What are the tips and matters needing attention when using electric soldering iron

“Before each soldering, clean the tip of the soldering iron with a clean, squeezed wet sponge or damp cloth; during soldering, first clean the old tin on the tip of the soldering iron, and then follow the soldering steps to solder; after soldering, cut off the power supply first After the temperature of the soldering iron tip is slightly lowered, a new layer of tin is plated. The tin layer has a better anti-oxidation effect.

1. Use skills

(1) Before each soldering, clean the tip of the soldering iron with a clean, squeezed wet sponge or cloth; during soldering, first clean the old tin on the tip of the soldering iron, and then follow the soldering steps to solder; after the soldering, Cut off the power first, let the temperature of the soldering iron tip decrease slightly, and then plate a layer of new tin. The tin layer has a better anti-oxidation effect.

(2) The general electric soldering iron can be used after two minutes of electrification and reach the welding temperature; it should be disconnected from the power supply if it is not used for a long time.

(3) Keep the tip of the soldering iron head hung with tin during and after use to reduce the chance of oxidation of the soldering iron tip and make the soldering iron tip durable.

(4) When soldering, do not apply excessive pressure, otherwise the tip of the soldering iron will be damaged or deformed. As long as the tip of the soldering iron fully contacts the soldering point, heat can be transferred.

(5) The area of ​​the soldering iron tip contacting the solder joint is directly related to the heat. It is impossible for each user to have a variety of electric soldering irons, but the position of the soldering iron tip can be freely controlled during normal use. In normal use, the tip of the soldering iron tip touches the soldering piece and the pad, the contact area is small, and the temperature is slightly lower; if you want to increase the soldering temperature , The position of the soldering iron tip can be appropriately changed to increase the area of ​​the soldering iron tip contacting the soldering piece and the soldering pad; in some circuits, the soldering pad is not proportional to the soldering piece. During soldering, the angle of the soldering iron tip can be adjusted appropriately. Heat evenly to help welding.

What are the tips and matters needing attention when using electric soldering iron for AL

2. Matters needing attention

There are many ways to hold the soldering iron during soldering operation: front grip, reverse lift, pen grip, etc. No matter which grip you use, you must pay attention to the direction of the power cord, and draw it from the back of your hand or arm. Do not place the wire in the direction of the soldering iron tip to avoid scalding the wire, which may be dangerous. During use, the soldering iron should not be placed randomly. It should be placed on a suitable soldering iron stand to prevent the soldering iron tip from being damaged by collision. At the same time, please handle with care; place the soldering iron away from flammable and explosive objects. If you burn or scald items, cause a fire, the electric soldering iron must be cut off in time after you have used it. Extend the service life of the soldering iron. Prevent oxidation of the soldering iron tip.

Workers who use electric soldering iron for the first time often make some mistakes. For example, regardless of whether the electric soldering iron is used immediately or not, always plug the electric soldering iron into the power supply first to keep the soldering iron in working condition. When the soldering iron is to be used, it is found that the temperature of the soldering iron is too high or the tip of the soldering iron is seriously oxidized, which is difficult for some users. When soldering, regardless of the condition of the soldering iron tip, it is thought that components can be soldered as long as the soldering iron has heat. In the case of thick oxide layer or dirt, long-term soldering will not only cause poor soldering quality, but also lead to circuit boards. The pad is off or the components are damaged. This fully illustrates the consequences of not paying attention to the skill when using the soldering iron.
