* Try to make a calculation on the supposition of X coordinate = 50, Y coordinate = 35, PWB
dimension X = 300, and PWB dimension Y = 200.
In the case of X = [X] + [0] + [0]X - Board + [0], the X value after transformation is 50.
In the case of X = [X] + [0] + [1]X - Board + [0], the X value after transformation is 350.
In the case of X = [0] + [Y] + [0]X - Board + [0], the X value after transformation is 35.
In the case of X = [X] + [0] + [-1]X - Board + [0], the X value after transformation is -250.
In the case of X = [X] + [0] + [0]X - Board + [10], the X value after transformation is 60.
In the case of Y = [0] + [Y] + [0]Y - Board + [0], the Y value after transformation is 35.
In the case of Y = [0] + [Y] + [1]Y - Board + [0], the Y value after transformation is 235.
<Exercise 2>
* The bottom-side placement coordinates are defined in the coordinate system viewed from
the top side as shown in the following figure, transformation is required.

This point becomes an origin as
viewed from the bottom side.
Consequently, it becomes as shown below.
At this time, the expression is as follows:.
X = [-X] + [0] + [1]X-Board + [-10] = -95+0+150-10 = 45
When converting the placement data, it is defined that numeric data should be converted by
user-defined wizard but no data exists in the file to be actually converted. In this case, 0 is set
as the default value in the field of the output file.

*
When a lengthways-shape component is clamped as a long sideway shape at production, it
is necessary to convert PWB data and placement data. For the placement data, the
placement coordinates and placement angle must be converted. Now, try to convert the
placement data.

The placement data is converted as follows:
X = [0] + [Y] + [0]X-Board+ [0] X=0 + 60 + 0 + 0 = 60
Y = [0] + [-X] + [0]Y-Board+ [100] Y=0 + -70 + 0 + 100 = 30
Theta = ( [T] + [270] ) %360
"100" is the original PWB outer
dimensions in the X direction.
* In the above, "%360" means an arithmetic operation to put the answer within the range of
0 to 359.95 by subtracting 360 from the calculated result when the calculated result in
parentheses exceeds 360º.
In the above calculation for the placement point:
(270 + 270) %360
= (540)%360 = 540 360 = 180
* In addition, it is necessary to make a change according to 0º to 359.95º to be used for the
JUKI production program when there is minus data exists, for example, when the
placement angle is defined as -180º to 180º in the CAD data.
The expression is as follows:
θ = ([θ] + [360]) %360
Regarding the PWB layout offset and PWB outer dimensions, they must be changed.
Changing the PWB layout offset
Refer to "7.3.2. Custom transformation settings (PWB) screen ".
Changing the PWB outer dimensions
When changing the PWB outer dimensions, change it in the data change dialog
box.

7.4 Section definition screen
Define each section data list of PWB, placement, and component defined in the "Global Setup"
screen.

* When multiple PWB sections are set, the "Section Definition" screens corresponding to the
set number are displayed.
