5.7.9 Reliability Threshold

The height data with low reliability are treated as invalid values in order to remove the

shadow.

- In case the data reliability is lower than the set threshold, the data are treated as

invalid values.

- In case of black-series parts, it may seem that the measurement is not made since

most of them are treated as invalid ones due to the low reliability.

- In case the 3D model of black-series parts does not show the normal form, try again

by lowering the threshold value.

- If the threshold value gets too low, the shadow may not be removed and noise may

be expressed.

5.8 IC Lead

The objective is to inspect the lift of IC Leads.

5.8.2 Lead Direction

Set the direction of leads.

5.8.3 Setting of Parameters for Lead Seq. and Bridge Insp.

Since the information separated from 2D Lead is used in the lift inspection of 3D Lead, first

set the parameters for Lead Sep. and Bridge Insp.

After completing the parameter setting, confirm through the trial inspection if the lead

separation is accomplished well.

* In case poor quality is found during Lead Sep. or Bridge Insp., do not conduct the lift

inspection of 3D Lead..

5.8.4 Setting of Lead-tip Offset and Lead Offset

If “Use 3D Inspection” is pressed, “Lead Tip Tab” is activated.

Set the parameters for Lead-tip offset and Lead offset.

Example)

5.8.5 Use Color Map

- At the end of the Lead Tip Tab, there is “Use 3D Mask Image” check box as shown

below:.

- If “3D Mask Image” is pressed, “Set Color Map” button is activated, If this button is

clicked, the window set for Color Map appears as shown below:

- By using the window set for Color Map, the lead region valid on 2D Image may be

separated and used in 3D inspection.
