TO-220 FET-N, V-reg lying flat on PCB

Hi Old_Grey,

Just in case you didn't catch it, the black circle in the heat sink of your FET is in the copper layers and it drills a 4mm hole through your board. You have also duplicated the elements in the embedded copper1/copper0 layer into the copper1 layer.
