Capacitive discharge to ground of a flat metal disk with a pin contact
Abstract
Capacitance (C) and voltage (V) on a flat disk is calculated as a function of separation (d) from a ground plane. At large d, C and V are constants. C increases as 1/d and V goes to 0 at d=0, eliminating ESD. Adding a contact pin significantly increases ESD risk.
