Five-step training of electric soldering iron
The five-step method is a very effective teaching method for beginners to acquire manual soldering technology and merits discussion in its own section.
Many electronic hobbyists utilize the same soldering technique, which involves dipping the soldering iron tip in solder first, placing it on the solder joint to heat it up, and then applying solder to wet the weldment.
This approach is not the proper one to use. This method also allows for the welding of the weldment, but the quality cannot be guaranteed. In light of what we already know about the soldering mechanism, this is not difficult to comprehend.
prepared for welding
Prepare a soldering iron and solder wire. At this time, it is especially stressed that the soldering iron's tip be kept clean because it can become stained with solder.
Warming the weldment
Touch the soldering point, being careful to keep the soldering iron heating all areas of the weldment, such as the lead wire and pad on the printed board, and then being careful to let the flat part (larger part) of the soldering iron tip contact the greater heat capacity A small heat capacity soldering iron tip is in contact with the weldment on the side or edge to maintain the
3. melted solder
When the weldment is heated to a temperature that melts the solder and the wire is placed on the solder joint, the solder begins to melt and wet the solder joint.
4. remove solder
Remove the solder wire after a certain amount of solder has melted.
5. remove the soldering iron
Remove the soldering iron when the solder has completely wetted the solder joint, and note that the direction of removing the soldering iron should be approximately 45°
