Aligning CXF (XY) data to the PCB image is accomplished to properly scale and align the XY overlay data with
respect to the scanned PCB image. This is accomplished by identifying the location of (3) three components
(automatically selected from the CXF file by the system: Lower-left, lower-right and upper-left).
There are (3) three methods of identifying the devices used perform CXF to PCB alignment:
Using REF IDs screened onto the PCB (if available). See: CXF to PCB Alignment Using Screened REF
IDs
Using the Layout Viewer tool. See: CXF to PCB Alignment Using the Layout Viewer
Using an Assembly Drawing to manually locate the parts (Practical for PCBs with few devices).
