1. Std. Chip
1.1. Chamfer Lead
Suitable for chip components where part of a corner is missing.
Particular parameter
Chamfer Direction
Set a direction of the chamfering.
Check Many
Adsorption
It confirms whether excessive components exist. When the “Check” is
specified, it becomes an error if excessive edges exist around the detected
component.
*Cannot use this parameter on VGOS V2.xx and YGOS V2.xx.
1.2. Check Lead Brightness
Suitable for standard chip components.
Although recognition is the same as for "Normal", more detailed check conditions
can be specified. If the "Comp. Intensity" is specified (automatically specified at
recognition tests), the electrode area brightness is checked to determine if a
component is present or absent.
Particular parameters
Check Many
Adsorption
It confirms whether excessive components exist. When the “Check” is specified,
it becomes an error if excessive edges exist around the detected component.
Comp. Intensity The minimum luminosity of the component electrode section is specified. When
the average luminosity of an electrode section is darker than the value set up
here, it becomes an error. (It is the same function as the same name parameter
in a recognition tab at the normal algorithm.)
Check Algorithm
The prevention function of nozzle incorrect recognition is specified.
Ａ ： Lead
Brightness
Only the above-mentioned “Comp. Intensity” function is
performed.
Ａ ＆
Symmetry
The symmetry on the lengthwise direction central line of
component is evaluated.
Ａ ＆
Difference
The variation in the luminosity on the transverse direction
central line of component is evaluated.
Trapezoid
Tolerance (%)
The degree of trapezoid permissible as good is specified.
If {(difference of up-and-down electrode width) / (electrode width of the narrower
one)} is larger than the value set up here, it becomes an error. When 0 is set up,
this check is not performed.

1.3. Check Direction
Suitable for identifying a chip component's direction.
A direction judgment is made by comparing the average brightness of
the specified circle area with a 180 degrees opposing circle area.
Suitable where a polarity mark, etc., exists on the recognition face.
Particular parameters
Check Type When it is expected that the brightness of the specified circle will be brighter
than the brightness of a rotation symmetry position, “White” is specified. Else
“Black” is specified.
Check Direction The direction at which a direction judging is performed is specified.
In distinguishing 0 and 180 degrees, “2 Angle” is specified. In distinguishing 0,
90, 180, and 270 degrees, “4 Angle” is specified.
Min. Brightness
Difference
The difference in the average brightness of detection circles being checked in
order to differentiate the directions must be larger than this value, or an error will
occur. If 0, 50 will be set.
Direction Mark
Diameter (mm)
The diameter of the circle where brightness is measured is specified.
Direction Mark
Center X
Direction Mark
Center Y
The center position of the circle where brightness is measured is specified.
(Origin: The component center)
Check Many
Adsorption
It confirms whether excessive components exist. When the “Check” is specified,
it becomes an error if excessive edges exist around the detected component.
*Cannot use this parameter on VGOS V2.xx and YGOS V2.xx.

1.4. Check Center Brightness
Suitable for distinguishing between the top and bottom faces of chip
components.
The top/bottom judgment is made by measuring the average
brightness at the component center (circle area).
Particular parameters
Check
Threshold
The average brightness of the measurement circle is compared with the value
set up here, and turnover judging is performed.
Check Diameter
(mm)
The diameter of the measurement circle is specified.
NG Type An error judging condition is specified. In the case of “Black”, it will become an
error if the average brightness of the measurement circle is darker than the
“Check Threshold”. In the case of “White”, it becomes the contrary.
Check Many
Adsorption
It confirms whether excessive components exist. When the “Check” is specified,
it becomes an error if excessive edges exist around the detected component.
*Cannot use this parameter on VGOS V2.xx and YGOS V2.xx.
1.5. Retry Lead Center Search
Suitable for chip shape components where the west to east direction edge position is
unclear.
Particular parameter
Angle Correction
Under the influence of the fine projection on the detecting line, when angle
accuracy is not good, if it turns “On”, angle accuracy will be improved.
Check Many
Adsorption
It confirms whether excessive components exist. When the “Check” is specified,
it becomes an error if excessive edges exist around the detected component.
*Cannot use this parameter on VGOS V2.xx and YGOS V2.xx.
