The XDF Viewer is a web browser tool that allows departments to view current design data and associated errors. The results can be reflected onto the ADM system. Results can be transferred back and forth in real time, and on a data to data basis. Division managers can check data and approve the results, while other divisions can review data and ask for advice. Comments can be added onto the design allowing designers to correct the design as directed. PCB Manufacturers can refer to the check results and add modification requests where necessary.
