Notes:
- I deliberately made the courtyard clearance smaller than required for BGA packages (0.25mm instead of 1 mm). This is required from design reasons. One wants to keep the gate loop small as possible, in order to provide proper switching.
- I had to place the Fab-Layer RefDes outside the Fab-Layer outline of the part, since I wasn't able to fit 3 characters inside.
