Schematic in PDF form for the Apple iPhone 4, a compact 876 KB document. Logic board schematics like this one let a technician follow power rails from the battery connector and PMU, trace signals between the application processor, baseband and peripherals, and identify the components around a suspected short or open line. Any PDF reader opens it, and text search helps locate net names quickly. Pair it with a boardview or placement drawing to find parts physically, and confirm the board revision before trusting individual values.
