4.1.2.2.3 Dimension settings (multi-circuit PWB)

When a PWB in which multiple same circuits are arranged on a single PWB is called

“multi-circuit PWB.” As placement data, create the data for a single circuit (this circuit is

called “reference circuit”) and enter the circuit arrangement information (inter-circuit pitch,

number of circuits, etc.) into the PWB data.

Two types of multi-plane PWBs are available: matrix circuit board and non-matrix circuit

(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.
