PCB EMI 문제 해결: 전자기 소음을 찾고 줄이는 방법

Electromagnetic interference, or EMI, is one of the most common problems engineers encounter when developing electronic and industrial control systems. A PCB may work perfectly on the laboratory bench but begin to experience communication errors, unexpected resets, sensor noise, or intermittent operation after it is installed inside a machine. Why does this happen? The problem […]

PCB Ground Plane: Why It Matters for Signal Integrity and Power Stability

When designing a PCB, engineers often spend a lot of time thinking about signal traces and power traces. However, there is another path that is equally important: The return current path. A signal does not simply travel from one component to another and disappear. Current must complete a loop. For many PCB designs, a properly […]
