1. It is better to use an adjustable constant temperature soldering iron;
2. When using for the first time, the tip of the soldering iron must "eat tin";
3. When the soldering iron is not usually used, keep a certain amount of tin on the soldering iron tip. Do not store the soldering iron tip on the soldering iron rack after cleaning it on the sponge;
4. The sponge needs to maintain a certain amount of water to keep the sponge moist all day;
5. When the soldering iron starts to use, the tip of the soldering iron needs to be cleaned, but it is not necessary to clean the tip of the soldering iron on the sponge during use, just put the tin on the tip of the soldering iron into the tin-collecting cardboard box, so as to keep the tip of the soldering iron. The temperature will not drop rapidly. If it is difficult to extract tin on the IC, add some tin on it (because the tin wire contains flux), you can easily extract more tin;
6. It is normal for the temperature of the soldering iron to be between 340 and 380 degrees. If some sensitive components can only accept the soldering temperature of 240 to 280 degrees;
7. The tip of the soldering iron is too strong, and it cannot be handled with metal devices such as knives, but with rosin or tin wire;
8. After using it every day, clean it first, then cut off the power immediately.
