.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.

The .lk file is a text file which contains the
correspondence between the names of
the components in the .vis file (called
Part Number) and the names of the mod-
els in the libraries (customer and stan-
dard library).
The .lk file is helpful to easily create the
.tst file. Anyway it is optional, and the
links can be done manually during the
.tst file creation (wizard).
.lk file characteristics:
Identical libraries for all users,
Contains all common components,
Each user can update his/her own li-
brary,
Components are shared as they are
not linked to an environment,
Easy creation of new components.
The .lk file must consist only of numbers and let-
ters. The user name of the Jedec and your Jedec
name must contain no /, -, _ to allow use of the .lk
file.
Comments line begin with an @ (you can use # in
your component names).
The .lk file can be located where you want.
It can be opened in Word Pad.
The .lk file must contain the user name of the
Jedec followed by a space and your Jedec
name.
