Electrostatic discharge (ESD) is a common natural phenomenon. When two materials with different electrostatic intensities rub against each other, electrostatic charges are generated. The effects of ESD on electrical and electronic equipment, devices or systems are everywhere. It is a very high degree of harmful electromagnetic energy. Only to improve the level of anti-static interference can ensure the safe use of electronic products.
ESD immunity test simulates the following two situations:
1) Direct application of discharge (application of the discharge directly to the EUT).
2) Indirect application of the discharge (application of the discharge to a coupling plane in the vicinity of the EUT to simulate personnel discharge to objects which are adjacent to the EUT).
