Testing Specification
International standard defining the methods for measuring the electromagnetic immunity of integrated circuits. The protocols in iec 62132 cover frequencies ranging from 150 kilohertz to 1 gigahertz. It provides a framework for evaluating how semiconductors respond to conducted and radiated disturbances.
Measurement Method
Bulk current injection and direct power injection are the primary techniques specified. Each part of iec 62132 details a specific procedure, such as the use of a transverse electromagnetic cell or a workstation for radiated field evaluation. These tests identify the power levels at which a chip fails to perform its intended function.
Operational Criterion
Performance is graded by the severity of the malfunction observed during exposure. Compliance with iec 62132 requires the device to maintain a defined state, such as continuous operation or self-recovery without human intervention. Automotive suppliers rely on these ratings to ensure that engine control units and sensor interfaces remain stable in harsh electromagnetic environments.
Test setups must use specific printed circuit boards to ensure results are repeatable across different laboratories.
Application Scope
Silicon designers use the data to harden internal circuit nodes against transients. Because iec 62132 focuses on the component level, it aids in predicting the immunity of the final electronic assembly.
