ESD (electrostatic discharge) in Metal Enclosures
Above: Illustration of the coupling of an ESD discharge to an electronic
circuit for (a) metal enclosure with apertures and (b) plastic enclosure.
Failure Modes due to (electrostatic discharge)
Above: Direct discharge into circuit; Direct discharge into ground system;
Indirect discharge
Solutions:
- Common failure modes: change of instrument state (front panel control), CPU reset, instrument lockup, loss of data.
- Use shielding, reroute cables, separate receptor circuits.
