Items to be set Set value Explanation
Alignment Group Chip Sets the component category.
Alignment Type Cylinder Sets the component type.
Comp. Threshold Sets the binarization level.
Comp. Tolerance Specifies the shape tolerance as a percentage.
Search Area (mm) Sets the range of the detection.
Body Diameter Sets the size of the outer edge.
Body Size Z (mm) Sets the size of the outer edge.

Items to be set Set value
Explanation
Alignment Group Chip Sets the component category.
Alignment Type Sp.Chip Sets the component type.
Comp. Threshold
Sets the detection level difference for
lead detection
.
(See “Appendix 2. Detection level
differences used to detect leads (threshold
value)”.)
Comp. Tolerance Specifies the tolerance as a percentage.
Search Area (mm) Sets the range of the detection.
Body Size X (mm) Sets the size of the outer edge.
Body Size Y (mm) Sets the size of the outer edge.
Body Size Z (mm) Sets the size of the outer edge.
Cntr. Offset X (mm)
Sets the offset amount in the X direction
from the center position.
Cntr. Offset Y (mm)
Sets the offset amount in the Y direction
from the center position.
Cntr. Offset R (mm)
Sets the offset amount of the angle of
rotation.
Ruler Offset
Sets the offset amount of the detection
line.
Common
Data
Lead Length Sets the lead width.
Table 84

IM-SMT-VSNDIC-0002-000
Not only the size of the outer edge, but also the lead width can be set. This mode is used
when the size of the outer edge and the lead width are different.
In addition to the outer edge sizes, the amount of offset from the center position can be set.
This makes it possible to offset the center of mounting position.

[Recognition check items]
Items Yes / No Notes
Body Size May exist Only Body Size Y is checked
Lead pitch No
Lead width Yes
Lead length No
Lead position Yes
Checks whether the center of the detected lead tip is in
the range of Body Size Y x tolerance.

2.11.6. Small Chip
<<Items to be set for Small chips>>
Items to be set Set value
Explanation
Alignment Group Chip Sets the component category
Alignment Type
Small
Chip
Sets the component type
Comp. Threshold
Sets the detection level difference for lead detection
(See “Appendix 2. Detection level differences used to
detect leads (threshold value)”.)
Comp. Tolerance
Sets the shape tolerance as a percentage
Search Area (mm)
Sets the range for detection
Body Size X (mm)
Sets the outer edge size
Body Size Y (mm)
Sets the outer edge size
Body Size Z (mm)
Sets the outer edge size
Ruler Offset
Sets the offset amount for the detection line
Reflct LL
Sets the length of the electrode. (If 0.2mm is set, it is
the same setting as Standard chip.)
Align size X (mm)
Sets the size X recognized on the image.
Align size Y (mm)
Sets the size Y recognized on the image.
Table 86
This mode is used for the components smaller than 1005.
These components look smaller on the image compare to the actual size, which affects the
recognition. When recognizing these small components, the difference between the
recognized size and the actual component size become large, and the effect on recognition
becomes large accordingly. This mode is used to deal with the symptom.
