Electrostatic discharge (ESD) poses a significant threat to electronic components and systems across multiple industries. ESD events, which involve the sudden flow of electricity between two charged objects, can cause latent failures, operational disruptions, or permanent damage to sensitive circuitry. To mitigate these risks, standardized ESD testing methodologies have been developed, requiring specialized equipment capable of simulating and evaluating discharge events under controlled conditions.

This article examines the fundamental principles of ESD testing, the critical features of advanced ESD test equipment, and the applications of such systems in industries ranging from medical devices to automotive electronics. A particular focus is placed on the LISUN ESD61000-2, a high-precision Simulator ESD designed to meet international standards while offering enhanced repeatability and user configurability.

ESD testing is governed by several standardized models, each simulating distinct real-world discharge scenarios:

Itu LISUN ESD61000-2 complies with IEC 61000-4-2, ensuring accurate HBM waveform generation with discharge voltages ranging from 0,1 kV hingga 30 kV. Its dual-polarity (±) output and adjustable rise time (0.7–1 ns) enable precise replication of real-world ESD events.

Itu ESD61000-2 integrates advanced features to meet the demands of high-stakes compliance testing:

ESD resilience is critical for implantable electronics and diagnostic equipment. The ESD61000-2 validates compliance with IEC 60601-1-2, ensuring patient safety and operational reliability during electrostatic events.

Modern vehicles incorporate sensitive ADAS (Advanced Driver Assistance Systems) and infotainment modules. Per ISO 10605, the ESD61000-2 evaluates component immunity to discharges up to 25 kV, simulating static buildup from occupant movement.

High-voltage environments, such as power converters and motor drives, require rigorous ESD testing. The simulator’s 30 kV range accommodates industrial ESD threats, including discharges from insulating materials.

LED drivers and control modules are susceptible to ESD-induced failures. Using the ESD61000-2, manufacturers subject drivers to 8 kV contact discharges per IEC 62031, identifying weak points in surge protection circuits. Post-test analysis revealed a 30% improvement in failure rates after design revisions informed by simulator data.

Q1: What is the maximum test voltage for automotive applications using the ESD61000-2?
The simulator supports up to 30 kV, though ISO 10605 typically mandates 15 kV (air) and 8 kV (contact) for most automotive components.

Q2: How does the ESD61000-2 ensure waveform accuracy?
Calibrated current sensors and high-speed oscilloscopes validate each pulse against IEC 61000-4-2’s 30/60 ns parameters.

Q3: Can the system test non-electronic components?
Yes, electrostatic shielding materials (e.g., for aerospace composites) are evaluated using contact discharge modes.

Q4: What industries require CDM testing instead of HBM?
Semiconductor manufacturing and high-density PCB assemblies often prioritize CDM per JESD22-C101.

Q5: Is the ESD61000-2 suitable for MIL-STD-461G testing?
While optimized for IEC/ISO standards, it can be configured for military ESD scenarios with additional fixturing.

This technical exploration underscores the indispensable role of precision ESD test equipment in safeguarding electronic systems across diverse sectors. The LISUN ESD61000-2 exemplifies the integration of rigorous standards compliance with operational versatility, addressing the evolving demands of modern ESD qualification.
