About Marks
To recognize that a workpiece is present or to determine its orientation on the fixture plate, the system uses marks
and fiducial marks. Marks are reference images (pictures of a small area on a workpiece) taken by the camera and
stored in a location called the Mark Library. The Mark Library appears in the Secondary View screen when the
Camera tab is selected. The stored images are shown in sockets in the Mark Library. Picture sockets are blank if
they do not contain a stored image.
A mark is a single image that the system uses to find a specific location on a workpiece. Fiducial marks are two
mark images that are used conjointly to (1) identify whether a workpiece is present in the proper XY location and (2)
to understand its angle of rotation, and then to make automatic adjustments to the program accordingly.

Best Practices For Selecting a Mark Image
• The selection should be on the actual workpiece (not on the fixture plate) because it is the workpiece position that
the system adjusts to.
• The selection should be unique. There should be only one selection of its kind within the camera view. For
example, don’t choose one of many small circles that are within the camera view.
• Sharp features are best. For example, the intersection of two lines in the capital letter T would be better for a mark
image than the center of a circle, which possesses no finite lines.
• An actual dispensing position, such as the corner of a silk-screened solder pad, is more effective than the broken
corner edge of a pallet of circuit boards because of the differences in their manufacturing precision.
• The further away fiducial marks are from each other, the more precise the system will be in locating them on a
workpiece.
Mark Image Files
You can store 240 mark images in the sockets available in the Mark Library. The Mark Library appears in the
Secondary View screen (refer to “Secondary View Screen” on page30 for more information). These marks are
stored as files on the DispenseMotion controller under D:\ever_sr\mark.
