PCB design involves two critical stages: component layout and circuit connection wiring. The layout is the arrangement of circuit components within the PCB’s wiring area. A well-thought-out layout directly affects the ease of subsequent wiring and significantly impacts the PCB’s overall performance. In addition to meeting circuit functionality and performance requirements, a good layout considers manufacturability, inspection, and maintenance. Components should be placed evenly, neatly, and compactly, ensuring that leads and connections are short, minimizing interference and signal transmission delays.
