As shown in
Figure 12
, the components whose “Body size X” and the “Lead width” are different
can be defined. The upper/lower and left/right leads need to be symmetrical.
Chip recognition is used as the recognition method.

<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 the lead tip position using [Body Size
Y x tolerance] as the check range.
* Please refer to “Appendix 4. Lead position check”
for the details of “Lead position check” function.

In the recognition result shown in
Figure 13
, “sizeh” is displayed as the average value between
the upper and lower lead width. Special recognition is available for recognizing the 2-pin
components. Please refer to “2.11.6. Special recognition of chip components (standard
chips, MELF chips, special chips)
” for the details.
