The correct 5-step welding method for electric soldering iron
Step 1: Prepare welding materials
Firstly, we need to prepare the welding materials, such as soldering iron, soldering wire, solder board, components, and flux. In addition to the first time, we also need to hold the soldering iron and soldering wire. Generally, we hold the soldering iron in our right hand and the soldering wire in our left hand, place the components on the PCB, and wait for soldering on the table. Pay attention to the high temperature of the electric soldering iron after heating for a period of time. Do not touch it with your hands, otherwise it may cause burns.
Step 2: Heat the welded components
After heating the electric soldering iron, it is best to put it in the flux for a moment. It would be even better if some flux could be added to the welding area, which would be more convenient for us to weld. When welding integrated patches, we have a better understanding of the necessity of adding flux. The electric soldering iron does not need to be placed in the flux for a long time, about two seconds.
Step 3: Add solder wire
After the electric soldering iron reaches a certain temperature, we start welding. First, place the soldering wire on the pins of the soldered components, then let the electric soldering iron be close to the soldering wire. Place the electric soldering iron head on the soldering wire for a moment, and after the soldering iron melts, the solder can surround the pins of the components. When soldering the integrated chip, be careful not to add too much solder.
Step 4: Remove the solder wire
After the solder melts and drips onto the components to be soldered, we have completed most of our work. The next step is to wait for the solder wire to solidify, so there is no need to place the solder wire at the solder joint. We should promptly remove the solder from the joint to allow the solder liquid to solidify.
Step 5: Remove the soldering iron
After removing the solder wire, in order to make the welding more aesthetically pleasing, we can use an electric soldering iron to re melt the solder liquid in the original welding position to avoid the phenomenon of insufficient melting of the solder wire leading to virtual soldering. When performing actual operations, do not leave the soldering iron head in the area to be welded for a long time. If the soldering iron temperature is too high, it may cause the solder pad to fall off, which may cause PCB to fall off
Abandoned bulletin board.
In short, it is best for us to follow the standard steps when welding, especially for beginners, to avoid some unnecessary losses.
