Classification and structure of electric soldering iron
1. External heating electric soldering iron
It consists of a soldering iron tip, a soldering iron core, a shell, a wooden handle, a power lead, a plug, etc. The soldering iron tip is installed inside the soldering iron core, so it is called an external heating type electric soldering iron.
2. Internal heating electric soldering iron
It is composed of handle, connecting rod, spring clip, soldering iron core, soldering iron tip, etc. Because the soldering iron core is installed inside the soldering iron head, it generates heat quickly and has a high heat utilization rate, so it is called an internal heating type electric soldering iron.
3. Tin-absorbing soldering iron
Tin-absorbing electric soldering iron is a desoldering tool that integrates piston-type tin suction device and electric soldering iron. It has the advantages of convenient use, flexibility, wide application range, etc., but the disadvantage is that only one solder spot can be desoldered at a time.
4. Constant temperature electric soldering iron
The constant temperature electric soldering iron is equipped with a temperature controller with a magnet in the soldering iron head of the constant temperature electric soldering iron, and the temperature control is realized by controlling the power-on time. It is used for components whose soldering temperature should not be too high and soldering time should not be too long.
5. Heat gun
The hot air gun is also called the SMD electronic component desoldering station. It is specially used for soldering and dismounting of surface mount electronic components (especially multi-pin SMD integrated circuits).
