Basically it is a round solder mask opening with round bare copper in the center.

Pcb fiducial marker. The fig 7 below shows positions of the fiducial marks on the board with one qfn and one qfp package with small pitch. Fiducial marks are recognition marks created in the form of small pads on the pcb board to act as reference points for pcb stencil alignment and for automated component placement by pick and place machines. If you want to get the best out of machine assembly you need to get your fiducial markers right. Bare copper has a smaller diameter than the solder mask opening.

There are few important guidelines when it comes to fiducial placement in your design. This masking area eliminates any glare that might reflect into the camera from the glossy finish of the masking. So when you are designing your next pcb or revising and existing pcb please consider adding fiducials to your design. The fiducial marker is made by placing a non drilled copper layer in a circular shape.

Best practices for using fiducial markers in pcb design. Fiducial marks come into play when you have a pc board assembled by automated pick and place machinery robots that put the components on your board. A fiducial mark marker is a circuit pattern recognition mark or marker. A fiducial marker or fiducial is an object placed in the field of view of an imaging system which appears in the image produced for use as a point of reference or a measure.

Although the fiducial cannot be saved as a library component a quick and easy solution for future use is to save the fiducial as a pcb design with the fiducial. Many designers have found that using a 1mm round fiducial with a 2mm masking area around it works best. Automated assembly machinery requires incredible precision to accurately place a 0201 size resistor or 2mm x 2mm chip scale micro bga. These points are also measurable and act as a frame of reference.

When working on a new design also open this pcb design and you can copy and paste the fiducial to your current design as shown below. In pcb design a fiducial marker is a rounded shape of copper that acts as a reference point for pick and place assembly machines. It is also helpful and sometimes necessary to place four fiducial markers near panel corners. A guide to fiducial marks for pcb assembly fiducial marks are precision targets built into a pcb surface which are used by a vision equipped pick and place machine to fine tune it s placement accuracy.

Because they are formed in the outermost copper layer. However it also depends on the assembly machine. Pick and place machines use fiducial marks as referent points on the pcb to position. 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.
