Abstract
Human-generated ESD current waveshapes are predicted under contact
discharge and arc discharge conditions. The uncertainties connected
to man's posture and proximity to the victim are carefully examined.
The adopted human body model is devised to be composed of 11 elemental
blocks and treated by the diakoptic method in analogy with network
theory. The set of given leakage capacitances, in conjunction with
the resistances and inductances as serial parameters, forms a complex
RLC network. The assembly includes the grounded or ungrounded victim
and image elements due to the presence of the plane and a nearby
vertical wall. A PSPICE software allows the discharge scenario to
be evaluated. New insight into the complex charge transfer is thus
gained, which is combined with arc discharge performances. This careful
analytical interpretation of the ESD phenomenon could contribute
to in-progress standardization.
