Depending on the material and the surface characteristics of PCBs, many different types of fiducials are used in electronics manufacturing. In addition, fiducials can indicate clusters or very large boards.
In any case, thanks to their adjustable lighting angles and colors, the multicolor PCB cameras in SIPLACE placement machines are able to recognize fiducials quickly and reliably even under difficult conditions. The spectrum of fiducials is virtually unlimited and ranges from daggers and double-daggers to pound signs, crossed circles and rectangles. SIPLACE multicolor cameras can recognize all of them to ensure accurate component placements.
Additional information is provided by ink dots to prevent the wasteful placement of good components on bad boards.
