Popular science about the correct posture of holding the soldering iron
There are three commonly used holding methods for electric soldering irons:
Pen grip method: the most commonly used grip method, suitable for soldering electronic components on the PCB on the operating table.
Overhand grip: Suitable for medium-power soldering irons or soldering irons with elbows.
Reverse grip method: Use five fingers to hold the heat-insulated handle of the electric soldering iron in the palm, which is suitable for high-power electric soldering irons and soldering devices with large heat dissipation.
If it is a newly purchased electric soldering iron, remember to tin the new soldering iron tip first, otherwise the soldering iron tip will be easily oxidized and blackened, and it will not be easy to eat tin in the future. Plug the new soldering iron into the power supply, and apply rosin to the tip of the soldering iron as the temperature gradually rises; when the rosin smokes and the tip of the soldering iron starts to melt the solder, tin the tip of the soldering iron with a tin wire so that the tin is fully wrapped The entire tip of the soldering iron, so that the tip of the soldering iron can be coated with a layer of solder to achieve a bright surface. After soldering, before turning off the power, clean the soldering iron tip with a cleaning sponge, and then tin the soldering iron tip to protect the soldering iron tip from oxidation.
When the soldering iron is in use, do not hit it hard, and prevent accidental drops, so as not to damage the soldering iron. When there is too much solder on the tip of the soldering iron, do not shake it around to avoid scalding others. You can use the copper ball electric soldering iron cleaner to clean it, which is easier to use and will not cause the temperature of the soldering iron tip to drop excessively. If you want to remove the soldering iron tip The tin on the surface is cleaned very clean. After rubbing the copper wire ball, you can quickly wipe the tip of the soldering iron on a damp cleaning sponge a few times. When Lao Wu went to the production line, he often saw workers use that kind of round paper tube for materials, cut it and seal one end, and then beat the paper tube with a soldering iron desperately, so as to use the force of inertia to throw the residual tin onto the paper tube. In the cylinder, this method is not recommended by Lao Wu. If it is an ordinary electric soldering iron, it may not hurt so much. If it is the soldering iron handle of a precision high-frequency soldering station, because there are still some precision electronic components in the handle, repeat If you hit it hard, it will hurt more.
