Multi-zones are used for

components that are bigger

than the camera field of view.

That is why even if only one

zone is visualized on the tst

file, several images are taken

into account during the exe-

cutions of the associated pro-

cesses. Multi-zones are

automatically created if very

large components are

present on the panel via the

Creation zones menu or via

the creation of the tst file.

The multi-zones are defined by a continuous white line.

4.8.3.3 Centered zones

Centered zones have been defined in order to center a component in the camera field of

view and in order to avoid the problems linked to the camera optical aberrations.

Centered zones get the same

properties as standard zones.

The only difference is that

these zones are by default

protected against moving and

destruction at their creation.

Centered zones allow one

centered jedec for one zone

plus others components with

different jedecs.

Centered zones are defined by a dotted mauve line

when the moving and destruction protection are set,

with a continuous mauve line when the protections

are removed.

4.8.3.4 Joker zones

Multi-zones cannot

be manually created.

Pay attention to the

fact that the jedec

codification is not

displayed on the

creation window of

the centered zone

but it is saved in the

zone.dsc file.

The Joker zones have been defined in order to get additional lightings for some compo-

nents or type of components which generate problems with the inspection.

The aim is to affect one specific zone Joker zone to one family of component to be able

to re-use this configuration in different tst. files.

Joker zones can be identified

by the Linked Jedec name

that represents one or sever-

al jedecs codifications struc-

turing the name of the zone

and the “name” of the layer,

these jedecs have exactly the

same light levels settings.

Joker zones get the same

properties as centered zones.

Joker zones allow for one je-

dec specific light levels.

Joker zones are centered by

default, meaning that only the

selected jedec belongs to this

zone and this particular com-

ponent linked the jedec is

centered in the zone.

Update file button (activated when a level tab is selected) allows the update of the

zones.dsc file following to the user modifications concerning light levels settings (the up-

date is not automatic and concern only the selected tab).

Joker zones are defined by a dotted blue line when the

moving and destruction protection are set, with a con-

tinuous blue line when the protections are removed

(description board below).

If the joker zone is not centered on the jedec associated, only the components

with the same jedec or different

jedecs present in the zone .dsc file needing

the same light levels

and not centered, are affected to this zone.

4.8.4 TST file edition

During tst file opening some checks are done in order to find out the jedecs contained in the

zones.dsc file and present in the tst file.

4.8.4.1 Zones layers

After the tst file opening, click on

Dysplay zones

button in order to display the zones already

associated with the tst file, if the operator unselect the menu, the zones will be no more dislayed.

This selection will also display the zones layers win-

dow.

The standard zones and centered zones are re-

grouped into one layer, same for Multi-zones.

Joker zones are dispatched into several layers fol-

lowing their light levels settings.

By clicking on the icon Eye the user can hide or dis-

play the zones linked to the layer (in order to show

only theses zones).

4.8.4.2 Automatic zones creation

After the tst file opening, in Edit menu, go to Board sub menu to create automatically,

re-create or delete the different zones. The menus allowing zones creation are:

4.8.4.3 Automatic centered zones creation

The menu Create zones allows the creation and the management of zones.dsc file con-

cerning the jedecs associated to centered zones.

1. Select Create zones in the pulldown menu. A warning

message will appear expecting a confirmation or not of

the zones creation.

2. Click on OK button. A list of jedecs already defined for

centered zone appears.

If there are some jedecs cor-

responding, an information

message will appear. This

message will appear each

time the user will modify the

zones.dsc file.

The user can check the box in order to avoid the message, he must save the tst file to

keep this modification.

Menu Description

Create zones Zones creation menu will first delete all the not protected zones like standard zones then

re-create them and will continue with centered zones and multi-zones creation.

Create Joker

zones

Zones creation menu will create Joker zones.

This menu choice will not delete the existing Joker zones, but will create Joker zones

over existing ones.

If the menu Executable component is checked, only the executables compo-

nents are attached to zones, if not, all components of the tst file are attached.

The contextual menu allowing zones creations is accessible by clicking with the

right mouse button on the panel in the .tst file.
