Part III Inspection Algorithm

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.

1.4.2 Parameter Setting

Figure 1-10 ColorXY

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.

Part III Inspection Algorithm

1.5 ChipMissing3

1.5.1 Inspection Overview

ChipMissing3 is the algorithm to inspect solder at either end of the chip component with TopLight and

SideLight used.

The brightness level of a solder is lower if a solder ﬁ llet is formed. The brightness level of a solder is

higher if a solder ﬁ llet is not formed, or a component is missing (refer to Figure 1-13).

ChipMissing3 is suitable for a chip missing inspection or solder inspection.

1.5.2 Parameter Setting

Figure 1-12 ChipMissing3

Parameter Description

Lighting Select SideLight.

Algorithm Select ChipMissing3.

SideLight Upper Level Upper limit of brightness level in OK range (SideLight).

TopLight Upper Level Upper limit of brightness level in OK range (TopLight).

Search Range[0-30] Enter 0.

Shift[V1-V8]

Enter the appropriate vector. Any value from V1 to V8 is available.

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

PAD Length Default is 30. Enter the bigger value to enlarge the inspection area.

Memorize to -

Upper, Lower Set the upper and lower limit of the OK range.

Sample Refer to Part III 1.5.4 Calculation of Sample Value.
