How To Desolder Components

Repeating the Process

It is very rare to suck all the solder at the first round (see Figure 17). You will need to repeat the process. You may need to solder the component again in order to mix new solder with the old one, facilitating the solder to be melted and sucked. Another tip is to move the terminal back and forth with a small flat-tip screwdriver, in order to lose the terminal from the hole.

Then you will need to repeat the process again until you see that the terminal is lose from the hole. In Figure 20, you can see both terminals at the end of the process. Pay attention on how the terminals are centered and there is no solder holding the terminals to the holes.
