Apply flux to all contacts before soldering. I use flux even though my solder contains it as well.
Apply solder to all the 14 contacts. Make sure that there is a good bond between the contacts of the analog stick and the solder pads on the board.
Here all 14 contacts have been soldered. All that is left now is to wash of the flux with some isopropyl alcohol and to reassemble the controller.
