How to deal with oxidised black soldering iron tip without tin staining
Soldering iron oxidation cause is the use of people did not maintain the iron head, how to deal with oxidation black iron head, first of all, use a knife to the black layer of the iron head scraped off, until scraped out of the original colour of the copper yellow, and then add rosin a solder on it. Remember not to use the iron when the front full of solder, this is called maintenance iron head. It will not occur oxidation black.
With a knife or fine gauze to remove the surface of the oxide layer, and then the soldering iron head dipped in rosin full of solder on the line, pay attention to the use of the process for a long time without it, it is best to adjust the temperature down or directly to the soldering iron power outage.
Change a good point of the soldering iron head, or any effort is futile, get on the tin and then oxidised not sticky kick, normal use first on the rosin.
Scratch with a knife, dew white head, dip a little rosin, in the addition of solder, it's good, do not use the soldering iron, the head must be added to the solder burning, otherwise it will not be stained with tin.
How to use the soldering iron correctly?
1, the first point to say is that this flux (flux paste) the use of the problem, most of the flux is an acidic flux, the soldering iron head have a certain oxidation, try not to use.
Here to recommend a better way to make flux, that is, the rosin crushed into powder, poured into the alcohol solution for full dissolution. The ratio is generally 40% of the rosin powder plus 60% alcohol solution, rosin a little more is not a problem. Need to pay attention to not be able to use medical alcohol, use more than 90% alcohol solution, at the same time the container to maintain a sealed state.
2, the second point to say is that this power problem, many small partners after the use of habit is not timely unplugged. Soldering iron head in the heating state, the natural oxidation of non-stick solder. Therefore, daily use need to do, finished in time to cut off the power supply.
3, the third point to say is that many people ignore the soldering iron head tinning problem, in order to save trouble, most of the use of the finished soldering iron
Iron will not go to the soldering iron head tin. Even after the iron head power off, its temperature is also very high, will also occur with the air oxidation, and in the power off before it is tinned, you can avoid it being oxidised.
