iPhone and iPad Schematics
Schematics are essential for iPhone and iPad logic board repair. They show the full circuit — every component, every trace, every net — and make troubleshooting far more systematic than guesswork. Apple considers them proprietary, but several sources exist for technicians.
Schematic Sources

Beyond Schematics: ZXW Tools
For most board-level repairs, a schematic alone isn't enough — you also need to know where each component physically lives on the board. That's what ZXW Tools provides: a bitmap and position map that overlays the schematic data directly onto a photograph of the logic board.
