5 steps for correct soldering with a soldering iron
Step 1: Prepare welding materials
First of all, we need to prepare the welding materials, such as soldering iron, solder wire, solder board, components, and flux. In addition to the initial process, we also need to use soldering iron and solder wire. Generally, we use our right hand to hold the soldering iron and the left hand to hold the solder wire. We then install the components onto the PCB and place them on the table for soldering. Pay attention to the high temperature of the 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 welding element
After heating the soldering iron, it is best to place it in the flux for a moment. It would be even better if some flux could be added to the soldering area, which makes it easier for us to solder. When soldering integrated patches, we have a better understanding of the necessity of adding flux. The 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 soldering iron reaches a certain temperature, we start soldering. First, place the solder wire on the pins of the component with solder, then bring the soldering iron close to the solder wire, place the tip of the soldering iron on the solder wire for a moment, and after the solder melts, the solder solution can surround the pins of the component. When soldering integrated chips, 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 half 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 on the soldering area anymore. We should promptly move the solder away from the soldering area so that the solder liquid can solidify.
Step 5: Remove the soldering iron
After removing the solder wire, in order to make the soldering more beautiful, we can use an electric soldering iron to melt the solder solution again at the original soldering position, to avoid the phenomenon of virtual soldering caused by insufficient melting of the solder wire. When carrying out actual operations, do not place the soldering iron tip on the area to be soldered for a long time. If the soldering iron temperature is too high, it may cause the solder pad to fall off, which will result in the PCB board being scrapped.
