ESET Products Electrostatic Discharge Christmas

Most products in electronic packaging labels and warnings are where we are warned that the device is sensitive to electrostatic discharge or ESD as best known, hence derive two very interesting and important questions.

What is Electrostatic Discharge?

is the sudden and rapid transfer of electric charge from one object to another when there is a difference in potential, there are two ways in which an object can be loaded:

When two materials with different properties are brought into contact, the electrons are transferred from one material to another, leaving them loaded with positive and negative polarities. This type of load is called triboelectric or friction and the example known and experienced by everyone is walking across a carpet and feel a shock when touching a metal like a door knob, in this case were charged in a triboelectric to have contact with the carpet and electrostatic discharge (transfer) took play out when the knob.

The second mechanism is the induction load works on the known principle of "opposites attract, repel, this means that if two objects are not in contact, their electrostatic fields are loaded and can lead the charge separation, again taking a positive and negative charged material.

What happens when a device is sensitive to ESD is damaged?

There are two types of damage: the fatal which means that the drive dies or latent damage where the device is damaged.

The latent damage is more expensive because it is very difficult to detect and the device may pass the different tests of inspection. The fact that this damage means that at some point, while operating the device stops working.
