Sheilding does nothing for ESD protection. ESD damage can be induced
from power leads as well as signal inputs and outputs. In fact more
damage is done with ESD discharge with ground rising above the
positive supply potential during an ESD event. A 4KV discharge is
easily encountered with handling of any componnent or assembly without
even the person knowing it happens. The human body can impart as much
as a 16KV discharge during an ESD event.
