8. The next step is to verify the polarity indicators

are facing common directions to device polarities on

the PCB. Use Tantalum Capacitors or ICs to verify the polarity indicators are pointing in the same

direction (towards or away from polarity markings) in both (X) horizontal and (Y) vertical directions.

9. Polarity markers and CXF data can be adjusted by using the Layout Viewer > Top Menu Button Bar.

Additional Top Menu functions (not relevant to this task) are described

Layout Viewer > Top Menu

10. Button Bar functions are described in the table below:

Button Icons Function Description

Magnification Increase or decrease magnification of the image displayed in the

Layout Viewer display window.

Fit-to-Screen Scales (increases or decreases) the scanned PCB image to fit

inside the Layout Viewer display window.

Flip X CXF Flips all CXF data (right-to-left or left-to-right) around the X-axis.

Flip Y CXF Flips all CXF data (top-to-bottom or bottom-to-top) around the Y-

axis.

Rotate CXF Rotates all CXF data (CW or CCW) in 90° increments (0°, 90°,

180°, 270°)

Flip Markers Flips only the Y-Axis polarity marks (top-to-bottom or bottom-to-

top).

Rotate

Markers

Rotates all polarity marks (CW) in 90° increments (0°, 90°, 180°,

270°)

IMPORTANT! Before saving changes to the CXF file; verify the polarity indicators are facing

common directions to device polarities on the image of the PCB.

11. Use <

> Button to change (correct) the X axis direction of the XY data in reference to the scanned

image. Press the button repeatedly, while viewing the X axis polarity marks. The marks will rotate (CW)

in 90° increments (0°, 90°, 180°, 270°). Rotate these marks until the X axis and Y axis polarity marks
