SMD
Surface mounted device
A Surface Mounted Device (SMD) does not have drill holes in its pads and a pad has its land pattern only on one copper side (layer 16, copper top). In TARGET 3001! every component is constructed in top view and that's the way it is saved to the data base. This does not necessarily mean that it needs to be mounted on the top side of the board as well. By default TARGET gets SMD parts into the layout already flipped to the bottom side of the board. You can flip it to the top side of the board by the Mirror command (keyboard key [m]). You can change this default setting for now and coming projects in the "Package import" dialog. In the pads themselves there are no drills (drill hole diameter =0).
