Soldering iron head does not hang tin how to do, three processing methods to see the
In the soldering iron welding device, sometimes encounter the soldering iron head does not stick to the tin situation, the soldering iron does not hang tin problem, mainly divided into the following kinds:
1, long time use, the soldering iron head surface oxidation occurs, in its surface to generate a layer of copper oxide, it is easy not hang tin. Soldering iron head in the lead-free soldering process, sometimes the soldering iron head does not stick to the tin phenomenon.
2, select the temperature is too high, easy to make the soldering iron head tin surface intense oxidation.
3, "dry burning" soldering iron head, can also lead to the emergence of the soldering iron head does not hang tin problem.
4, the use of flux is highly corrosive, caused by the rapid oxidation of the soldering iron head.
5, the use of neutral activity of the flux, not often clean up the oxides on the soldering iron head.
Soldering iron does not stick tin processing method
Method 1: The oxidized layer on the surface of the soldering iron head can be solved by hanging off with a knife and then dipping it in rosin. But this method is not complete, time will damage the iron tip, resulting in poor heat transfer iron table.
Method 2: oxidized soldering iron tip immersed in a container of alcohol, about 1 to 2 minutes after the removal, the oxide is completely removed, the soldering iron tip a new look. The reason lies in the oxidized copper and alcohol heating, it will produce chemical reaction, restore the copper, no corrosive effect on the soldering iron head.
Method 3: According to the maintenance specification correct use, maintenance of the tool, try to use low temperature, reduce its oxidation rate, prolong the service life. Do not press hard, as long as the contact is good heat will be transferred normally.
The basic steps of welding
1, in order to make the soldering point conductivity is good, with sandpaper first soldering iron head polished clean. Note that the strength should be light, do not make the soldering iron head excessive wear, excessive wear and tear easy to be oxidized.
2, the soldering iron will be electrically heated, until the temperature can make the solder melting, the soldering iron head coated with flux, and then evenly coated with solder on the soldering iron head.
3、With the soldering iron with the soldering iron head to contact the soldering point, when the solder submerged soldering point, slowly pull up the soldering iron.
4, after the completion of welding, the soldering iron will be powered off on the soldering iron stand. Note, be careful by the residual temperature burns.
5, the circuit board on the residual flux, you can use alcohol to clean up, to prevent carbonization of the flux affect the normal operation of the circuit.
