What is electrostatic discharge immunity test

Electrostatic discharge immunity test is to simulate the human body contact (or close to) electronic equipment or components generated when the electrostatic discharge, the impact of electronic equipment test.

By discharge type:

Contact discharge

Simulation of charged objects in direct contact with the surface of the equipment after the discharge process.

Air discharge

Simulates the discharge process formed when a charged object carries enough charge and high enough voltage to break through the air between the voltage in the process of approaching the surface of the equipment.

According to the test method:

Direct discharge

Direct discharge to the subject equipment

Indirect discharge

Discharge to the coupling device near the subject equipment,
