I have a PS4 controller that I want to replace the joystick on, so I disassembled the controller, added flux, added additional solder to all the joints, and removed the faulty joystick with a heat gun. Everything went well, but I ran into a few problems during the next step which was removing all the solder from the joints with a soldering iron, solder sucker, and a wick. The problem is that I have a few joints with a incredibly thin amount of solder that is quite difficult to remove since I can't get my iron and sucker on it at the same time. What is the best way to remove the solder (see picture 1)?
I have tried adding additional solder, adding more flux, using a wick, and heating up the board with a heatgun then switching to the iron. I have even tried attaching a resistor to the joint, adding solder, and then attempting to remove the solder again. What do I do? Note: This is for fun/practice, and not for a professional repair, so I am willing to experiment.
