I follow your blog for some time and started to follow it when finding your kicad tutorials. I'm designing a board with kicad but I don't know how I should design the thermal pad. (I wanted to post an image but not allowed)
The component is a tps63061 and you can see the board layout at page 31 on datasheet ti.com/lit/ds/symlink/tps63061.pdf
Do you have any idea how to do that?
