Ps4 and Ps3 controller?

I recently had a problem with my Ps4 controller and was able to fix it by unscrewing it.

Now I need a new magnetic plate (which is built into the analog sticks) and wondered if the ps3 has the same magnetic plate as the ps4?

Finally, only the analog sticks were exchanged and not the magnetic disks, I think everyone has information about them?

What do you mean by magnetic disk? Do you mean the speaker, which also has a magnetic attachment?

I mean in the stick or in the analog stick there are 2 boards one for left and right and the other for top and bottom
