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, enter the position of the PWB layout
endpoint viewed from the PWB origin.
4) PWB configuration:
Select the “Non-matrix circuit” radio button.
5) BOC type:
Select the radio button in the same manner as when you select the “Matrix circuit”
in the “PWB configuration” column.
♦ 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 dimensions:
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.
8) First circuit position, Circuit divide No., Circuit pitch:
You do not have to set these fields when you select the “Non-matrix circuit” radio
button in the “PWB configuration” (they are not available).
When you select the “Matrix circuit” radio button, enter a value in each field.

9) BOC mark position, Mark name, Shape:
Enter the distance from the PWB origin or the circuit origin to the center of a BOC
mark.
Enter the “Mark name” and “Shape” fields in the same manner as a single-plane
PWB (“Single PWB” as the “PWB configuration”).
♦ Using 2 points: It is possible to correct the difference between the design dimensions
and the actual dimensions (measured dimensions) and the rotation direction error.
For the third point, leave the field blank.
When there are multiple marks on the PWB, select 2 points on the diagonal lines in
all the placement range.
♦ For using 3 points: In addition to the case of two points, the perpendicularity distortion
between the X axis and Y axis can be corrected.
When “PWB marks are used” is selected as “BOC type” on the “Basic
setting” screen, this is the distance from the PWB origin to a BOC mark.
When “Circuit marks are used” is selected, this is the distance from the
circuit origin to a BOC mark.
For using a long PWB:
For a large-shaped PWB whose external length X exceeds 650mm, set
the first and second BOC marks; for an optional large-shaped PWB whose
external length X exceeds 1200mm, set the first, second and third BOC
marks.
However, if the circuit is divided in the X direction and circuit BOC exists,
an error may be displayed at the start of production, disabling production.
JX-350 EPU is not applicable to the teaching.
Enter the X and Y coordinates.

10) Bad mark position:
It is selected whether the bad mark is used or not. When you select “No-use”,
“***” is displayed. When you select “Use”, enter the length from the circuit origin
(circuit position reference) to the bad mark center position.
* In the above case, enter X = a and Y = b.
<Usage of a bad mark and the operation flow>
i) Enter coordinates of a bad mark into PWB data (that is, to the “Bad mark
position” fields.)
ii) At machine setup, adjust the bad mark reader.
iii) Before feeding a PWB, affix a bad mark at the spot specified with the bad
mark coordinates on a defective circuit.
iv) Before the start of production, the OCC or bad mark sensor reads a bad mark of
each circuit. When a bad mark is recognized, components are not placed on the
corresponding circuit.
The requirements for a bad mark: the mark must be distinct in the color
from a PWB, and its diameter must be 2.5 mm or greater. If a bad mark
is used, the production time will be longer by the mark recognition time.
* For the extended bad mark, see "4.1.2.5 "Ex. bad mark" screen."
* If the bad mark is set out of the circuit, use an extension bad mark.
11) PWB height, PWB thickness, and Back height:
Enter these fields in the same manner as those for a single-plane PWB.
a
b
Circuit origin (circuit position reference)
Coordinates of a bad mark
