Apple boardview file for logic board 820-3330, revision B, supplied as a ZIP of roughly 235 KB. The 820-prefixed number is Apple own board numbering, found on the PCB silkscreen. With a viewer such as OpenBoardView or FlexBV, a technician can locate components, inspect which pins share a net, and find test points while diagnosing missing rails or shorts. Before relying on the layout, check that the board number and revision on your logic board match 820-3330-B exactly.
