The Not-So-Firm Guide to ESD Testing
Because ESD test techniques are not well established, it is important to understand the various parameters that have to be simulated, at a minimum, to perform an adequate test. On the basis of their possibility of interference to the spacecraft, the following items should be considered in designing tests:
a. Spark location.
b. Radiated fields or structure currents.
c. Area, thickness, and dielectric strength of the material.
d. Total charge involved in the event.
e. Breakdown voltage.
f. Current waveform (risetime, width, falltime, and rate of rise [in ampere per second]).
g. Voltage waveform (risetime, width, falltime, and rate of rise [in volt per second]).
