How is a PCB (Printed Circuit Board) represented in TPC schematics?

A PCB is represented in TPC schematics by a rectangular outline that includes traces indicated on its surface. This will typically show how different components are connected to each other through the pathways or traces that form the electrical connections between them. The rectangular shape is commonly used as it reflects the standard physical form of most printed circuit boards. It conveys essential information regarding the layout, helping designers visualize component placement and connectivity.

The inclusion of traces within this outline is crucial because it highlights the actual routes that electrical signals will travel. This diagrammatic representation serves as a fundamental part of circuit design and analysis, enabling engineers to understand and troubleshoot the circuitry effectively.
