(1) Multi-plane matrix PWB
This is a PWB on which all circuits have the same orientation and the distance (pitch)
between circuits is equal.
Select the reference circuit (select a circuit at the left bottom, in general) among
circuits on a PWB.
Then, set the PWB origin and the circuit origin for placing the reference circuit and
enter the information of the number of circuits and the pitch between circuits.
By these data entries, the system places the specified number of circuits on a board
with based on the placement data of the reference circuit that is created on the
“Placement” data screen with shifting the position of each circuit by the specified
pitch.

1) PWB dimensions
Enter the dimensions of the PWB including all circuits.
2) Reference hole position
* Not used in JX-350.
3) PWB layout offset
In the same manner as a single-plane PWB (“single PWB” as the “PWB
configuration”), enter the position of the PWB layout endpoint viewed from the
PWB origin.
4) PWB configuration
Select the radio button “Matrix circuit.”
When dimension settings are performed for the multi-circuit matrix and then this
matrix is changed into the multi-circuit non-matrix, expansion to the non-matrix
circuit layout is automatically performed.
5) BOC type
For the multi-circuit matrix, it is possible to select "Not use", "PWB mark", or
"Circuit mark."
♦ Do not use: Select this radio button if you do not use a BOC mark at all.
♦ PWB marks/ref. ckt marks are used: Select this radio button if you are to
correct the coordinates of a component placement position with using BOC
marks.
♦ Circuit marks are used: Select this radio button if you are to correct a
component placement position with recognizing BOC marks on each circuit of
a multi-plane (circuit) board. When there are many circuits on a board, this
selection requires much time to recognize marks, but the accuracy of
component placement tends to be higher than that when you select the “PWB
marks/ref. ckt marks are used” radio button.
6) Circuit dimension
Enter the dimensions of a circuit (the dimensions that include all placement
coordinates).
Example)
7) Circuit layout offset
Enter the distance from the circuit origin of the reference circuit to the left
bottom corner (this is an always fixed point regardless of the PWB transport
direction) of the reference circuit.

8) First circuit position
Specify the reference circuit. Enter the position of the origin of the reference
circuit viewed from the PWB origin.
* For a multi-plane matrix PWB, you can specify the PWB origin and the circuit
origin (this can be the PWB origin from which components are placed)
respectively.
To do so, specify the PWB origin with the “PWB layout offset,” and then
specify the circuit origin with the “First circuit position.”
9) Circuit divide No
Enter the numbers of circuits in the X direction (or the PWB transport direction)
and in the Y direction (or the vertical to the PWB transport direction).
The maximum number of circuits varies depending on the contents of the bad
mark coordinate specification in the basic settings.
The system can create up on a multi-plane matrix PWB is as shown below.
Reference bad mark: 1200 circuits
Extended bad mark: 200 circuits
10) Circuit pitch
Enter the distance between the circuits (the distance between the origins of two
circuits, and you have to enter a sign, + or – (minus).) in the X direction (or the
PWB transport direction) and in the Y direction (or the vertical to the PWB
transport direction).
11) BOC mark position, Mark name, Shape
Enter the distance from the PWB origin or the circuit origin to the center of the
BOC mark.
Enter the “Mark name” and “Shape” fields in the same manner as a single-plane
PWB (“Single PWB” as the “PWB configuration”).
- For using 2 points: it is possible to correct the difference between the design
dimensions and the actual dimensions (measured dimensions) and the rotation
direction error. For the third point, leave the field blank. When there are
multiple marks on the PWB, select 2 points on the diagonal lines in all the
placement range.
- For using 3 points: In addition to the case of two points, the perpendicularity
distortion between the X axis and Y axis can be corrected.
JX-350 EPU is not applicable to the teaching.
Enter the X and Y coordinates.
