2) Calculating method for placement peak point
Specify the calculating method for the starting point of feeder layout.
a) Arrange a feeder in the mid-point of placement points
Arrange a feeder in a position close to the placement point that is a mid-point
counted from the smallest coordinate value when each placement point is
arranged in the order starting from the smallest coordinate value.
b) Arrange a feeder in the mean point of placement points.
Arrange a feeder in the position closest to the mean coordinate value of all the
placement points.
c) Arrange a feeder in the center point of the PWB.
Arrange a feeder in the position corresponding to the center coordinates of the
PWB.
• When there are many components and placement points are made uniform
over the PWB, both cases leads to the same result.
• Generally, when a part of placement points is separated among all the
placement points, "Mid-point" is advantageous. Otherwise, "Mean point" tends
to be advantageous.
(6) Non-stop option
* JX-350 is not applicable to the non-stop option.
The 2nd closest placement point
(Mid-point in this case)
The 3rd closest placement point
The first closest placement point
Feeder layout when "Feeder
layout in the mid-point" is
selected. (Layout on the base
of the mid-point)
Feeder layout when "Feeder layout in
the mean point" is selected
(Located on the basis of the mean
coordinates among placement points)

4.2.2 Executing the Optimization function
When you click the <Run> button on the “Optimization” conditions setting screen, the
system starts the optimization process.
The following screen is displayed while optimization is executed.
When the system finishes the Optimization function normally, the “Optimization” screen
disappears.
If an error occurs during optimization, the corresponding error message appears on the
screen.
When you click the <Stop> or <Skip> button during optimization, you can stop the
optimization.
The following confirmation message appears on the screen.

4.2.2.1 Checking the divided component placement data
This section describes how to display the placement data divided with the Optimization
function.
Select the [Optimization] command from the menu bar, and then the [Divided [Placement
Data] command from the “Optimization” menu.
• You cannot select this command if you have not performed the Optimization function
(that is, there is no divided placement data file), or if you edit a production program
after executing the Optimization function.
The window like the one shown below appears on the screen.
• A bold line on the “Divided Placement Data” screen in the optimized order indicates a
delimiter of data paired during one component pick-up and placement cycle.
