Five tips for using electric soldering iron, four precautions for using electric soldering iron
1. Before welding, clean the tip of the soldering iron with a clean, squeezed wet sponge or damp cloth; during welding, clean the old tin on the tip of the soldering iron, and follow the welding steps for welding; after welding, cut off the power first, After the temperature of the soldering iron tip is lowered slightly, a new layer of tin is plated on it, and the tin plated layer has a better anti-oxidation effect.
2. Two minutes after the electric soldering iron is energized, it can be used when it reaches the soldering temperature; when it is not used for a long time, it needs to be disconnected from the power supply.
3. During and after use of the electric soldering iron, keep the soldering iron tip tinned to reduce the chance of oxidation of the soldering iron tip and make the soldering iron tip durable.
4. When soldering with an electric soldering iron, do not apply excessive pressure to avoid damage or deformation of the soldering iron tip. As long as the soldering iron tip is in full contact with the solder joint, the heat can be transferred.
5. There is a direct relationship between the area of the soldering iron tip in contact with the solder joint and the heat
The position of the soldering iron tip can be freely controlled during use. During normal use, the tip of the soldering iron tip is in contact with the weldment and the pad, the contact area is small, and the temperature is slightly lower; in order to increase the welding temperature, the position of the soldering iron tip can be appropriately changed so that the soldering iron tip touches the weldment The area of the pad increases; in some circuits, the pad is not proportional to the weldment, and the angle of the soldering iron tip can be properly adjusted during welding to make it evenly heated and improve the welding quality.
Precautions for the use of electric soldering iron
1. When using an electric soldering iron for soldering operations, the electric soldering iron has a variety of holding methods, mainly including the forward holding method, the reverse lifting method, and the pen holding method.
No matter what kind of holding method is used, we must pay attention to the direction of the power wire. It should be led from the back of the hand or the direction of the arm, and the wire should not be placed in the direction of the soldering iron tip to prevent the wire from being burned and causing danger.
2. During the use of the soldering iron, it should not be placed arbitrarily, but should be placed on a suitable soldering iron stand to prevent the soldering iron head from being damaged by collision; at the same time, it should be handled with care; the soldering iron should not be placed close to flammable and explosive objects , To avoid scalding, scalding items, causing a fire, the electric soldering iron should be cut off in time after use. Extend the life of the soldering iron. Prevent oxidation of the tip of the soldering iron.
3. When using the electric soldering iron for the first time, it is easy to make some mistakes, such as: no matter whether you use the electric soldering iron immediately or not, always plug the electric soldering iron into the power supply first, so that the soldering iron is in working condition.
When it was time to use the soldering iron, it was found that the temperature of the soldering iron was too high or the tip of the soldering iron was seriously oxidized, making it difficult to use. In the case of thick or dirt, long-term soldering will not only cause poor soldering quality, but also cause the pads of the circuit board to fall off or the components to be soldered.
4. When welding, first handle the electric soldering iron well before welding, not only the welding quality is good, but also the welding time can be saved
