Displayed menu items
Mark ID: Enter a mark ID. You can enter up to eight half-characters.
When you omit it, the system automatically assigns an ID to the
mark.
Linked pla: Displays the number of placement data records that refer to the area
bad marks when you open the Area Bad Markscreen. You cannot
edit this item.
X: Enter the X dimension from the position regulated in the Reference
field to the center of the area mad mark.
Y: Enter the Y dimension from the position regulated in the Reference
field to the center of the area mad mark.
Reference: Select the reference position of the coordinate system, the origin of
the circuit (circuit reference position) or that of the board (board
reference position).
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.
Note: For a single-circuit PWB, the circuit reference can be selected. In this case,
set the coordinates from the home position of the PWB. The coordinate values for X
and Y can be obtained by teaching.
Each of the above items cannot be edited when the screen is opened by "View."
When the screen is opened by "View", they are displayed in the line selection mode.
Operation buttons
OK: Saves the edited data and returns to thePlacementdata list screen.
At that time, the use of mark group is not set.
Cancel: Discards your editing and returns to the “Placement” data list screen.
When you double-click or press the Placement list tab to quit this Area Bad Mark
screen, the system redisplays thePlacementdata list screen without setting any link
to the Placement data.
The color of a bad mark should be able to be distinguished from that of a board, and
its diameter should be 2.5 mm or more. Note that when you use a bad mark, the
cycle time becomes longer by the mark recognition time.
(9) Skip
When you select Yesfor this field, the system skips component placement on the
corresponding position: that is, the system does not place any component on the
position specified on this line. This function is mainly used for checking.
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.

(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 componentsoccurs 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 Placementdata
screen. If you do not find any problem on this screen, check each entry on the
PWBdata screen. (Check the settings of PWB layout offset,First circuit
position,” “Circuit layout offsetand each coordinate entered on theCircuit
layoutscreen especially.)
