Boardview for the Apple iPad Air, stored in the .bvr format at 214 KB. The file name states only the model, with no board number, revision or generation, so check that the component placement agrees with your logic board before relying on it. Boardview data maps every part and net on the PCB, which makes it quick to locate a capacitor on a shorted rail, identify the pins of a charging or display connector and choose safe test points. A viewer program with BVR support is needed to open and search the layout.
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 @SMART_PHONE_SCHEMATICS. Enginerys does not host this file.
