Shielding Can Design in PCB Design: Principles, Techniques, and Best Practices
Abstract In modern electronic circuits, electromagnetic interference (EMI) and radio frequency interference (RFI) are critical challenges that can degrade signal integrity and system performance. Shielding cans (also known as EMI shields or RF shields) are widely used in printed circuit board (PCB) designs to mitigate these issues. This article explores the fundamentals of shielding can…
