Figure 49
As shown in Figure 49
,
this recognition mode is used when there is a gap in the row of leads.
It is possible to define the components that have leads not only in two directions, but also in
one direction, three direction and four directions.
The numbers of the leads that start and end the gap are specified as the gap start/end
parameters.
In the example of
Figure 49,
the values would be as follows:
Lead Number: 9
Off Lead start: 5
Off Lead end: 5
When performing recognition of the components that have leads in two directions (E-W),
the recognition method is the same as that of SOJs. The others are the same as connector
component recognition.
[Recognition check items]
Items Yes / No Notes
Body Size No
Lead pitch Yes The pitch in the direction with one lead is not checked.
Lead width May exist
Checks only when the lead width is more than 1.0mm.
(Note 1)
Reflect LL No
Find Pos No

Note:
“Lead width” check may not be available for some old software versions.

This mode is applicable not only for the components with the missing leads as above
mentioned, but also the tips that have leads for heat radiation as shown below. (It ignores the
leads for heat radiation.)
