⑰ On the basis of the currently measured values, the minimum and maximum heights are
determined automatically.
- Minimum Height < Height < Maximum Height
- The minimum height is 1/2 the current one and the maximum height is +100um above
the current height.
- If the measured height is below the minimum height or above the maximum height, the
part is treated as a poor quality one.
⑱ Length Slope
- If the long-axis direction deviation between left and right heights is greater than the
length slope, the part is treated as poor quality.
- This is used to detect fine lift.
⑲ Width Slope
- .If the short-axis direction deviation between left and right heights is greater than the
width slope, the part is treated as a poor quality.
- This is used to detect fine lift.
⑳ Rotation Angle(option)
- If the rotational angle of chips is greater than the Rotation Angle, the part is treated as
poor quality.
5.7.8 Inspection Results
21 The inspection results are displayed in „3D Mounting‟ item for the Type.
- The average height corresponding to the regions of 1 Pos, 2 Pos, 3 Pos, and 4 Pos.
Length Slope: The long-axis direction deviation of left and right heights
- Width Slope : The short-axis direction deviation of left and right heights

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.

5.8.2 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..
