The main purpose of soldering iron is to solder components and wires, which are also classified according to their mechanical structure, function and use. The soldering iron is an indispensable tool for electronic production and electrical maintenance. When the mobile phone repairs and replaces the components on the circuit board, the soldering iron will not be tinned. What should be done at this time? The soldering iron does not stick to the tin. It may be because the use time is too long, resulting in oxidation of the surface of the soldering iron copper head, resulting in a layer of copper oxide on the surface, which hinders the tin. Treatment: The usual treatment method is to scrape off the copper oxide film with a knife to reveal the copper that is not oxidized by air. Then put it in a rosin box and rub it with tin, you can use it normally. But this method of removal is slow and incomplete. The drawback is that the copper head will become thinner and affect the heat transfer, causing the temperature to drop and even damage the copper head. Another treatment method is: immersing the oxidized copper head in a container containing alcohol with a handle of a soldering iron, and taking out the oxide for 1-2 minutes, the oxide is completely removed, and the copper head is completely renewed. This is because copper oxide and alcohol (C2H5OH) are heated to produce a chemical reaction, which reduces copper and has no corrosive effect on the soldering iron tip. Now you should know how to handle the soldering iron without soldering. Concerned about surprises Label: How to deal with the soldering iron tip?
