Body Size Y (mm) Sets the size of the outer edge.
Body Size Z (mm) Sets the size of the outer edge.
Ruler Offset Sets the offset amount for the detection line.
Ruler Width
Lead Number
Sets the number of leads on one side.
Lead Pitch (mm)
Sets the pitch.
Lead Width (mm)
Sets the width of the lead.
Reflect LL. (mm)

[Recognition check items ]
Items Yes / No Notes
Body Size May exist Only the “Body Size X” is checked.
(Note 1)
Lead pitch Yes
Lead width
May exist
Checks only when the lead width is more than 1.0mm.
(Note 2)
Reflect LL No
Find Pos May exist
Checks the lead tip position using [outer edge
dimension Y x tolerance] as check range.
(Note 3)
Table 23
Note:
1. This function performs a check only when the check function is validated in the
Application software. (Some versions may not be equipped with this function.)
2. “Lead width” check function may not be available for the old versions.
3. See “Appendix 4. Lead position check” for the details of the “Lead position check”
function.
The following is the example of actual setting and the recognition result.
