(10) Trial
Set the test run to "Yes" or "No." When the specified placement point is specified in
the test run range of the production condition screen, a test run is executed for only
the placement data which is specified to "Yes" in this item.
As the initial value, "No" is set.
To make a change, press the Edit key or right-button of the mouse and select data
from the list.
If data is selected from the pop-up menu when the cursor is at "Skip" and multiple
lines are selected, the same value is set for the all the selected records.
(11) Layer
This function allows you to specify the order of component placement.
The lower numbers will be given the higher priority (i.e., to be placed earlier). As the
initial value, "4" is set.
When optimization is executed, the order of placement will be automatically defined
regardless of the data input order. (When “No components” occurs at production, it is
impossible to proceed to the production of the next layer unless the production of a
younger No. layer is completed.) Then, the system refers to the layers to determine
the optimized component placement order on the same layer.
To make a change, press the Edit key or right-button of the mouse and select data
from the list.
If selection is performed from the pop-up menu when the cursor is at "Reference" and
multiple lines are selected, the same value is set for all the selected records.
Example) If the system places QFP components and a chip component as shown in the
figure below, it has to place a chip component first.
In this example, when you specify the layer 4 for a chip component, and the
layer 5 for a QFP, the system places a chip component whose layer number is
smaller first, and then a QFP.
<Placing QFP on the chip.>
・Layers are also used for adjacent placement/laminated placement.
<A component is placed near a tall one.>
<IC components are stacked.>

Area check
The system checks that a component placement position is within a PWB (for a
single-plane PWB) or within a circuit (for a multi-plane PWB) at the following
timing:
1) At data entry
The system checks the component placement area when you enter or change
the placement coordinate X or Y.
If an error occurs, the system displays the following warning message.
• <OK>: The system validates data you entered, and displays an asterisk
mark (*) left to the placement data number indicating the range over
error (see the figure below). When you enter a value within the
range, this mark disappears.
• <Cancel>: The data you entered becomes invalid, and the system allows you
to enter data again.
2) When you switch the displayed data screen
When you switch the displayed data screen (for example, by selecting
component data), the system checks the component placement area.
If an error occurs, the system displays the following warning message.
• <OK>: The system resume switching the displayed data screen.
• <Cancel>: The system stops switching the displayed data screen.
* If the area check error occurs, check the data entered on the “Placement” data
screen. If you do not find any problem on this screen, check each entry on the
“PWB” data screen. (Check the settings of “PWB layout offset,” “First circuit
position,” “Circuit layout offset” and each coordinate entered on the “Circuit
layout” screen especially.)

4.1.4 Component data
On the "Component" data screen, enter the detailed information on the "Component
name" that was entered on the "Placement" data screen.
Therefore, data will be created for the number of component names entered on the
"Placement" data screen.
4.1.4.1 Viewing the component data screen
Two types of component data screens are provided: “List” screen and “Form” screen.
On the “List” screen, the system displays a list of the summary information of two or more
components.
You cannot enter any data on this screen, but you can check how you have completed
component data.
The component name items without data setting are not set are indicated in yellow.
In the component list screen, all the items are handled as sort keys and their data can be
displayed in a sorted way.
When the component names set in the component data are not used by placement data,
the items are displayed in pink.
When Component skip is set, the items are displayed in orange. For Component skip,
see "Component skip" of "4.1.4.2.5 Place condition."
