P_pattern 11, 12
These are used for parts with leads that are attached to the body at both ends of the leads
and whose lead detection is not stable. The lead widths are checked and the results are
used to determine the part positioning.
• Type 11: The lead appears black and the outside circumference is white.
• Type 12: The lead appears white and the outside circumference is black.
Except for parts using vision type 151 and picked up by a mechanical chuck in the Y-
direction, these p_patterns can only be used for parts that have leads on two perpendicular
sides or more. However, if it is possible to detect either end of the lead in a stable manner,
it is recommended to select a different p_pattern (type: 13, 14, 15, 16) that matches the
processing conditions.
Furthermore, the information for the part positioning using the lead length is not acquired
so these types cannot be used for parts with leads on one side or two opposing sides only.
Example Target Parts
Type 11: TAB parts processed with backlighting.
Type 12: Parts with lead tips that poorly reflect using vision type 151 and a mechanical
chuck to pick the part in the Y-direction processed with frontlighting.

P_pattern 13, 14
Basically, these are the same as p_pattern types 3 and 4. The major difference is that with
these p_patterns, the outward pointing lead tip is not used for determining the part
positioning. The lead width detection results only are used to determine the part
positioning. The lead tip detection results are used only as reference data for internal vision
processing items.
• Type 13: The lead appears black and the outside circumference is white.
• Type 14: The lead appears white and the outside circumference is black.
It is only possible to use this for parts that have leads that are to be detected on two
perpendicular sides or more.
Furthermore, the information for the part positioning using the lead length is not acquired
so these types cannot be used for parts with leads on one side or two opposing sides only.
Example Target Parts
Type 13: QFP parts processed with backlighting.
Type 14: Black background and body parts (e.g., QFP) processed with frontlighting.

P_pattern 15, 16
Basically, these are the same as p_pattern types 5 and 6. The major difference is that with
these p_patterns, the inward pointing lead tip is not used for determining the part
positioning. The lead width detection results only are used to determine the part
positioning. The lead tip detection results are used only as reference data for internal vision
processing items.
• Type 15: The lead appears black and the outside circumference is white.
• Type 16: The lead appears white and the outside circumference is black.
It is only possible to use this for parts that have leads that are to be detected on two
perpendicular sides or more.
Furthermore, the information for the part positioning using the lead length is not acquired
so these types cannot be used for parts with leads on one side or two opposing sides only.
Example Target Parts
Type 15:Currently no example target part exists.
Type 16:Black background and body parts with orthogonal leads in the body (e.g., LCC)
processed with frontlighting.
