Fiducials are alignemt marks on PCBs. The standard for these is a 1mm copper circle surrounded by a 2mm soldermask opening. They are used for alignng your PCB via optical detection. For successfull operation there should be at least '''three''', better '''four''' which are places in the corners of your PCB to get the best accuracy for the placement of components. | Fiducials are alignemt marks on PCBs.
