Maintenance of electric soldering iron in use
Keep the tip of the soldering iron clean because the tip of the soldering iron is in a high temperature state for a long time during soldering, and it is also exposed to substances that are decomposed by heat such as flux, and its surface is easily oxidized to form a layer of black impurities. reduce. Therefore, pay attention to the cleaning of the soldering iron tip at all times. Wiping the tip of the soldering iron with a damp cloth or damp sponge at all times is a common method. The cleaned soldering iron tip should be able to be wetted by solder, that is, the tip should be covered with a layer of solder, so that the soldering iron tip is easy to use when soldering.
Pay attention to the power-on time of the soldering iron
The electric soldering iron can reach the temperature of normal use within a short time after being powered on, so do not preheat it for too long in advance, otherwise it is easy to ablate the soldering iron tip. When not in use, cut off the power supply in time, and do not let it stay in the state of power on and heating for a long time, otherwise it will affect the normal use of the soldering iron tip and shorten the service life.
Soldering Iron Skills
Before each soldering, clean the tip of the soldering iron with a clean sponge or damp cloth that squeezes out moisture. During soldering, clean the old tin on the tip of the soldering iron first, and then follow the soldering steps for soldering. After soldering
, Cut off the power supply first, let the temperature of the soldering iron head drop slightly, and then coat with a new layer of tin, the tin layer has a better anti-oxidation effect. Generally, the electric soldering iron can work two minutes after it is powered on, and it can be used when it reaches the soldering temperature. If it is not used for a long time, the power should be disconnected.
During use and after use, always keep the tip of the soldering iron tip tinned. Reduce the chance of oxidation of the soldering iron tip and make the soldering iron tip durable.
When soldering, do not apply excessive pressure, otherwise it will damage or deform the tip of the soldering iron. As long as the soldering iron tip is in full contact with the solder joint, heat can be transferred.
The area where the soldering iron tip contacts the solder joint has a direct relationship with the heat. It is impossible for each user to own a variety of electric soldering irons, but the position of the soldering iron tip can be controlled freely during use. During normal use
, put the tip of the soldering iron tip in contact with the weldment and the pad, the contact area is small, and the temperature is slightly lower. If you want to increase the soldering temperature, you can change the position of the soldering iron tip appropriately to increase the area where the soldering iron tip contacts the solder and the pad. Certain circuits Among them, the pad is not in proportion to the weldment, and by properly adjusting the angle of the soldering iron tip during soldering, they can be heated evenly to help soldering.
