ESD Testing Equipment Standards & Methods Air & Contact
Electrostatic discharge or ESDcan be thought of as the build up of potential charge between to different objects which can be transferred through contact or by air This post will provide a brief overview of ESD from a broad EMI compliance stand point including testing overview methods of discharge and brief walk through of com…Test & Verification Equipment
ESD Testing – Air Discharge The same generator is used for the air discharge method, but with a rounded rather than a pointed probe tip, The capacitor is charged to the desired level as before, but the voltage is now continuously applied to the probe, which is held away from the EUT,
alternate test methodology known as air discharge for cases where contact discharge testing is not possible In the air discharge test the ESD test gun is brought close to the device under test until a discharge occurs The standards are defined so that each level is considered equivalent – a Level 4 contact discharge of 8 kV is considered equivalent to a 15 kV air discharge, IEC 61000-4-2 ESD …

Air-discharge testing In air-discharge testing, the relay in the ESD gun that initiates contact discharge remains closed throughout the test, The capacitance in the ESD gun and the tip of the ESD gun are charged simultaneously, The tip of the ESD gun is then moved toward the intended stress point until an arc forms or the gun’s tip touches the system being stressed, Air-discharge testing is …

ESD Testing
The air discharge is the method of testing in which the charged electrode of the test generator is moved towards the EUT until it touches the EUT, During this a discharge is activated by a spark, The IEC 61000-4-2 standard says “Contact discharge is the preferred test method,

Air discharge ESD test and measurement has been an inconsistent task due to the difficulty of holding the ESD simulator gun and zapping the same spot, leading to inconsistencies of the ESD discharge waveforms generated by different ESD gun designs, The loosely controlled IEC and ISO standards did not specify air discharge waveform parameters, However, the air discharge waveform is …
