[Deletion Character]

When any unnecessary character is attached to the numeric value of "X", "Y", or "Angle" of

placement data, this character can be deleted by specifying it.

For example, when the value of X coordinates is "X1234", [X] will be ignored at conversion

if "X" is entered in advance.

However, note that the deletion character must be the first or last character of the character

string. ("X1234" and "1234X" can be recognized but "1X234" cannot be recognized.)

Enter the deletion character by putting it in """ like ""XY"".

For example, when "X", "Y", and "A" are deletion characters, enter ""XYA"" (including the

double quotation mark). Flexline CAD deletes a blank regardless of whether the deletion

character is specified or not.

* The deletion character is valid for the "X", "Y", and "Angle" fields of placement data.

•

[Default Side]

When no PWB surface is specified in the placement record, the default side is used. For

the default side, select "top side" or "bottom side."

•

[Max. Characters/line]

Set the maximum number of characters per line in the input format. Select one of "2048",

"3072", and "4096."

•

[Permit double-byte character for delimiter]

Check off this item when a double-byte character is included in the delimiter in the field

definition of the input format. When this item is not checked off, only a single-byte character

is used as the delimiter.

7.2.2 Section

In this field, set the target data for conversion out of PWB data, placement data, and component

data. Enter the number of sections (number of data group to be defined) of each data. The

settable number of sections is 0 to 30 for PWB data, and 0 to 1 for placement data and

component data. Accordingly, only one section can be defined for placement data and

component data.

If a larger number of sections than 1 is specified for PWB data, the PWB section definition

screen of the set number is displayed.

•

For multi-circuit matrix or multi-circuit non-matrix conversion, it is necessary to define the

PWB configuration field. (If this field is not defined, single-circuit matrix conversion is

performed.)

•

For defining the BOC mark position, the BOC type field must be defined. For defining the

bad mark position, the mark type must be defined.

 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.
