1. Billboard Thres (um)
● 3D Inspection
● Fail Criteria:
Measured height > (Component height + Billboard threshold)
2. Billboard 2D
● Turn on 2D billboard inspection. The algorithm will perform 2D + 3D
inspection. Either 2D or 3D algorithm detect a failure, the inspection will fail
the component as billboard
a. Billboard Grey Thres
b. Billboard Image Plane
● Select the one that having best contrast among the component body and
background.
