Novices learning to solder circuit boards should buy the kind of soldering iron
First of all, if you are a student (PS: the one who can ask this question is also a student), don’t go to expensive ones for beginners. If you don’t like it, the sunk cost will be relatively high. It is not important to be able to adjust the temperature at first. Anyway, the welding of the hole board The plate will also fall off. The key is to buy a better soldering iron head. First of all, the quality is good. I have seen some people soldering and soldering the head half melted. Secondly, for beginners, if you just solder straight If the device, the hole board, etc., still consider the pointed head, the pointed head must be sharp enough. It is very important and will greatly affect your user experience. If you want to solder the patch later, it is recommended to use a knife-edge soldering iron tip, or use a hot blower for blowing and soldering and then press it again with a knife-edge soldering iron. At this time, the alcohol rosin solution is a sharp weapon. If it is BGA, then there is no way, go to the constant temperature soldering station.
