Što su the reasons zašto električno lemljenje željezo glave do ne jesti kositar
The quality of the electric soldering iron head direkt affects the zavarivanje kvaliteta. There are sever reasons why a general electric lemljenje željezo glava ne jede kositar.
1. Loša kvaliteta lemljenje željezo vrh
The previously commonly used inexpensive internal heating low-power electric soldering iron. The soldering head of this internally heated electric soldering iron is made of copper and cannot be adjusted for temperature due to the lack of constant temperature function. After being powered on for a period of time, the temperature of the soldering head will become higher and higher. At high temperatures, copper soldering heads are prone to oxidation and blackening. If the soldering head is polished with sandpaper or a file, it will still oxidize and blacken after a while. Therefore, if using the cheap soldering iron mentioned above causes the soldering head to oxidize and blacken and does not eat tin, it is recommended to replace the soldering iron. It is best to choose a constant temperature or adjustable temperature soldering iron.
936 podesiva temperatura električna lemljenje željezo specijalno lemljenje željezo vrh.
The lemljenje glava od 936 podesiv temperatura električno lemljenje željezo can be zamijenjeno i has višestruko oblici, which can be selected accord to zavarivanje potrebe. This type of soldering iron head is made of alloy Alloy Material and Is Not Easy oksidirano AT High Temperatures. As long as the soldering iron head is not kororoded by acidic soldering flux, and does not need to be hot melted glue or plastic, the soldering željezo glava je lako to kositar.
2. Using kiselo flux or lemljenje žica sa previše mnogo nečistoća
Kiseli fluks.
Neki početnici in elektronika like to use kiselo solder paste as a a lemljenje flux when zavarivanje. Ovo tip of flux is sever sever kiselo i donekle koroziv to some low-quality soldering iron tip tip soldering string wire can also cause blocky blocky or rofin alkohol otopina flux during zavarivanje. In addition, some cheap soldering wires wires a lot of nečistoće, and using this type of soldering wire can also cause the soldering iron head to not eat tin. Due to the poor wettability and flowability of this type of solder wire after melting, its solder joints become dark and not smooth and bright. If the poor quality of the soldering wire causes the soldering Causes the soldering Iron Head to Not Eat Tin, It Is Recommended To choose High-quality low melting spot Welding Wire Tiring Tiring LIFE LIFE.
