4.2.1.3 Setting the optimization conditions
The optimization result may vary depending on the settings on the “Component supply
count” dialog box described above and those on the “Optimization” dialog box described
below. Set the optimization conditions of a production program only after understanding
the descriptions below well.
When you click the [Optimization]/[Optimization] commands from the menu bar, the
“Assignments” screen appears.
Set the six categories of conditions including the “Assignments” option.
Click this tag to change the screen for the corresponding option.
Option Description
Assignments Specifies the option to be checked with the Optimization utility when it assigns a
nozzle or Pick data.
Area Specifies the area to which a feeder can be assigned.
Place order Specifies the option to be used for changing the component placement order.
Model option Specifies the option unique to the model.
Feeder option Specify the options related to the feeder layout.
Non-stop option JX-350 is not applicable to the non-stop option.
This button registers new settings as the initial
values. The new settings will be displayed in the
beginning when the system is booted the next time.
This button invalidates your registered
settings and restores the standard
settings (initial values of the machine).
This buttons executes the
optimization function.
This button stores your settings, and
closes this screen.

(1) “Assignments” option
Set "Nozzle layout" and "Feeder layout" intended for dividing (optimizing) the program
data.
1) Nozzle
Select which nozzle layout you want to use, the nozzle layout set on the “EPU
setup” menu or the optimized nozzle layout.
a) Use machine setup nozzle:
The nozzle settings on the “EPU setup” menu will be used as they are. The
current nozzle layout can be used as it is. This option does not need any
changeover time, and thus select this option for flexible manufacturing.
b) Auto arrange empty nozzle positions:
The permanent nozzles set on the “EPU setup” menu are used as they are,
and the nozzles required as the result of optimization are assigned to the
empty area of the ATC. If your system has enough nozzles to do this
operation, select this option. Note that you have to change the settings on
the “EPU setup” menu to set the additionally assigned nozzles if you select this
option.
c) Auto arrange nozzle.
The nozzle layout is optimized with ignoring the settings of the nozzles made
on the “EPU setup” screen.
In this case, the production tact becomes speedier but nozzle re-layout and
EPU setup setting changes are required. Accordingly, preparation may take
more time.

2) Pick Data
Specify whether to assign feeders according to a feeder layout specified in the
“Side” field on the “Pick” data screen or optimize the feeder layout with ignoring
this layout.
a) Use manual position assignment:
Perform the specified feeder layout as specified and optimize only the feeder
layout set to "Auto selection."
b) Auto assign all data:
Ignore the specified feeder layout and optimize the whole feeder layout.
Once you execute the optimization function, its result will be reflected in the “Side” field of
the “Pick” data screen also. To retry optimization from the beginning after data editing is
finished after this, select "Distribute all." To perform additional layout for only changed
portions, select "Distribute items in the "Auto selection" status."
3) Put stick components together in the same feeder.
For using multiple old stick feeders (which feeds multiple sticks to one stick
feeder), put the stick components of the same type together into a single stick
feeder.
If you remove the check mark, the stick components of the same type are
arranged so that they may be picked up simultaneously.
4) The lane assignment of the tape feeder is fixed
When you use an 8-mm electric double tape feeder, the system changes only the
feeder assignment while maintaining the lanes already assigned. Actual
assignment varies depending on the setting of the “Pick Data” options.
Example: when one lane of an electric double tape feeder (ETF8D)
is already assigned and a component has to be assigned
additionally to an 8-mm tape feeder
“Pick Data” option
Setting of the “The
lane assignment of
the tape feeder is
fixed” check box
Result of optimization
“Use manual
production
assignment”
Checked
Any additional component for an 8-mm feeder will not be
assigned to an unoccupied lane of an ETF8D whose one
lane has been already occupied.
Not checked
An additional component for an 8-mm feeder will be
assigned to an unoccupied lane of an ETF8D whose one
lane has been already occupied.
“Auto assign all data”
Checked
Any additional component for an 8-mm feeder will not be
assigned to an unoccupied lane of an ETF8D whose one
lane has been already occupied.
An additional component for an 8-mm feeder will be
assigned to another ETF8D.
Or such a component will be assigned to another position
while the current lane assignment of the ETF8D whose one
lane has been occupied is maintained.
Not checked
The system clears the current assignment, and reassigns all
feeders and lanes.
