5-step method for correct soldering with an electric soldering iron
Step 1: Prepare welding materials
Step 3: Add solder wire
Step 4: Remove the solder wire
Step 5: Remove the soldering iron
After the solder wire is removed, in order to make the welding more beautiful, we can use the electric soldering iron to re-melt the tin liquid at the original welding position to avoid the phenomenon of virtual soldering caused by insufficient melting of the solder wire. During actual operation, do not hold the soldering iron tip for a long time. Place it in the place to be soldered. If the temperature of the soldering iron is too high if it stays here for a long time, the solder pad may fall off, which may cause the PCB board to be scrapped.
