In the Libraries window, you may have libraries different from that shown in Fig. Registration is accomplished using alignment patterns called fiducials and tooling holes in the board, which slide onto guide pins. However, if parts are not in proper alignment and thermal gradients do not melt the solder on all pads at the same time, the component may stand up on one end called tombstoning.
