5.3 Skips edition
The skips can be edited once the .tst file
has been created.
Click on any of the skip symbols to ac-
cess to the Skip edition window.
5.3.1 Skip edition window
All the skip parameters are ac-
cessible from this window.
In Description (A) section, en-
ter the Skip type (by default:
X). The skip coordinates are
extracted from the CAD data of
the .vis file used to generate
the .tst file.
In Lighting (B) section, click
and move the cursors to modify
the brightness of your various
lighting types in order to obtain
the most contrasted image.
In Window (C) section, define a search area to find the skip.
These parameters form the search window around the CAD coordinates of the skip, defining the
zone in which Vision 2007 will locate the skip. All the dimensions are in µm.
This lighting is specific
to skips: it is used dur-
ing board inspection.
Adjusting skip lighting
You must always adjust skip lighting to have the best possible image.
Move the camera above the skip until you can see the image of the skip when you adjust its
lighting.
Adjust the skip lighting to obtain a contrasted image of the skip.
The search window is defined in the Vi-Pro parameters if you use a model in the library
to find a skip.

5.3.2 Skip inspection
The skip inspection is settable in the Skip edition window.
If the Skip board when skip found box is ticked, the board is skipped when the skip process-
ing returns OK.
If the Skip board when skip found box is not ticked, the board is skipped when the skip pro-
cessing returns MISSING.
5.3.2.1 Fiducial finder tool for skip
FIDUCIAL FINDER is the easiest tool to find a circular and full skip.
Definition of the skip type:
LIGHT (white circle on a black background),
DARK (black circle on a white background).
Skip diameter (in µm).
5.3.2.2 Blob tool for skip
BLOB is the tool used to identify non-round skips.
Definition of the skip type:
LIGHT (white circle on a black background),
DARK (black circle on a white background).
The threshold specification is used to binarise the image (black & white).
The minimum surface (in pixels) of the identifiable skip.
5.3.2.3 Skip identification in library
If the skip is not circular, you
can program a model in the li-
brary.
This model must be called
SKIP_X (according to the
skip type).
The light level used will be
the one defined in the Skip
edition window.
You can program skips in the
library exactly like a compo-
nent mode (several tools,
equations…).
If you use the Vi-Pro
treatment, the Skip
search window will
be the one defined
in the Vi-Pro tab.

5.3.2.4 Skip propagation
In the Skip edition window, tick Propagate Skips to extend all the parameters of this
skip to all the skips.
Click OK to validate parameter changes and / or propagate the profile.
Click Cancel to abort and return to the main window of Vision 2007.
If you choose to propagate parameters, a message will ask you to confirm the propaga-
tion of this skip profile to all the other skips of the same type.
5.3.3 Skip execution
The skip execution is settable in the .tst file configuration (computing tab). Check skip before
fiducial = 0.
If the box is ticked, the skips will be executed before the fiducials. In this case there is no re-
alignment, so be, sure that your skips are not too close to each other.
If the box is not ticked, the skips will be executed after the fiducials. In this case the skips re-
alignment is as follow.
Realignment with fiducials
1st case:
The skip is inside the board and you have board fiducials:
Realignment with the board fiducials.
2nd case:
The skip is outside the board and you have panel fiducials:
Realignment with the panel fiducials.
3rd case:
The skip is outside a board and you have board fiducials:
No realignment.
