1. Warpage Compensation Mode
● Compensate the 3D height if there is an obvious board warpage
happen.
● The difference for this 3 modes is the region to select the
reference board heights. Refer to pictures below for the
region
● Multiple points are automatically selected from the region as
reference board height. Standard deviation of heights is
calculated to filter outlier points with abnormal height. This
procedure ensures accuracy of auto warpage compensation
even there are components fall inside blue region.
