IEC EN 61340-3-1 Electrostatic - Test for Simulation of Electrostatic Effects

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 61340-3-1 testing. This standard describes the discharge current waveforms used to describe the HBM and the basic equipment requirements used to develop these waveforms.

IEC EN 61340-3-1 Electrostatic - Test for Simulation of Electrostatic Effects

Test parameters are defined to test and classify electrostatic discharge (ESD) sensitivity of non-electrical devices to HBM. The purpose of this standard is to establish a test model that will repeat HBM (human body model) faults and define the HBM transient current discharge waveform and all required test parameters to provide reliable, repeatable test results. Reproducible data allow accurate comparison of HBM ESD susceptibility levels.

Equipment capable of verifying the HBM current waveform is defined in this standard. This equipment includes, but is not limited to, a waveform recording system, a high voltage resistor, and a current converter.

The lead length (short wire or resistor) of the rating loads should be as short as possible and consistent with connecting the rating load to the appropriate reference terminals as it passes through the current converter.

Evaluating the ESD robustness of a UUT with electrical terminals will often require classifying the terminals into different types, eg input, output, power supply, or ground. Each non-powered terminal should then be tested (one by one) against the power supply or ground terminals.

If UUTs with electrical terminals are evaluated, its purpose should be to detect the weakest pin combination and fault threshold for the HBM. Therefore, UUTs that do not have many electrical terminals are usually tested by HBM for all pin combinations. However, in the case of UUTs with a large number of electrical terminals, it is possible to select the pin combination as a pin group for testing.
