What Is Esd Testing

An electrostatic discharge test is a test to evaluate the durability of electronic devices when electrostatic discharge occurs when a person touches them. In winter, when you touch a doorknob or try to get out of a car, you may feel a “buzz” of static electricity discharge.

How is ESD testing performed?

The testing conducted consists of applying one positive and one negative pulse to the component, allowing a 0.3 second interval between pulses. A set of devices is exposed to these pulses at a given voltage level and pin grounding combinations; the device is tested for full static and dynamic parameters.

Why ESD test is done?

ESD testing is an electromagnetic compatibility test (EMC test). ESD testing simulates various electrostatic impacts that equipment might experience either during transit or operation. An electrostatic discharge test determines whether a product is in compliance with its ESD protective area and procedures.
