What Is Electrostatic Discharge Coatings (ESD)
ESD stands for Electro-Static Discharge, it refers to the transfer of static energy between bodies to stresses that are caused by direct contact or induced by an electrostatic field.
Electrostatic discharges (ESD) are short-term, transient discharges. Such discharges can then occur between solid, liquid and gaseous substances if they have different charges. They are usually accompanied by sparks or light effects.
When you walk through a rug and you touch a metal knob on a door, you experience a slight clash in your fingers with static energy. If the same ESD occurs on a data network computer, the equipment may be damaged or destroyed.
Damage caused by electrostatic discharges occurs most frequently when printed circuit boards are handled and transported on metal supports.
Electromagnetic interference (EMI) shields and connectors are integral components of metal support, and help protect ESD circuits.
However, it is best to have ESD protection devices when handling circuit boards.
In summary, ESD damage (electrostatic discharge) occurs because of the following:
- Direct electrostatic discharge to the device.
- Electrostatic discharge of the device.
- Field-induced downloads.
- Electrostatic discharge damage also occurs without knowing when inspecting, classifying or installing electronic devices.
