EMI shielding and RF shielding are often used interchangeably, but they solve different interference challenges. EMI shielding protects across a broad frequency range, including low-frequency magnetic and high-frequency digital noise, while RF shielding targets specific high-frequency signals in telecom, medical, and defense systems. The biggest engineering failures usually occur at seams, gaps, and grounding—not panel materials. Selecting the correct shielding solution requires identifying frequency range, required attenuation (dB), compliance standards, environmental exposure, and mechanical design constraints. Planning shielding at the prototype stage prevents costly compliance failures, redesign loops, and unexpected field performance issues.
