Gravity Point Example
Gravity Point is an OptiSureAOI feature that allows you to create two Fiducial Marks in the center of a line, one at
the beginning of the line and the other at the end of the line. Then, if a subsequent dispense must be made on a line
that is thicker or thinner, the system can dispense through the center of that line using the Fiducial Mark offsets.
PREREQUISITES
To learn how to use this feature, draw two lines of different thicknesses on a sheet of white paper and use it as a
workpiece template.
