iPhone 6 repair pack that pairs schematic 051-9903 with logic board 820-3486, in a 4.11 MB RAR that contains a PDF. Apple numbers its boards 820-xxxx and its schematics 051-xxxx, so these codes identify the exact design. Technicians use such material to trace power rails, find faulty lines on charging, baseband or backlight circuits, and locate test points. Check that the board number printed on the logic board is 820-3486 before trusting component positions or net names.
