Inspection status
1.12 Foreign object check
This inspection status is used to detect foreign objects such as solder balls.
1
Make a "step" setting.
1. Create a step frame.
2. Open the "Basic" tab, and set the "Status" in the basic parameters to "Foreign object".
Status (inspection mode)
Foreign Object
Set to "Foreign Object".

Set the "LIGHT" parameters.
1. Open the "LIGHT" tab and select "Luminance" at "Light Sampling Type".
2. Press the button to the right of the sampling light value field to open the sampling light list, select
"Lb" from the list, and then press the [OK] button.
3. Set "Use" for "Thresh 1", and use the threshold slide bar to set the lower limit to 100, and upper limit to
255.
"LIGHT" parameters
Status: Foreign Object
Opens a lighting list.
Set the upper and lower threshold values.

4. Press the [Detected] button in the button area, and verify that only solder balls or foreign objects are
red in the field-of-view screen. If only the target object fails to turn red, correct the sampling light or
threshold value.

Foreign Object Level
Set the difference in luminance level between objects to be detected as a foreign object and its
surroundings to a value from 0 to 255. Set to "20" at first.
Minimum Detectable Size X, Y (mm)
Enter the minimum detection size X and Y for objects to be detected as the target object. Set to a value
of approximately "0.1" at first.

Set the "Judge" parameters.
Open the "Judge" tab and set the following parameters.
"Judge" parameters
Status: Foreign Object
24451-P6-00
Judge Size Condition
Set whether to judge as an NG result if both the X and Y sizes of the detected foreign object are judged
to be NG, or to judge as an NG result when even one of the X or Y sizes is judged to be NG when
judging foreign object inspection.
Judge Size X Min. (mm)
An OK result is judged if the X direction size of the detected foreign object is less than this value.
Judge Size X Max. (mm)
An OK result is judged if the X direction size of the detected foreign object is greater than this value.
Judge Size Y Min. (mm)
An OK result is judged if the Y direction size of the detected foreign object is less than this value.
Judge Size Y Max. (mm)
An OK result is judged if the Y direction size of the detected foreign object is greater than this value.
