For a phone like the Nokia 1280, a schematic diagram is the comprehensive "roadmap" of its internal electrical system. It uses standardized symbols to represent every electronic component—resistors, capacitors, transistors, integrated circuits (ICs), and connectors—and maps out the complex network of electrical pathways (called "traces") on the phone's main printed circuit board (PCB).
