4.8 Zones creation

4.8.1 Zones presentation

Zones can be created automatically by the menu or via the creation of the .tst file or manually.

Zones will be created with defaults values that are defined in Default.ini file. Each zone can have

its own properties and its own light levels. A zone can be created on any components even if it

is not executable (to create zones on only executable ones a flag must be set in the menu).

Zones are associated and

regrouped into zones layers

displayed in a small window

when the Display zones

menu is selected. Zones

may have different colors

as shown opposite.

4.8.2 Zones.dsc file and default values

Zones.dsc file is a structured file. The file memorizes the characteristics of the joker zones like

Jedec codification, centering property, light level settings, same for the centered zones (Jedecs).

This file will be used and shared by all the tst files. Zones.dsc file content is displayed during the

automatic zones creation for centered and Joker zones.

Default values are kept in the Default.ini

file that can be acceeded by the user.

4.8.3 Type of zone

4.8.3.1 Standard zones

Standard zones can be created

on all the components except

very large ones that need multi-

zones. The user can check the

box

Propagate all light levels

he had modified light levels set-

tings. It will copy the 5 light levels

settings on all the standard zones

and multi-zones which are not

protected against

Light propa-

gation

. The

Default

button will

removed the light levels settings

modifications and set the default

ones that are defined in

De-

fault.ini

file.

Standard zones are defined by a continuous mauve line.

4.8.3.2 Multi-zones

By default, a standard zone is created without

any protections.

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.
