⑤ Use Ref Manual (Setting of Reference Surface)
- Set manually the region for planar information.
It is possible to set the height and size together or separately using the check box.
⑥ Detailed Setting
- Set the detailed position for measurement regions of the reference surface and height.
- It is possible to designate the position with a mouse by using „Click Pos‟ button.
5.6.6 Part Information Measurement
Click „Get Info (Measurement)‟ to measure information on the width, depth and height of parts.
* Click „Get Info‟ to display 3D Model, and confirm through the model if the information is normally
measured. (In case it is not measured normally, it is impossible to identify the form of 3D
Model.).
5.6.7 Criteria Setting
MV-9 User Manual
5-252
⑦ 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.
⑧ Length Slope
- If the deviation between left and right heights is greater than the length slope, the part is
treated as a poor quality.
- This is used to detect fine lift.
⑨ Rotation Angle (option)
- If the rotational angle of chips is greater than the Rotation Angle, the part is treated as
a poor quality.
⑩ Use Double Chip Insp
- In case of Chip Type, inspect Double Chip.
In case the height is above the designated one, the judgment is based on Double Chip
5.6.8 Inspection Results
⑪ The inspection results are displayed for the items of 3D Chip Mounting for the Type.
- 1 Pos: The average height of the electrode at 1 Pos area.
- 2 Pos: The average height of the electrode at 2 Pos area.
- Length Slope: Display the deviation between left and right heights

5.6.9 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.
