3. Operation steps
(1)The soldering iron heats the pins and pads at the same time
(2) Solder close to the tip of the soldering iron, add tin
(3) Remove the tin bar first, then remove the soldering iron
4.Use skills
(1) To tin the copper wire, you should tin-plate the tip of the soldering iron first, and then tin the solder from the contact between the soldering iron and the copper wire. Many solders have their own flux, but long-term heating will cause the flux to evaporate. Flux or fresh solder will do.
(2) Before welding, the tip of the soldering iron sticks some tin in advance. When touching the weldment, the contact area and heat conduction are increased, which can heat the solder joint faster and melt the solder.
(3) To weld two objects, first tin-plate both ends (the amount should be enough), it will be smoother.
(4) Before welding, the oxide of the weldment should be removed, such as steel wool, eraser, and board washing water can be used (use acid-containing flux, and it should be cleaned in time to avoid acid corrosion of components). Before soldering the enameled wire, burn it with a lighter, and then wipe off the surface paint with a towel.
(5)The shape and size of the soldering iron tip and the thickness of the solder should match the weldment
(6)Choose an appropriate temperature, if the temperature is too high, it will damage the soldering material and the tip of the soldering iron.
