Items to be set Set value
Explanation
Alignment Group IC Sets the component category.
Alignment Type P-TR 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 of the lead pitch 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 N
Sets the offset amount for the detection line in the
N direction.
Ruler Offset S
Sets the offset amount for the detection line in the
S direction.
Ruler Width
Lead Number : N
Sets the number of leads in the N direction.
Reflect LL.: N (mm)
Sets the lead length on the image.
Lead Width: N (mm)
Sets the width of the lead.
Lead Pitch: N (mm)
Sets the pitch in the N direction. (Set to 0 when
there is only one lead.)
Lead Number : S
Sets the number of leads in the S direction.
Reflect LL.: S (mm)
Sets the lead length on the image.
Lead Width: S (mm)
Sets the width of the lead.
Lead Pitch: S (mm)
Sets the pitch in the S direction. (Set to 0 when
there is only one lead.)
Table 17
This is the recognition mode for power transistors with leads in the N and S directions. It can
be used not only for power transistors, but also for recognition of any components whose
upper and lower lead width and lead lengths are different.
The number of the lead, lead pitch, lead width and lead length can be defined separately for
the N and S directions. Though the upper and lower directions do not need to be symmetrical,
the left and right directions must be symmetrical.

[Recognition check items ]
Items Yes / No Notes
Body Size May exist Only the outer edge dimension Y is checked.
(Note 1)
Lead pitch Yes The pitch in the direction with one lead is not checked.
Lead width
No
Reflect LL No
Find Pos Yes
Checks the lead tip position using [outer edge
dimension Y x tolerance] as check range.
(Note 2)
Table 18
Note:
1. This function performs a check only when the check function is validated in the
application software. (Some versions are not equipped with this function.)
2. See “Appendix 4. Lead position check” for the details of the “Lead position check”
function.
Table 19 shows the example of actual settings and the recognition results.

As shown in
Figure 21
, the Ruler Offset in the N direction is set so that sections where the
leads are not chamfered are detected.
