2.12.4. Special Quad
This is the recognition mode used for rectangular components. Squares can also be
recognized with this mode.
<< Items to be set for recognition of Sp Quads >>
Items to be set Set value Explanation
Alignment Group Special Sets the component category.
Alignment Type Sp. Quad Sets the component type.
Comp. Threshold
Sets the binarization level.
(If 0 is specified, the threshold is set
automatically.)
Comp. Tolerance
Specifies the shape tolerance 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.
Surface Type
Selects from reflect and non-reflect.
Selects reflect when the component
appears to be white and selects
non-reflect when it does not.
Cut Outer Noise Select from 0 through 7.
Cut Inner Noise Select from 0 through 7.
Noise Cut Order Selects from “Inner” or ”Outer”.
Lead Number N
When not performing line detection in
the N direction, this sets the value
other than 0.
Lead Number S
When not performing line detection in
the S direction, this sets the value other
than 0.
Lead Number E
When not performing line detection in
the E direction, this sets the value other
than 0.
Common
Data
Lead Number W
When not performing line detection in
the W direction, this sets the value
other than 0.

Table 104
Figure 126
As the component has leads in the N/S direction, the value “1” is set to “Lead Number N/S” in
order to avoid line detection in the N/S direction.
As a result, recognition is carried out only in the right/left (E/W) direction.
The following shows the recognition results of the actual component (trimmer capacitor).
Recognition was performed only in the left/right (W/E) direction for these components.
