Part III Inspection Algorithm

1.3.3 Setting Procedure

Step1: Select SideLignt from the Lighting drop-down list.

Step2: The Adjust window can be scaled to any size by adjusting the yellow square points on the corners

of the colored part of the chip. The window position should be adjusted in the Area window.

CAUTION

Do not move the Adjust window position by mouse-dragging.

Step3: Select two places and extract the colors.

Component RGB values are displayed in the graph.

By left-clicking with pressing , it is displayed on the left of the graph.

By left-clicking with pressing , it is displayed on the right of the graph.

NOTE

In order to expand the OK range, select one from dark colors and the other from

light colors.

Step4: Enter V1 in the Memorize to ﬁ eld.

Step5: Press Inspect.

If the search is successful, the pink window surrounding the component’s body appears.

NOTE

A value in Sample shows amount of misalignments. If the sample value is out of the

OK range, adjust the Area window position and re-check the Sample value.

1.4 ColorXY

1.4.1 Inspection Overview

ColorXY is the algorithm to inspect the color of the component.

ColorXY calculates average color of the inspection window and display red x marking at the graph in

the lower right side of the dialog.

The average color of the area which is to be OK and the average color of the area which is NG are

displayed in the graph. Compare these two average colors and set the borderline between them.

ColorXY is suitable for missing, misalignment, and polarity inspection of the chip component by using

colors.

Parameter Description

Lighting Select SideLight.

Algorithm Select ColorXY.

X1, Y1, X2, Y2 This ﬁ eld is automatically ﬁ lled when the blue borderline is moved.

Shift[V1-V8]

Enter an appropriate vector by selecting from V1 to V8 according to the vector

used in the Memorize to ﬁ eld in the Adjust window.

Memorize to -

Upper, Lower

If the average color of the area which is to be OK is in the left side of the blue

borderline, enter 255 in the Upper ﬁ eld and 0 in the Lower ﬁ eld. If the average

color of the area which is to be OK color is in the right side of the blue borderline,

enter 0 in the Upper ﬁ eld and -255 in the Lower ﬁ eld.

Sample Shows distance of x marking to blue borderline.

The graph in the lower

right side of the dialog

Average color in the window is displayed as red x marking. Green x marking is the

average color of other components which are sharing the same library. The

borderline can be moved by adjusting the yellow square points at the either end of

the blue borderline.

1.4.3 Setting Procedure

Step1: Select SideLignt from the Lighting drop-down list.

Step2: Make sure of the OK area’s average color. Adjust the window size smaller and make sure

of the x marking distribution in the graph in the lower right side of the dialog. The x marking

position is changed according to the window position.

Step3: Make sure of the NG area’s average color. Adjust the window size smaller and make sure

of the x marking distribution in the graph in the lower right side of the dialog. x marking

position is changed according to the window position.

Step4: Set an inspection window on the component.

Step5: Set the borderline between the position of the x marking if the window is in OK area and the

position of the x marking if the window is in NG area.

Step6: If the average color of the area which is to be OK is in the left side of the blue borderline, enter 255

in the Upper ﬁ eld and 0 in the Lower ﬁ eld. If the average color of the area which is to be OK color

is in the right side of the blue borderline, enter 0 in the Upper ﬁ eld and -255 in the Lower ﬁ eld.

Step7: Enter the appropriate vector into the Shift ﬁ eld. Any value from V1 to V8 is available.

Select the vector according to the Memorize to ﬁ eld of the Adjust window.

Step8: Press Inspect. Make sure that the inspection is completed properly.

NOTE

Sample value is the distance of x marking to blue borderline.
