• Sequence of Polarity Determination

(2) Inspection method
Select one of the following options to specify how many places should
be inspected for polarity determination.
4-Point Insp : Select this to inspect the four places rotated in
increments of 90°, based on the center of the
component.
Select this for a square component.
2-Point Insp : Select this to inspect the two places rotated by 180°,
based on the center of the component.
Select this for a rectangular component.

4.2 Data Explanation (B02_15)
Top View of Component (Polarity Different by 180°)
Positioning is performed for
polarity determination.
When "4-Point Insp" is selected,
the machine inspects four places
and determines whether or not
the component has a polarity.
When "2-Point Insp" is selected,
the machine inspects two sym-
metrical places and determines
whether or not the component
has a polarity.
When "Enable (Discard)" is
selected in the "Polarity detn"
text box, the processing is
regarded as a recognition NG
(No Good). When "Enable
(Placement)" is selected, the
recognition processing is
re-executed at the determined
angle.

(3) Polarity position X [mm], Y [mm]
Set the distances between the centers of the mold and the inspection
range.
Fig. 28
To set parameters in these text boxes, "Enable (Discard)" or "Enable
(Placement)" must be selected in the "Polarity detn" text box.
(4) Inspection range [mm]
Specify the range to be inspected.
Fig. 29
(a) Set a parameter as an inspection range such that the range having
high contrast is narrowed.
The threshold levels in the inspection range will increase or
decrease, making it easy to determine the polarity.
(b) To set a parameter in this text box, "Enable (Discard)" or "Enable
(Placement)" must be selected in the "Polarity detn" text box.
