![]() What are Fiducial Markers?Īlthough it sounds like a financial term, the term "fiducial" means a fixed basis of reference for comparison purposes. ![]() Fiducial markers provide reference points for imaging systems. With the help of the indexing (positioning) system, the PCB is positioned per the program parameters, however, this positioning is not exacting enough for component placement. The targets for an SMT vision system are multiple: matching the circuit pattern of the artwork with the top or the bottom of the fabricated printed circuit board (PCB), determining the location of the PCB along the x, y, and z planes, and locating the precise position on the circuit to place a specific component. Did you ever wonder how vision and robotic systems in surface mount assembly machines (SMTs) are able to situate electronic components exactly where they need to go on a tiny printed circuit board, within extremely close tolerances?
