 When defining the multi-circuit non-matrix, the circuit layout field (X, Y, and angle of multi-

circuit non-matrix circuit position) and other fields cannot be defined in the same PWB

section.

For details, refer to the last part of Appendix A.

When PWB data exists in multiple positions, set the number of PWB sections to 2 so that the

PWB data can be defined by dividing it into two parts. In the following example, the PWB ID is

defined in the first place and the PWB outer dimensions, PWB layout offset, and BOC mark

position are defined in the second place.

Flexline CAD Tutorial PWB ⇐ PWB ID

TR1, 85, 65, 0, sot23 ⇐ Placement data

TR2, 100, 50, 90, sot23 ⇐ Placement data

165, 125, 165, 0, 5, 10, 160, 120 ⇐ PWB outer dimensions, PWB layout

offset, BOC mark position

Note: The data that cannot be defined once cannot be converted by Flexline CAD.

7.2.3 PWB unit and placement unit

When the number of sections of "PWB" or "placement" is set to 1 or more in "Section", "PWB

scale/unit" or "Placement scale/unit" can be used. The scale and unit related to dimension and

rotation can be set.

The dimension unit can be selected out of "mm", "1/100 mm", "cm", "inches", and "mils". The

rotation unit can be selected out of "degrees" and "radians."

The unit is selected by default, which was set in “Change” – “Unit of default” in the environment

setup.

Figure 7.2.3-1 Unit

The unit converting method is as follows:

Dimension

1 inch = 2.540 (x) 1/100 mm = 25.4 mm = 2.54 cm = 1000 mils

1 mils = 2.54 (x) 1/100 mm = 1/1000 inch = 0.0254 mm = 0.00254 cm

Rotation

2 π rad (radian) = 360º (degree) (π = 3.141592654 ...)

1º (degree) = (π ÷ 180) rad (radian)

7.3 Coordinate transformation

In CAD data, the position and direction of the component to be placed on the PWB are

described. For this purpose, various coordinate systems are adopted. In the case of some CAD

data types, the unit of dimension is different. To process a new format, Flexline CAD converts

the numeric data of the data file into an amount measured on the JUKI standard direction and

standard system.

* In coordinate transformation of the "Global Setup" screen, select the transformation type.

7.3.1 Standard Transformation Settings screen

In coordinate transformation of the "Global Setup" screen, specify "Standard transformation"

and click the [Next] button. Then, the following screen is displayed. Click one image of "0º",

"90º", "180º", and "270º" and set Coordinate transformation.

Figure 7.3.1-1 Standard Transformation Settings

* The rotation angle specified here is used for conversion of PWB data and placement data

of both top side and bottom side.

7.3.2 Custom transformation settings (PWB) screen

In coordinate transformation of the "Global Setup" screen, specify "Custom transformation"

and click the [Next] button. Then, the following screen is displayed.

Figure 7.3.2-1 Custom Transformation Settings (PWB)

* Click the "Restore Default Values" button to set the default values for all the values displayed

on the screen.

 Reference hole position

An expression to convert the reference hole position data into the standard transformation

system is defined.

Figure 7.3.2-2 Reference hole position

 PWB layout offset

An expression to convert the PWB layout offset data into the standard coordinate system is

defined.

From the pull-down menu, select this item and set each

of the top side and bottom side.
