I think the pcb has to be slightly bent to accommodate the angled position of the track ball. Making it like that helps alleviate stresses on the pcb.
Not just slightly bent. See here: https://ploopy.co/mini-trackball/

Makes sense! Thanks!

(I am trying to learn more about PCB design ideas and principles.)
Thanks!
