Table 25
Note:
The parameters other than those shown in
Table 25
are not used, and should be set to 0.
1) Special 1: This is the same recognition method as SOJ recognition. (SOJ recognition
should be used in order to run this mode.)
This mode improves the recognition rate by checking the positional relations
between the leads and extracting the combination best fits the component
definition when detecting the end leads.
2) Special 2: Not supported
3) Special 3: Not supported
4) Special 4: Not supported
5) Special 5: SOP upside-down judgment (LeadPitch)
This compares the lead pitches at the tip and root of the lead in order to check
the reversed component.
In order to set the inner detection line, the lead length is set to a length slightly
longer than the normal value. (This should be set so that the detection line
extends to the lead section.) This recognition method is available only when
using a single camera.
When using a multi-camera, it is impossible to perform recognition of the
leads aligned in the E/W direction.
If this method is being used, the leads should be aligned in N/S direction
before carrying out the recognition.
