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.
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.
Rotation Angle (option)
- If the rotational angle of chips is greater than the Rotation Angle, the part is treated as
a poor quality.
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
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

Example for Poor Quality due to Lift
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.

5.7 Odd Parts
The objective is to inspect the lift of odd parts (BGA, Connector, etc.).
5.7.1 Selection of Window for Mounting Inspection
With the window button, select and add the window for mounting inspection.( ).
* In general, a new window is not added and “Use 3D Inspect“ option is checked and used on
the window for mounting inspection which has already been taught.
5.7.2 Selection of “Use 3D Inspect “ Option
Check “Use 3D Inspect” item in the window parameters for mounting inspection.
5.7.3 Projector Selection
Select the projector to be used in the inspection.
- It is possible to select the east, west, south and north projectors, and they are selected
by default values.
- In general, it is recommended that 4 projectors be used.
In case only one projector is used, the measurement may not be made due to noise.
