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 접지 설계: 노이즈, EMI 및 접지 반사 감소 방법

Introduction One of the most important parts of PCB design is also one of the most frequently misunderstood:  Ground. Many engineers initially think of ground as simply a connection to 0 V. In a real PCB, however, ground is also a current-return path. When current flows through a PCB trace, plane, via, connector, or cable, the resistance […]

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 […]
