Inspection status Item Details
Shape Check
Offset Limit N - W (mm) Set based on the parts size and pattern design.
Inspection Shape
• Size
Performs inspection by comparing the recognition area dimensions with
step dimensions.
• Circularity (roundness)
Inspects how much the detection area contour deviates from perfect
roundness.
• Convexity
Inspects the smoothness of the detection area contour.
• Aspect ratio
Inspects the percentage of the detection object vertical length relative to
the horizontal length (horizontal = 100%).
Min Match Ratio (%) Enter the minimum match ratio for OK parts.
Max Match Ratio (%) Enter the maximum match ratio for OK parts.
Tolerance X, Y (mm)
These settings are valid for the size selected at "Size". The result will be OK
if the maximum dimension of the recognition area is within the dimension for
which the tolerance has been increased or decreased for the step size.
Code Recognition
Algorithm Type Selects the code type from "Unset", "QRcode", "D-matrix", or "Barcode".
Start Data Column
Specifies the starting digits used as the ID code from the extracted character
string.
End Data Column
Specifies the ending digits used as the ID code from the extracted character
string.
Cell Number Specifies the size of the extracted characters.
Foreign Object Judge Size Condition
• Two-Side-Size
An NG result occurs if both the object size X and Y directions are NG.
• One-Side-Size
An NG result occurs if either the object size X or Y directions is NG.
Ball Joint Check
Judge Size X, Y Min. Sets the minimum size for judging foreign objects.
Judge Size X, Y Max. Sets the maximum size for judging foreign objects.
Std Area (mm
2
)
This is calculated automatically from the pad diameter based on the original
ball joint area.
Ball Radius (mm)
This is calculated automatically from the pad diameter based on the original
ball joint area.
Position Check
Sets the allowable displacement from the center of the step to the center of
the recognition area.
Void Check
Max Accept Size X, Y
(mm)
This is the maximum allowable void X direction size relative to the detected
void.
Max Void Num. Sets the number of allowable detected voids.
Max Void Occupancy (%)
Sets the allowable occupancy rate for the area of all detected voids relative
to the standard area.
[OCR Reg.] button
Registers an original character font as the character recognition font for each user. For details on the character registration
method, see section 2.2, "Registering user characters", in this chapter.
[All Set] button
Pressing this button sets the selected displacement value for other directions also.

OK jump
Specify the step No. to be inspected next when the judgment result is
"OK".

Specify the step No. to be inspected next when the judgment result is
"NG".
NG Reason
Enter the NG (fail) reason to display during automatic inspection when the
judgment result is "NG".

Local Fiducail No. Sets the local Fid No.
Local BadMark No. Sets the local Bad No.
Mask Type
• Disable
Does not perform inspection mask function.
• Include
Always detects areas enclosed with a mask.
• Exclude
Does not include areas enclosed by mask in the inspection.
For details, see section 2.3, "Mask function", in this manual.
Mask Center Offset
X(mm)
Sets the X offset amount from the step center position to the mask center
position.
Mask Center Offset
Y(mm)
Sets the Y offset amount from the step center position to the mask center
position.
Mask Size X(mm) Sets the inspection mask X direction size.
Mask Size Y(mm) Sets the inspection mask Y direction size.
Ng image Out Sets the lighting when sent to the Repair Station (option).
Polarity Check Inspect Only First Parts
This setting can only be specified for "Character Recognition" and
"Electrode Check".
Inspection steps set to "Enable" are only inspected on the first board after
reading the inspection program.
Position Align
Correct Start Step Specifies the first step No. in the range subject to alignment.
Correct End Step Specifies the last step No. in the range subject to alignment.
[Mask Teach] button
Moves the mask area and changes the size of it. For details on operation, refer to section 2.3, "Mask function", in this
chapter.

2.1 Recognition method (based on light sampling type)
There are four methods available for recognizing inspection objects in order to perform inspection. Those
methods are luminance, color, shape, and X-ray. Select the image to be used for inspection, and then set the
threshold value to show the object to be inspected in red.
2.1.1 Luminance
Samples detection objects in region of specified luminance, and uses them as the object of inspection. Open
the "LIGHT" tab and select "Luminance" for the "Light Sampling Type".

Selects the sampling light.
Sampling light is the lighting used for inspection. Use the following procedure to select the sampling
light.
1. Press the [Light Detail] button to open the "Luminance" screen.
2. Press the [Sampling Light] button to open a sampling light type screen, and select up to two images
that show the inspection object with good contrast. The name of the selected images and
composite image of the selected images appears in the lower right. This image is used for inspection.
3. Press the [OK] button to save the settings.
