Boardview material for Samsung equipment, packed as a 694 KB RAR archive whose name only says Samsung CAD, so no model or board number is stated. CAD-derived boardview files show component placement, part references, net names and pin connections, letting a technician locate test points, follow a rail or find which parts share a shorted net. Extract it and open the files in a boardview viewer such as OpenBoardView or a commercial equivalent, then confirm the board number printed on the PCB matches the data before relying on it.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @generalproblemsolved. Enginerys does not host this file.
