What should I do if the tip of my soldering iron burns?
About the soldering iron soldering iron head burned to death treatment method, the soldering iron with a long time soldering iron head often do not dip tin, with a knife to scrape off the film of oxidized copper, through the inside is not oxidized by the air of copper, and then put into the rosin box dipped in a little bit, and then dipped in tin, you can continue to use the electric soldering iron.
Soldering iron iron head burned to death processing method
Electricians often use soldering iron to welding components, soldering iron with a long time iron head often do not dip tin, this is due to the use of soldering iron for a long time, the surface of the copper head of the soldering iron will be oxidized, generating a layer of copper oxide (CuO), preventing the dip on the solder.
Soldering iron iron head burned to death
The general customary treatment method is to use a knife to scrape off the copper oxide film, through the inside is not oxidized by the air of copper, and then put into the rosin box dipped, and then dipped in tin, which can be used normally.
But this method is slow and incomplete removal, at the same time, long-term scraping down, the copper head will become thin and affect the heat transfer, resulting in a drop in temperature, or even damage to the copper head.
Fast and efficient way to deal with: hold the soldering iron wooden handle, the oxidized copper head immersed in a container of alcohol, after 1-2 minutes to remove, oxides on the thorough, clean removed, copper head new, this is because the copper oxide and alcohol (C2H5OH) heating chemical reaction, and then restore the copper, the soldering iron head did not have a corrosive effect.
Soldering iron soldering temperature
1, soldering chip, code switch and other components of the soldering iron temperature of 343 ± 10 ℃;
2, welding color ring resistors, ceramic capacitors, tantalum capacitors, short-circuit blocks and other components of the soldering iron temperature at 371 ± 10 ℃;
3, repair general components (including IC) iron temperature within 350 ± 20 ℃;
4, the repair of thick pins of power modules, transformers (or inductors), large electrolytic capacitors and large-area copper foil pad soldering iron temperature at 400 ± 20 ℃.
5, SMD, assembly inspection welding, cell phone production line soldering iron temperature requirements in strict accordance with the production station inspection welding operation guide book on the temperature requirements;
6, lead-free special iron, temperature of 360 ± 20 ℃.
SMT components welding, disassembly, need to wear electrostatic ring electrostatic ring also known as electrostatic wristbands, generally made of conductive fibers ring-shaped wide tight band.
Main role: to protect electronic components from electrostatic breakdown. When using, must pay attention to connect a good ground, or else "useless", does not work.
