4.3.3.2 Dimension setup

A production program represents a position of a component or that of a mark on a board as

coordinates.

The origin of this “coordinates system on a board” is called as the “board reference position”.

・ The board reference position can be set at a desired position on or outside a board.

・ If you use CAD data to create Placement data, use the origin of the CAD data.

The relative position of the “board reference position” to the board positioning mechanism is to be

adjusted with the “board layout offset.”

On the “Dimension setup” screen, settings you have to make vary depending on selection of the

menu item “PWB configuration” (“Single PWB,” “Matrix circuit” or “Non-matrix circuit”).

Furthermore, the items displayed on the screen also vary depending on the positioning method,

usage setting of bad mark, and that of BOC.

(1) Reference

The layout end point of a board is defined according to the board transport direction as shown in

the figure below.

1) Transport direction: left to right

2) Transport direction: right to left

(2) Single circuit PWB

Single-circuit PWB means a PWB on which only one circuit exists.

1) PWB dimensions

Enter the dimensions of a PWB here.

If the machine is supplied with a

dummy PWB, enter the dimensions

of this PWB also.

The same direction as the transport

direction is X and the direction

perpendicular to the transport direction is Y.

2) PWB layout offset

Enter the length from the PWB

position reference to the end point

of the PWB layout.

Enter the distance from the PWB

origin defined by the CDA or other

tool to the reference position (PWB

layout endpoint) if the specified

origin (the CAD origin or an origin

that is unique to a user) must be

used as the PWB origin, for

example, in a case in which CAD

data is used.

When transport is performed by front reference and the PWB flow direction is left to right,

the PWB layout end point is “reference position.” When the PWB reference position is at

the left lower corner of the PWB, enter the (Xb, 0) value in each of the X and Y coordinates

of the PWB layout offset. The Xb is a positive value.

3) PWB configuration

For this item, select [Single circuit].

After the multi-circuit matrix or multi-circuit non-matrix is changed into the single circuit

matrix, single circuit expansion is performed.

At this time, a confirmation message is displayed.

4) BOC type

“BOC” is abbreviation of Board Offset Correction, and is a mark for correcting a component

placement position that helps the system to place a component on a board more accurately.

(It is called a “fiducial mark” also.)

◆ Not Used: Select this button when any BOC mark is not used.

◆ PWB marks: Select this button to use BOC marks on a board to correct the component

placement coordinates.

◆ Circuit marks: This button cannot be selected for a single-circuit PWB.

5) Circuit dimensions

6) Circuit layout offset

7) First circuit position

8) Circuit divide No.

9) Circuit pitch

You do not have to set these items for a single-circuit PWB (these items are disabled).

You have to set them for a multi-plane PWB (“Matrix circuit” or “Non-matrix circuit”).
