Could someone please explain what the green bit in the center is and what the silver ring on the outside represents? I'm trying to create a hole of a certain size and just want to know the difference between 'Hole Size' and "X-size and Y-size under Size and Shape".
Green portion represents the hole and grey portion represents the pad surrounding the hole for electrical/mechanical connectivity.
So in pad properties,
- Hole Size: Specify the hole size. (It is advisable to increase the hole size by some percent to ensure smooth entry/exit from the hole)
- X-axis: Size of the pad in x-dimension(left-right)
- Y-axis: Size of the pad in y-dimension(top-bottom)
The value of X-axis and Y-axis will be same if your pad is circular, and different otherwise
