Part III Inspection Algorithm

1.15 AreaColor

1.15.1 Inspection Overview

AreaColor is the algorithm to inspect the percentage of speciﬁ ed color in the inspection window.

Extract the component color from two places in consideration of color variability.

Specify any color as OK color. If the percentage of the speciﬁ ed color exceeds a certain value, the

result will be OK. Specify any color as NG color. If the percentage of the speciﬁ ed color falls below a

certain value, the result will be OK.

AreaColor is suitable for copper inspection or missing inspection of chip components.

1.15.2 Parameter Setting

Figure 1-74 AreaColor

Parameter Description

Lighting Select SideLight.

Algorithm Select AreaColor.

Red, Green, Blue[0-255]

A value is automatically entered when component color is extracted.

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.

CHA-Width[0-255]

Default is 30. Enter the bigger value to enlarge the color OK range.

Memorize to -

Upper, Lower

If the speciﬁ ed color is registered as OK color, enter 100 in Upper and arbitrarily

value in Lower. If the speciﬁ ed color is registered as NG color, enter arbitrarily

value in Upper and 0 in Lower.

Sample Shows the percentage of speciﬁ ed color in the inspection window.

1.15.3 Setting Procedure

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

Step2: Extract colors from two places.

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

Extract colors two places to put ﬂ exibility into OK range. One should be extracted

from dark color and another should be extracted from light color.

Step3: If the speciﬁ ed color is registered as OK color, enter 100 in Upper and arbitrarily value in Lower.

If the speciﬁ ed color is registered as NG color, enter arbitrarily value in Upper and 0 in Lower.

Step4: 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.

Step5: Press Inspect. Make sure that the inspection is completed properly.
