1.11.5 BrightLevel Setting Procedure

Step1: Select the inspection window which the BrightLevel result needs to be applied (Black/

White is taken as an example in this section). Right-click the window, select Copy and

change the Algorithm to BrightLevel.

Step2: Enter an arbitrarily value in Bright and 0 in Dark to specify the percentage of the brighter

area in the inspection window. Enter 0 in Bright and an arbitrarily value in Dark to specify

the percentage of the darker area in the inspection window.

NOTE

Display the brightness level which accounts for the speciﬁ ed percentage of an area

when Black/White is used as a sample value.

NOTE

Select Black/White as Algorithm and press the black-white button in the right side

of Sample. The brightness level in OK range will be colored in gray. Use the image

as a rough guide.

Figure 1-35 OK Range

Step3: 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.

CAUTION

Do not enter any value into the Shift ﬁ eld when using the result of BrightLevel for

misalignment correction.

Step4: Enter M1 into the Memorize to ﬁ eld.

CAUTION

Any value from M1 to M8 is available. Enter it in the appropriate ﬁ eld to reﬂ ect the

result to other algorithms.

Step5: Enter M1 into the appropriate ﬁ eld of an algorithm which requires the BrightLevel result.

NOTE

In case the inspection result of BrightLevel is used for the solder paste inspection of

a chip component, enter M1 in Upper Level or Lower Level depending on the

brightness level.

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

1.11.6 Algorithm LandJudgement

LandJudgement is the algorithm to perform Black/White with two lightings.

Specify the brightness level for each lighting. The algorithm calculates the percentage of the area

where the two brightness levels overlap, and displays the percentage as Sample.

LandJudgement is suitable for solder paste inspections of chip components.

Parameter Description

Lighting

The selected lighting in this ﬁ eld does not inﬂ uence the inspection result.

Select two kinds of lightings to use LandJudgment. Press Set in the right side

of Algorithm. Select two lighting in this dialog. Default setting is TopLight and

SideLight.

Algorithm Select LandJudgement.

[Lighting1]Lower Level,

[Lighting2]Lower Level,

[Lighting2]Upper Level,

[Lighting1]Upper Level

Specify brightness level in each lighting. The percentage of the area where the

speciﬁ ed brightness levels in each two lighting overlap in the window is displayed

as Sample.

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

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

0 in Lower.

Sample

Calculates the percentage of the area where the two brightness levels overlap,

and displays the percentage as Sample.

1.11.7 LandJudgement Setting Procedure

Step1: Select two kinds of lightings to use LandJudgment.

Press Set in the right side of Algorithm and select two lightings in this dialog.

Step2: Specify the brightness level for each lighting.

NOTE

Calculates the percentage of the area where the two brightness levels overlap, and

displays the percentage as Sample.

Step3: Set the OK range. Enter values in Upper and Lower.

Step4: Enter the appropriate vector into the Shift ﬁ eld by selecting V1 to V8 according to the vector

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

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