As Will pointed out, if the bags are too conductive
(just like the black
conductive bags), they don't really protect against external ESD.
Why would this be? The idea is to dissipate very high voltages that
has almost low current behind them, because the gate dielectric in
MOSFETs is very thin and can be punctured by high voltages, so you need
to avoid large voltage differentials between pins. Higher conductivity
achieves that just as well.
I can "sorta" see what Will was talking about when too much current
flows too quickly, producing charges in nearby components via
electromagnetic induction. Is that the issue here?
