Apple iPhone 6S boardview saved as a 316 KB .bvr file, covering the logic board component placement. The name states only the model, with no board number or revision. In a compatible viewer you can search parts, highlight a net to see every connected pad and locate test points, which speeds up hunting shorts on main rails, checking charging and audio circuits or replacing damaged passives. The 6S and 6S Plus boards differ, so verify the phone model and board markings before using this layout as a reference.
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 @GENERAL_SMART_PHONE_SCHEMATICS. Enginerys does not host this file.
