What is ESD test? Electrostatic discharge immunity test is a basic EMC test . S tandard IEC61000-4-2 provide the immunity requirements and test methods for electrical and electronic equipment subjected to static electricity discharges, from operators directly, and to adjacent objects . T he standard establish a common and reproducible basis for evaluating the performance of electrical and electronic equipment when subjected to electrostatic discharges. Electrostatic discharge is a transfer of electric charge between bodies of different electrostatic potential in proximity or through direct contact. The standard IEC61000-4-2 does not intend to specify the tests to be applied to particular apparatus or system, it is to give a general basic reference to all concerned product . S o before conduct the test, an appropriate test level should be selected according to the product's characters and its working occasion. Contact discharge and air discharge methods The test leve...
