Introduction to the characteristics of pen-shaped soldering iron and pointed soldering iron
1. Pen-shaped soldering iron
This kind of electric soldering iron is generally pointed, and there are two types: adjustable temperature and non-adjustable temperature.
Its characteristics are: cheap price, suitable for soldering 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 type of LQFP package and TSSOP package, the pointed 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. When performing some simple soldering needs, you can use a harmful electric soldering iron.
2. Pointed soldering iron
Welding stations are generally temperature-adjustable, and some are equipped with heat guns. The original one is pointed, but due to structural compatibility, it can be replaced with a knife-edged tip.
When using a pointed electric soldering iron, the temperature can be adjusted to about 350 for general electronic component soldering. When the PCBA has a fan-heating design, the temperature can be adjusted appropriately to ensure that the temperature can melt the tin on the PCBA.
Because the knife edge of the soldering iron tip can be effectively bonded to the pins of the SOP/TSSOP/LQFP package, it will be easier to handle during desoldering.
