IEC 61340-3-2: Methods for Simulation of Electrostatic Effects - Machine model (MM) Electrostatic Discharge Test Waveforms

The purpose of this standard is to establish a test model that will replicate MM failures and will define the MM transient current discharge waveform and all necessary test parameters to ensure reliable, reproducible test results. Reproducible data will allow accurate comparisons of MM ESD sensitivity levels.

Abstract

Describes the discharge current waveforms used to simulate machine model (MM) electrostatic discharges (ESD) and the basic requirements for equipment used to develop and verify these waveforms. This standard covers MM ESD waveforms for use in general test methods and for application to materials or objects, electronic components and other items for ESD withstand test or performance evaluation purposes. The specific application of these MM ESD waveforms to non-powered semiconductor devices is covered in IEC 60749-27. The major change of this document is that it no longer contains the application to semiconductor devices.

ESD Generator Requirements

Most current ESD simulators have easily interchangeable discharge networks allowing for custom Resitance/Capacitance values. The Machine Model requirements for IEC 61340-3-2 are 200pF and 0 Ohms resistance.
