Automatic soldering iron black oxide coating analysis
Publish:電子產(chǎn)品全自動柔性組裝線,深圳市豪林精密機械有限公司  Time:2013-12-25
Automatic soldering machine solder tip black oxide coating reasons analysis:

1, The temperature is too high, especially at temperatures over 400 ℃, when so easy to get the solder tip oxided

2, Do not add the tin to whole surface

3, During the welding process, the flux inside the solder wire is too small, the surface of the tip will accelerate the rate of oxidation, especially at high temperatures, when the water-soluble flux highly corrosive, the tip will break

4, The sponge for cleaning the solder tip sulfur content is too high, too dry, or dirty

5, The solder tip contacted material such as plastics, lubricants or other chemicals

6, The tin wire is too impure

In short,
black oxide coating caused by many factors, but the above points are the main factors.
