5.2.4.4 Procedure for creating general-purpose vision component data
5.2.4.4.1 Lead components (Element group/Element format)
This section describes the procedure for creating data on lead components
(multi-lead components).
1) Operation on the “Extended Vision” screen
- Select “Lead Component” on the “Component Type” combo box.
- Check the “Element group/Element format” check box in the “Define data
format” field.
- Click the <Add> button on the “Element Group List”.
2) Operation on the “Element Group” screen
Define an element group on this screen.
An element group is composed of components whose lead size and pitch are the
same.
See Figure 5.2.4.4.1 for an example of a multi-lead component. The procedure
for creating data on this component is to be described below.

▼ Description
In the example below, four element groups are defined. The size and pitch of
leads of the first and third element groups are the same, while the direction and
position of leads of these groups are different from each another. The size and
pitch of leads of the second and fourth element groups are the same also, but
leads of these groups are not arrange continuously, so the lead pitch is not the
same. If the distance between these leads is an integral multiple of the specified
pitch, they can be defined as one element group that has an area having no lead.
However, we recommend that you define them as separate element groups.
To define the direction and position of the element group, specify the component
posture. In Figure 5.2.4.1.1, the direction of a component shown is normal. The
posture of multi-lead components is regulated from the top view.
