1. Pen-shaped soldering iron
This kind of electric soldering iron is generally a pointed tip, and there are two types of adjustable temperature and non-adjustable temperature.
Its characteristics are: low price, suitable for soldering of plug-in components, non-adjustable pen-shaped electric soldering iron, oxidized with long-term high temperature, and the tip of the tip is no longer tinned.
For the LQFP package TSSOP package, the pointed electric soldering iron is generally not easy to use, and it cannot be replaced with a knife-edge soldering iron tip, which has great limitations.
It is only the soldering of plug-in components. For some simple soldering needs, you can use a harmful electric soldering iron.
2. Tip electric soldering iron
Welding stations are generally temperature-adjustable, and some are also equipped with heat guns. The original one has a pointed tip, but due to structural compatibility, it can be replaced with a knife-edge soldering iron tip.
When using a pointed electric soldering iron, the welding temperature of general electronic components can be adjusted to about 350. When there is a fan heat design on the PCBA, the temperature can be appropriately adjusted to ensure that the temperature can melt the tin on the PCBA.
Because the knife edge of the knife-edge soldering iron head can be effectively attached to the pins of the SOP/TSSOP/LQFP package, it will be easier to handle when removing tin.
