There are two ways to do this I recommend hot air, but you can also use pliers
Hot air
Add plenty of kapton tape to the surrounding components if you use hot air
Pliers
Carefully cut the shielding, and then remove it and the black plastic
Apply flux to the gold fingers and remove them. These pads are the most important, so be gentle!
Clean off the original solder using solder wick. Once again, be gentle as to not pull up any pads
installing the board
Align the new board to the pads and solder it to the pads. Use flux to help. Make sure to also solder to the pads around the board as this will help anchor the flex to the device

To remove the micro SD from the slot, its best to use tweezers.
