Overview
IEC TS 62132-9:2014 is an important technical specification from the International Electrotechnical Commission (IEC) focused on the measurement of electromagnetic immunity of integrated circuits (ICs). Specifically, it addresses the measurement of radiated immunity using the surface scan method. This standard provides detailed test procedures to evaluate how near-field electric, magnetic, or electromagnetic disturbances affect ICs. Targeted at IC developers and test engineers, it supports architectural analysis such as floor planning and power distribution optimization to enhance IC design robustness.
The surface scan method applies to ICs mounted on any accessible circuit board, enabling a spatially resolved mapping of sensitivity to electromagnetic interference (EMI). This mapping helps identify vulnerable regions on the IC surface when exposed to electromagnetic disturbances up to 6 GHz frequency.
