What is a ground plane and why is it important for high-speed signals?
Struggling with intermittent signal integrity issues or failing EMC tests? You might be overlooking the most critical part of your PCB layout: the return path. Many engineers focus only on the signal trace, forgetting that current travels in a loop, leading to costly redesigns and project delays. The solution is to understand that a solid ground plane is the essential, low-impedance highway for your signal’s return current.
