• Leads on only one side
• Leads on two opposite sides
• Leads on two adjacent sides
• Leads on three sides
• Leads on four sides
The center moves depending on the lead positions, lead lengths, and lead widths.
For parts with leads on three sides, the part center is defined as the point of intersection of
the center line from the outer-most points top to bottom and the center line from the outer-
most points left to right. As a result, the part center required for placement differs from the
actual placing position.

4.6.2 NXT vision types
This section provides a list of the vision types for the NXT and an explanation of the
processing method used for each type. It is possible to use older vision types for other Fuji
machines in some cases. When making part data, if the parts are to be shared between
the NXT and other Fuji machines, use the old vision types in the “generic” section and enter
overrides for the NXT vision type when necessary. Refer to 4.7 "Compatibility with Existing
Part Data" for details.
Select the appropriate vision type from the following list of algorithms.
