The author shares their experience of shifting from blindly following calculation formulas to focusing on practical layout, solving signal interference by adjusting component placement, and even achieving better performance by placing RF modules adjacent to digital layers. The article emphasizes the need for intuition and flexibility in design, opposes the rigid application of standards, highlights the importance of reserving routing space, and argues that PCB design is more like an art form requiring negative space."}
