Electrostatic Discharge Threat Environment Data Base and Recommended Baseline Stockpile-to-Target Sequence Specifications.

摘要

An extensive review of the existing data base on the human electrostatic discharge event has been conducted. Based on the data identified, a modified human ESD environment has been proposed for adoption into future STSs. This environment is based on the observed waveform now regarded by the ESD technical community as representing the worst-case stress to components, either electronic or ordnance, in terms of peak amplitude, risetime/riserate, and total pulse energy. The environment is defined by means of a linear passive circuit equivalent of the charged human body that is only slightly more complex than circuit models appearing in existing STSs. Values for the R, L, and C circuit elements are selected from the most reliable measured data found during the literature review in such a way as to result in a practical extreme environment, as is dictated by DOE-DNA TP 50-20, which defines the functions and format of an STS. The model produces an environment in good agreement with measured extreme human ESD events. 41 refs., 18 figs., 8 tabs. (ERA citation 14:004886)
