1. Apply the flux on the bottom of the socket.
2. Melt the solder with a soldering iron.
3. Push the melted solder against the socket.
4. After a few second, the solder wets with the surface of the socket.
5. Do the same wetting process to the wire.
6. In the above process, make sure to put a bit excessive amount of solder on the socket and wire.
7. Put the wire very close to the socket.
