rear end of the internal heating type electric soldering iron is hollow, used to be sleeved on the connecting rod, and fixed with a spring clip. When the soldering iron tip needs to be replaced, the spring clip must be withdrawn first, and the front end of the soldering iron tip should be clamped with pliers. Pull it out slowly, remember not to use too much force, so as not to damage the connecting rod.
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 devices 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.
