How to solve the soldering iron tip does not stick to the tin
1, prepare high quality solder, rosin, high temperature sponge. Put the soldering iron on the power supply, wait until its temperature is high, insert the soldering iron head into the rosin, back and forth for shaking. Then take out the ready solder, contact the soldering iron head can melt.
2, if the iron head has oxidised black, you can prepare a file (no file, if you prepare sandpaper is also available) with a file or sandpaper on the iron head for grinding, the iron head surface of the black oxide layer can be sanded off.
File
3, the soldering iron is generally made of copper metal, oxidation of the surface will form a black copper oxide (CuO) copper oxide is not sticky solder, you can insert the soldering iron into the content of 90% alcohol solution. It should be noted that the unheated state should be put into, and then electrified, 1-2 minutes after the removal, you can solve the problem of oxidation of non-stick solder.
Correct use of soldering iron?
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 has 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 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.
5, the fifth point is also the author of the 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.
