How do we normally 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 degree of oxidation, as far as possible or do not go 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 soldering 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.
4, the fourth point to say is the problem of solder, solder also has good solder also has bad solder. In order to figure cheap, most people buy cheap solder wire. Cheap although cheap, the quality is very worrying, it is easy to appear solder slag, and even heat into a solder slag. It not only affects the quality of welding, but also very unfavourable to the iron head. Therefore can not be greedy cheap, buy a good solder wire is very important, generally speaking, buy 60 yuan a pound of solder wire is almost. I use is 65 yuan to buy 500 grams of solder wire, quite good, smooth solder joints, no tin slag.
5, the fifth point is also the author's last point to emphasise is the iron head, a good iron head can achieve twice the result with half the effort. Our daily use, if you use a round head or knife head can be, but to buy a good point of the soldering iron head. For example, the soldering iron head made of copper is very durable and has a strong antioxidant capacity.
