From experience, dont do this unless you have a very good desoldering setup. The joysticks have 14-16 pins and you need to be able to desolder every single one perfectly to get it off the board. Getting the new one on can be similarly difficult.

I have seen some custom tips for these but haven’t tried them yet.

If that hasn’t dissuaded you, then calibration itself is easy. Just connect it to a computer and go to the calibration website (it’s a GitHub page that does it all in JS).

Be ready to spend at least few hours if you decide to do.

I never soldered anything except 3,5mm jacks before. Took me around 5h for dualsense first time. Used only cheapest suitable Chinese iron and copper for desoldering. Second controller took me around 3 hours. For 3rd one I bought electronics clamps because it was too hard to solder and pull sensors at the same time. Still took 3 h because it was dualsence edge which harder to work with and you have to jump contacts to unblock calibration mode.

Last time I didn’t bother trying to unsolder without breaking original sensor. Basically I crashed the sensor to leave only pins in the schema. It’s much easier to unsolder pins one by one then trying to melt and pull multiple pins by pulling sensor. This also more risky because it’s easy to break off other elements. I broke off one element once. It took me A LOT of attempts to solder it back coz it’s so small you can even touch it without moving it. We are talking less than millimeter probably.

Be aware you need iron which can reach 400 C. It’s min temp required to melt whatever alloy they use in Sony’s factory.
