Classification of electric soldering iron
There are two kinds of electric soldering irons commonly used now: external heating type and internal heating type. External heating type electric soldering iron has high thermal efficiency and fast heating speed. The internal heating type electric soldering iron has higher power. Use the same method. If the tip of the electric soldering iron is oxidized. Use a knife to scrape off the oxide layer on the front end, wipe it clean with a damp tin-absorbing sponge, and then tin-plate immediately to prevent re-oxidation. The flux can make the solder and components better welded together. The most commonly used is a mixture of rosin and alcohol. Among the solder wires currently used, some of the solder wires are hollow in the center and have flux in them. There is no need to use additional flux when using this welding wire. But if it is to be welded or repaired, the surface of the solder joint pin of the circuit board has become black and oxidized. It is best to use a small amount of flux to enhance the soldering quality
In addition, there are some essential auxiliary tools, soldering iron stand, tin suction device. Tweezers, partial mouth pliers. Brush, etc. The soldering iron stand should be a special shelf with one or two slots (for putting tin sponge) in the base part, not a random shelf, so that the tip of the soldering iron can be wiped at any time. easy to use. A solder sucker can help you get rid of excess solder on the circuit board.
