The first point is to wait! The first point is to wait!
This means that you should first apply the soldering iron tip only to the board or component terminal and wait until the metal part is properly warmed up. There are two reasons for this. The first is to create in advance the optimal environment for the solder to bond with the mating metal. Soldering is technically a process whereby the solder penetrates the surface of the mating metal and mixes with it, creating an alloy. At this time, it is necessary to create some high temperature conditions for penetration. The other reason is that when solder becomes a liquid, it has the property of spreading from a lower temperature to a higher temperature. Using this property, by warming the area to be soldered first, the solder will spread on its own, preventing too much or too little solder.
In the beginning, it is easy to get in a hurry and apply solder right away, but it is just right to calmly and slowly count 3 seconds in your mind after applying the soldering iron to the board and components. Components are basically safe from breakage after this amount of time as well.
The next point is to do it quickly.
When the part to be soldered is sufficiently warm, it is ready. Keep the tip applied and feed in the solder. At this point, the key is to feed the solder in as quickly as possible.
This is because soldering must be completed before the flux evaporates. The solder actually has a material called flux inside it with it. The flux chemically removes the oxide layer on the surface of the metal, making it easier for the solder to penetrate. When solder is melted, the flux dissolves together with it into a liquid. In fact, this flux has a low boiling point and evaporates quickly when heated to a high temperature. Before this flux evaporates, solder should be fed in quickly. Also, since solder becomes brittle if the temperature rises too high, from the standpoint of strength, it is also important to quickly send in solder with a relatively low temperature to cool it down so that the temperature does not rise too high.
The last point is that the amount of solder to be sent in should be only a little.
As is often said, good soldering produces what is called a fillet, a beautiful curve like Mt. Solder tends to be applied in large quantities, but too much solder will result in a dumpling-like shape, which reduces reliability because it is not possible to check whether the base is properly soldered. Extremely little solder also causes insufficient solder to spread, which can lead to poor contact.
Experienced technicians can quickly feed in the appropriate amount of solder based on their experience to determine how much is enough to form a clean fillet. This is a very difficult area to work with without experience, so practice diligently and get the hang of it little by little.
