In reality, it's more flexible than imagined, especially suitable for devices with limited space but requiring stability, such as smartwatches or small sensors. In my IoT projects, I found that switching to a 4-layer structure significantly reduced signal interference. Placing the power and ground planes on the inner layers not only freed up space on the outer layers but also improved electromagnetic compatibility. Adjusting the layer stacking based on project requirements is key to truly leveraging the advantages of 4-layer PCBs..."}
