1.10.3 Setting Procedure of Shift Inspection

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

Step2: Adjust the Diagonally inspection window position to surround the polarity mark.

Step4: If the brightness level of the polarity mark is higher than the brightness level of the component

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

polarity mark is lower than the brightness level of the component body, enter -1 in the

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

Step5: Enter the appropriate vector into the Shift ﬁ eld by selecting from V1 to V8 according to the

vector used in Memorize to in the Adjust window.

Step6: Press Inspect. Make sure that the inspection is completed properly.

1.11 Black/White

1.11.1 Inspection Overview

Black/White is the algorithm to inspect the percentage of the speciﬁ ed brightness level in the

inspection window.

If the percentage of the speciﬁ ed level exceeds a certain value, the result will be OK.

Black/White is suitable for solder inspection of chip components.

1.11.2 Parameter Setting

Figure 1-32 Black/White

Parameter Description

Lighting

Select TopLight to inspect solder paste.

Algorithm Select Black/White.

Upper Level[0-255],

Lower Level[0-255]

Calculates a value intermediate between OK sample value and NG sample

value. If OK sample value is smaller than NG sample value, enter intermediate

value in Upper Level ﬁ eld and 0 in Lower Level ﬁ eld. If NG sample value is

smaller than OK sample value, enter 255 in Upper Level ﬁ eld and intermediate

value in Lower Level ﬁ eld.

Option[0-16]

Enter 0.

Shift[V1-V8]

Set the OK range. The maximum value is 100 in Upper ﬁ eld and minimum value

is 0 in Lower ﬁ eld.

Memorize to -

Upper, Lower

Set OK range. The maximum value of Upper is 100 and minimum value of Lower is 0.

Sample

Shows the percentage of the speciﬁ ed brightness level in the inspection window.

The graph in the lower

right side of the dialog

The Histogram of Luminance bar graph shows the number of pixels of every

bright level. Green area is the speciﬁ ed area by Upper Level and Lower Level.

The sample Value shows upper limit and lower limit.

1.11.3 Setting Procedure

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

Step2: Adjust the Black/White window position to surround the solder ﬁ llet.

Step3: Enter values in the Upper ﬁ eld and the Lower ﬁ eld.

NOTE

100 is for the Upper ﬁ eld and 60 is for the Lower ﬁ eld as a rough guide.

Step4: Make sure that the sample value is in the OK range. If it is out of the OK range, adjust values

in Upper Level and Lower Level.

CAUTION

Inspection windows are created at either end of the chip component after auto

deployment of chip component.

NOTE

The percentage of the speciﬁ ed brightness level in the inspection window is

displayed as a sample value.

NOTE

Press the black-white button on the right side of Sample (refer to the red circle in

Figure 1-32). The OK area will be colored in gray.

Step5: Enter the appropriate vector into the Shift ﬁ eld by selecting from V1 to V8 according to the

vector used in Memorize to in the Adjust window.

Step6: Press Inspect. Make sure that the inspection is completed properly.
