<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
The optimizer arranges the feeder of the front feeder base first.
10-9
Optimization
Rear
The optimizer arranges the feeder of the rear feeder base first.
<Twin/Join> combo box
Prioritize the gantry to place parts on a PCB loaded to the conveyor.
Join
Selected when producing the same models at the front and rear in small
quantity. Since it is possible to use the front and rear feeder together, this
mode can be used when performing production by installing a small quantity
of feeders.
Twin
Selected when producing the same models at the front and rear in large
quantity. Since feeders must be installed at the front and rear, many feeders
must be installed.
Join (Partial Twin)
Used when performing mixed production of the same model at the front and
rear in the join mode and twin mode.

As shown in the following figure, in the case of the model for which parts ① ,
② and ③ are placed, if the number of placement points allocated to the part
① is significantly large and the number of placement points allocated to the
parts (② and ③) are small, the front and rear gantry place the part ? in the join
mode, placing the remaining parts (② and ③) in the t
win mode.
1: The part to which the largest number of placement points are allocated
<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.
<Improve Balance(Uncheck=5:5)> check box
Used to adjust the pickup and placement load of the front and rear gantries.
If this check box is selected, the gantry corresponding to the work station at which
a PCB is loaded picks and places more parts than other gantries.
If this check box is not selected, the front and rear gantries perform the same level
of pickup and placement of parts.
