Motherboard boardview for project QD-JW6, labelled MB, in .bdv format at roughly 1.00 MB. The name carries no revision, so compare the silkscreen on the board with the file before trusting component references. Codes of this QD style come from Quanta Computer notebook projects. A boardview viewer such as FlexBV or OpenBoardView lets a technician search a part designator, highlight every pin on a net, find test points and track down shorts on power rails, and works best paired with the matching schematic.
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 @pepeelectronica. Enginerys does not host this file.
