Boardview in BDV format for the Lenovo ThinkPad board 19770-1, a Wistron-pattern number, packed as a 154 KB ZIP archive. BDV files open in OpenBoardView, FlexBV and similar viewers, showing component placement, part numbers, nets and test points on both sides of the PCB. Used together with the schematic for the same board, it helps locate the physical parts on a failing rail and check for shorts. Match the board number printed on your PCB before trusting component locations.
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 @cynetitsolution. Enginerys does not host this file.
