1.9.6 Setting Procedure of Average (SOP)

Step1: Select a lighting that displays a polarity visually clear from the Lighting drop-down list.

Step2: Change the algorithm of Polarity to Average.

Step3: If the polarity mark is circle, change the inspection window shape to circle. Press Option in the

right side of Algorithm. Check Use non-rectangle window and Circle Window and press OK.

Step4: Adjust inspection window size to match with a polarity mark.

CAUTION

Change the lighting if there is no difference between polarity and component body

with default lighting.

Step5: Enter 255 in the Upper ﬁ eld, 0 in the Lower ﬁ eld, and M1 in the Memorize to ﬁ eld.

Step6: Enter the appropriate vector into the Shift ﬁ eld by selecting from V1 to V8 according to the

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

Step7: Select the Average inspection window. Right-click and select Point-Symmetric Copy.

Step8: Enter M2 in the Memorize to ﬁ eld of the inspection window which is made on Step7.

Step9: Select the inspection window which is made on Step7. Right-click and select Copy Window.

Step10: Change the algorithm of the inspection window which is made on Step9 to Mem1-Mem2.

Step11: If brightness level of a polarity mark is higher than brightness level of the component body,

enter 255 in the Upper ﬁ eld and 1 in the Lower ﬁ eld. If brightness level of a polarity mark is

lower than brightness level of the component body, enter -1 in the Upper ﬁ eld and -255 in

the Lower ﬁ eld.

Step12: Enter M1 in the Memory1 ﬁ eld and M2 in the Memory2 ﬁ eld.

Step13: Press Inspect. Make sure that the inspection is completed properly.

1.9.7 Setting Procedure of Average (QFP)

Step1: Refer to Step1 to 6 of Part III 1.9.6 Setting Procedure of Average (SOP).

Step2: Select the Average inspection window. Right-click and select X-Symmetric Copy.

Step3: Select two Average inspection windows by pressing

Right-click and select Y-Symmetric Copy.

Step4: Change the Memorize to value of the Average inspection windows. Enter M2, M3, or M4

in the Memorize to ﬁ eld of the inspection windows which are made in Step2 and Step3.

Step5: Select the inspection windows which are made in Step2 and Step3.

Right-click and select Copy Window.

Step6: Change the algorithm of the inspection windows which are made in Step5 to Mem1-Mem2.

Step7: Select the inspection windows which are made in Step5. Right-click and select Copy Window.

Repeat the same procedure twice to make two windows.

Step8: Change the Memory2 value of the Mem1-Mem2 inspection window. Enter M2, M3, or M4

in the Memory2 ﬁ elds of the inspection windows which are made on Step7.

Step9: Change the Upper ﬁ eld and Lower ﬁ eld of Mem1-Mem2. If brightness level of a polarity

mark is higher than brightness level of the component body, enter 255 in the Upper ﬁ eld

and 1 in the Lower ﬁ eld. If brightness level of a polarity mark is lower than brightness level

of the component body, enter -1 in the Upper ﬁ eld and -255 in the Lower ﬁ eld.

Step10: Press Inspect. Make sure that the inspection is completed properly.

1.10 Diagonally

1.10.1 Inspection Overview

Diagonally is the algorithm to inspect the average luminance of the inspection windows which are

located on symmetrical positions from the center of component.

Diagonally is suitable for polarity inspection of IC components.

1.10.2 Parameter Setting

Figure 1-29 Diagonally

Parameter Description

Lighting Select a lighting that displays a polarity visually clear.

Algorithm Select Diagonally.

Win Setting[1-3] Set the number of the windows to be compared.

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.

Memorize to -

Upper, Lower

If brightness level of polarity is higher than brightness level of component body, enter 255

in the Upper ﬁ eld and 1 in the Lower ﬁ eld. If brightness level of polarity is lower than

brightness level of component body, enter -1 in the Upper ﬁ eld and -255 in the Lower ﬁ eld.

Sample

If 1 is entered in Win setting, the brightness level difference between the window

and the window on the point-symmetric point will be calculated and its result

becomes the sample value.

If 2 is entered, in addition to operations of 1, the brightness level difference between

the window and the window at the center point on the component will also be

calculated. Two brightness level difference values are compared and the bigger one

becomes the sample value.

If 3 is entered, in addition to operations of 1, the brightness level difference between

the window which the setting is applied and the window on the line-symmetric point

will be calculated. Three brightness level difference values are compared and the

biggest one becomes the sample value.
