Hi,
A conductive surface wired to ground and to worker touches sensitive semiconducting components. Some components create high voltage. If ground surface touches high voltage comonents, worker is protected by megaohm resistor in wrist strap, but other components lie between high voltage component and ground wire! Thus, sensitive semiconducting components will be destroyed by great current from high voltage in ground short. Assume aluminum is the conducting surface. Could another surface material still dissapate ESD to ground but prevent great current from high voltage discharge? Thanks.
