- qfn.fpd: where were no measurements at all - added them - qfn.fpd: parametrize 0.1 mm border between central pad and land pattern and increase it from 0.1 mm to 5 mil (recommended by Adam Wang) - qfn.fpd: define solder paste of central pad separately and give it a 5 mil border to the pad edge, 10 mil to the copper edge (parameters recommended by Adam Wang)
