Perform a step test.
1. Press the [Step] button at the "Tuning" tab to perform a test for the created step.
2. When the test result appears, press the [End] button. When doing so, there is no problem if the test
result is "NG".
5
Press the [Detail] button.
The "Inspect result" dialog box opens. Press the [Auto Calculation] button. The following detection
conditions parameter and judgment condition parameter items are set automatically.
Detection conditions parameter
Min Area (%)
"20" is set.
Minimum Detectable Size X, Y (mm)
A value 70% of the minimum detection width is set.
Judgment conditions parameters
Min distance (mm)
A value 90% of the recognition distance is set. An NG result is judged if less than the value set here.
Max distance (mm)
A value 110% of the recognition distance is set. An NG result is judged if greater than the value set
here.

Perform a step test again.
1. Press the [Step] button at the "Tuning" tab again to perform a step test.
2. Take a note of and check the detection data, and then press the [End] button.

Threshold No. : Threshold No. used for inspection
dx =, dy = : Amount that the step frame center deviates from the detection area center
Area = : This is the detection object distance. (Unit: mm)
3. If the test result is not judged correctly, review all parameters while referring to the detection data

NOTE
Paste a completed step to a missing part position and ensure that an NG result is returned. If judged incorrectly,
review the minimum or maximum distance.

1.3 Polarity Check
This inspection status is used if inspecting the parts mounting angle by recognizing polarity marks on IC partss
and so on.
TIP

• Byselectingcharacterrecognitionfortheinspectionstatus,selecting"NON"for"AcceptableRotation"inthe
judgment parameters, and then performing an inspection, the parts mounting angle can be inspected.

Make a "step" setting.
1. Create a step frame.
When creating a step frame for a circular mark, create a frame which is slightly smaller than the
circumference of the circle.
2. Open the "Basic" tab, and set the "Status" in the basic parameters to "Polarity Check".
3. Open the "LIGHT" tab, and set the light sampling type and threshold value in the lighting parameters
so that polarity marks are shown in red.
Sampling light type reference: Color
Status (Inspection mode)
Polarity Check
Set to "Polarity Check".

Set the "Detect" parameters.
Open the "Detect" tab and set the following parameters.
"Detect" parameters
Status: Polarity Check
24412-P6-00
Minimum Detectable Size X, Y (mm)
Sets the minimum size for the object to be inspected. Set default values of X = 0.06, and Y = 0.06. (An
appropriate value is set at Step 5.)

Set the "Judge" parameters.
Open the "Judge" tab and set the following parameters.
"Judge" parameters
Status: Polarity Check
24413-P6-00
Offset Limit N, S, E, W (mm)
An NG result is judged if the positional displacement in the up, down, left, or right directions exceeds this
value.
Ref. value SKIP
Min Area (%)
If the ratio of the detected area to the standard area is smaller than the value set here, then an NG
occurs.
Ref. value 40%
Max Area (%)
An NG result is judged if the ratio relative to the standard area for the detected area exceeds this
value.
Ref. value 100%

Perform a step test.
1. Press the [Step] button at the "Tuning" tab to perform a test for the created step.
2. When the test result appears, press the [End] button. When doing so, there is no problem if the test
result is "NG".
5
Press the [Detail] button.
The "Inspect result" dialog box opens. Press the [Auto Calculation] button. The following items in the
detection conditions parameters are set automatically.
Minimum Detectable Size X
A value 50% of the recognized X width is set.
Minimum Detectable Size Y
A value 50% of the recognized Y width is set.
6
Change the step frame size.
Change "Step Size X, Y (mm)" in the basic parameters. To avoid a "permissible deviation error" due to the
influence of the polarity mark surroundings, enter a value to 1.5 to 2 times the polarity mark size.
7
Change the "Offset Limit" in the judgment conditions parameters.
Set "Offset Limit N, S, E, W (mm)" to "SKIP".
