perform optimization.
<Array Options> group
Used when designate display method and optimization option of the MMI step
program when editing the array PCB.
<Extend> check box
In case of array PCB, <Extend> check box can be ticked. Then, MMI performs
optimization considering one array PCB includes all the array installation
positions. Accordingly, work efficiency is improved.
When the <Extend> check box is not selected, selection of either “By PCB” or
“By Point” is possible.
<By PCB> option button
Creates the step program so that the optimizer performs optimization only for one
small PCB and performs work for several small PCBs in order.
<By Point> option button
Performs work in order on the second placement point of the first array after
finishing the work on the first placement point of the array, the first placement
point of the second array, and the first placement point of the last array.
Generally, when many nozzles are replaced, it is efficient to perform work in the
manner applying ‘By Point’.
However, work efficiency may be lowered if there are many defective unit PCB’s.
<Options> group
Sets the selection condition for the optimizing algorithm executed by the optimizer.
<Search Depth> combo box
Select the level at which the placement sequence is optimized.
Quick
Optimizes the placement sequence based on the nearest placement point. In
this method, the time required for the optimization is relatively short.
Deep
The optimizer compares all possible placement cases for all placement points
to determine the optimum placement sequence. In this method, the time
required for the optimization is relatively long.
<FDR Base Priority> combo box
Enables to give priority while the optimizer arranges feeder.
Auto
The optimizer arranges the feeder automatically.
Front

LED placement
The optimizer arranges the feeder of the front feeder base first.
Rear
The optimizer arranges the feeder of the rear feeder base first.
<Tape-Tray Mixed Cycle> check box
Allows part placement to be performed for the parts to be fed to the tape feeder
while replacing the part in the tray feeder.
<Pallet Sequence> check box
Optimizes the tray pallet pick-up sequence when executing the optimizer.
<First Placing Group: Height<= > check box
Used for installing the parts with lower height than the height input in the right
side edit box. Upon selection of this check box, the edit box is activated. Input the
height of the part here.
<Last Placing Group: Height>= > check box
Used for installing the parts with upper height than the height input in the right
side edit box. Upon selection of this check box, the edit box is activated. Input the
height of the part here.
<Time(sec)> edit box group
This group inputs the time for executing each movement in the equipment. It is used to
calculate the working time at the optimizer. In addition, the values of the tray Y and
tray Z may have influence on the determination of the work sequence.
Therefore, in order to increase the work efficiency and to get the exact estimate of the
working time, the value as close as possible to the actual value shall be inputted.
Conveyor: Time (second) taken until the PCB is fixed by the backup table since
being transferred to the workstation.
Tray Z: Time required for the multi-tray feeder to move in the Z direction (sec)
Tray Z: Time required for the multi-tray feeder to move in the Z direction (sec)
Shuttle : Time required for the pad of the shuttle tray to complete one cycle (sec)
