Using three fiducials enables the machine to determine pcb offset in both the x and y axes as well as to determine if the board has rotated during clamping allowing the machine to rotate parts to be placed to match. The fiducials are etched about halfway through the stencil. You can adjust the lighting in each individual program not just a global lighting change. We did not get them from superman the green camera vision systems are just good. For pcb assembly this means that our stencil printing machine pick and place machine and aoi machine can recognize where the pcb is when it goes to perform its task. It may be either something placed into or on the imaging subject or a mark or set of marks in the reticle of an optical instrument.
