.TST file creation
The .tst file is a graphic representation of the panel allowing inspection of the panel by the AOI system.
The .tst file contains:
The information about the size and arrangement of the board.
The CAD coordinates of fiducials and skips.
The CAD coordinates of components and pads.
The position of the acquisition zones and the camera travel for inspection.
The setting of the 5 light levels for each zone.
You can access each component, paste pad or fiducial by clicking directly on it.
It is generated from a .vis file and must be linked to a component library.
Errors on the .vis file can only be detected during generation of the .tst file.
The .tst file is the file to which the lighting parameters and the image treatment (library) are linked for each com-
ponent or type of component.
You can place the .tst file anywhere on your hard disk. However, the .tst file that you intend to use for inspection
in the production mode must be installed in C:\VIT\Data for it to be selected.
