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. Непрерывный пустой горящий обычный электрический пайка утюг воля причина окисление пайка железо наконечник и аффект сервис жизнь.
2. Непрерывный пустой горящий, ты будет найдете что the 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 пайка железо.
4. The constant temperature пайка утюг can be powered on all the time, because the temperature will not be too high.
Что есть нормальный температура из пайка утюг
When the electric пайка утюг is пайка different things, the temperature is different, and the temperature is different when пайка медь и пайка железо, depending on the actual situation. Generally, it is между 350 градусы и 400 градусы, as long as as it is выше чем 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 число также определяет его температура:
220V
20W 400 degree
25 Вт 450 градус
30W 500 degree
40 Вт 530 градус
50W 580 degree
60 Вт 600 градус
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 while the soldering process, such as false soldering, short circuit or even solderal solder of the circuit board. Следовательно, it is required to use a a high-end пайка утюг as much as possible, such as as a constant temperature and anti-static solder iron. В дополнение, некоторые большие компоненты такие как экранирование крышки нужно к использование высокая мощность электрика пайка утюги, so an обычный 60W or more толстый наконечник электрический пайка утюг должен быть подготовлен.
