Altium Designer Tutorial 7: How to create a Fiducials Marker in Altium Designer 21. I tried to explain in details what is Fiducials Marker, How to create Symbol, Footprint and Integrate in Integrated Library in Altium Designer. #Fiducial marker or fiducial refers to the reference point on a printed circuit board (PCB). Through #fiducials, it is possible for solder paste printers, automatic placement machines, and optical inspection systems to precisely measure the circuit structure. Fiducials are alternatively also referred as circuit pattern recognition marks. if you have any questions please write me at "email@example.com".
