Check Pos
Z
Refers to the Z-axis height when checking whether the nozzle is mounted or not.
This is indicated as the distance from the PCB top surface to the end of the head
spindle 다.
Mirror
Refers to the position of the mirror axis when checking whether the nozzle is
mounted or not. This is indicated as degree.
Nozzle
Checks whether the nozzle is mounted or not by comparing the binary value of the
pixel of a certain area when the nozzle is mounted with that when the nozzle is not
mounted.
The certain area mentioned above is called the test area, which is displayed in box
form on the vision screen.
Offset X / Offset Y
When indicating the distance from the cross hair center of the vision screen to the
center of this rectangular box, i.e. test box in the Right-Down Coordinate System,
the distance in the X-axis direction is called Offset X and the distance in the Y-
axis direction is called Offset Y.
Count X / Count Y
The size of the test box in the X-axis direction is called Count X, and the size of
the test box in the Y-axis direction is called Count Y.
Light
When checking whether the nozzle is mounted or not using the fly camera, lighting
becomes a crucial factor in determining the binary value of the pixel in the test box
area.
Therefore, in order to check the lighting condition when examining whether the
Samsung Component Placer CP45FV Administrator’s Guide
nozzle is mounted or not using the fly camera, the area where the lighting condition is
checked must be setup.
This area is displayed in the form of a rectangular box on the vision screen.
Offset X / Offset Y
When indicating the distance from the cross hair center of the vision screen to the
center of this rectangular box, i.e. test box in the Right-Down Coordinate System,
the distance in the X-axis direction is called Offset X and the distance in the Y-
axis direction is called Offset Y.
Count X / Count Y
The size of the test box in the X-axis direction is called Count X, and the size of
the test box in the Y-axis direction is called Count Y.
When activating the <Test> button, the Offset / Count cell must be clicked.
The coordinate system in the following figure is obtained from the cross hair center of the
vision screen.

Threshold
Refers to the reference value for distinguishing the white pixel and black pixel when
calculating the binary pixel count. This has the value between 0 and 255. The default
is 100.
<Test> button
Sets the nozzle recognition condition and lighting condition by testing the binary
value of the pixel for the certain area (test box) that is set using the fly camera.
When the binary value of the pixel for the area that is used to check whether the
nozzle is mounted or not is below 30%, the nozzle is considered to be mounted. If the
value is above 30%, the nozzle is not considered to be mounted.
