5. There are several tabs at the bottom of the [Machine Configuration] pane. Select the
[Process Options] tab and the process options for the machine display.
6. Enter the appropriate panel stopping position correction settings process settings for the
machine if the panel stopping position correction function is turned on. Refer to the table
below for information on these settings.
Setting Description
Scan Area X/Y This specifies the size of the area in the X- and Y-direction
checked for the panel edge when correcting the panel
stopping position.
Shutter Speed This setting specifies the shutter speed used by the mark
camera when checking for the panel edge. The larger the
value, the slower the shutter speed and the image
becomes brighter. Generally, the default setting is
appropriate.
Color Specify which lighting should be used to check for the
panel edge. Different settings will be required depending
on the color of the panel. Generally, the default setting is
appropriate.
Pattern Specify which lights should be used to check for the panel
edge. Different settings will be required depending on the
color of the panel. Generally, the default setting is
appropriate.

3.4.3 Package-on-Package placement (from NXT V4.10)
The package-on-package (PoP) placement function uses pressure control to stack parts on
top of parts that have already been placed.
Note: The distance used for the placing pressure control start height (H) varies depending on
whether the lower and upper parts are stacked at the same module or at different modules.
* If parts are stacked at the same module, H is equal to the top of the lower part that has
already been placed plus 2.5 mm.
* If parts are stacked at different modules, H is equal to the premounted parts height
specified for the module at which the lower part is placed.
Restrictions:
If PoP placement is performed at paired modules, the lower part and upper part of the stack
must be placed at the same module within the pair (see the figure on the lower left).
However, the lower part can be placed at a module within a set of paired modules, and then
the upper part can be placed at a different module within a different set of paired modules
(see the figure on the lower right).
(1) The nozzle (Z-axis) is lowered at the specified speed from the placing
pressure control start height (H).
(2) The nozzle places the part, pushing down with the specified pressure.
(3) The head pauses for the specified time.
(4) The nozzle (Z-axis) rises to the placing pressure control end height (same
as H) at the specified speed. After reaching the placing pressure control
end height, the nozzle continues to rise at normal speed.

Job settings
When performing PoP placement, in addition to normal settings, it is also necessary to
specify settings for Coordinate data and Shape data.
Note: Fuji Flexa V2.5.1 or higher is required to perform PoP placement.
Specifying placment data settings
1. Select the [Top] or [Bottom] tab from the job information bar depending on the side of
the panel for the part.
2. Double-click [Coordinate] to display the “All” window.
3. There are several tabs at the bottom of the [Coordinate] pane. Select the [Placement]
tab and the placement sequences are displayed.
4. Locate the placement sequence for the part to be placed on the other part.
5. Click in the blank data cell for [Stack Target] and enter the value from the [Ref] column
(the reference designator) for the part on the bottom of the stack (refer to the picture
above).
6. Repeat these procedures for all parts that are to be stacked.
