Hi I have 4 layer board layered as follows.
For the power and ground planes I have done zone fills...
I want to attach the PCB ground to my chassis using a screw. I initially just had a padded mounting hole, but someone suggested to fortify the hole with vias incase the screw somehow damages the plating and the connection no longer happens, but he's not sure how it works in KiCad.
I noticed there's a mounting_hole_pad_via footprint/component. And I used that. Is that enough, or do I need to do anything else special? The mounting hole is already attached to the ground fill. The surrounding holes are through-hole and marked as all copper layers.
Pink is the ground pour, yellow is the power pour.
