Why ESD protection is needed in electronic circuits?

Protecting electronic devices and components that are sensitive to electrostatic discharge (ESD) is very important in manufacturing processes or environments. ESD control products are needed in order to prevent damage from the electrical charges that accumulate during critical manufacturing processes.

Why do we need ESD protection?

Protecting against the effects of electrostatic discharge is an essential requirement for any manufacture, home construction, service, repair and any other area in contact with electronic boards and components. … This means that it is essential to protect electronics equipment from the effects of ESD.

What is ESD and why is it important?

The Importance of ESD in the manufacturing industry

It is the heat from ESD which is the greatest threat to electrical components. If an ESD event occurs this can cause immediate or delayed damage. The delayed damage we often refer to as a ‘latent defect’.

How do you protect a circuit from ESD?

To protect sensitive circuitry from electrical overstress failures, ESD protection diodes are connected to each signal line between the interface connector and the IC .

Is ESD really a problem?

In the industry, it is referred to as Electro-Static Discharge (ESD) and is far more of a problem now than it has ever been; although it has been mitigated somewhat by the fairly recent widespread adoption of policies and procedures that help to lower the likelihood of ESD damage to products.

What is ESD example?

Electrostatic discharge (ESD) is the release of static electricity when two objects come into contact. Familiar examples of ESD include the shock we receive when we walk across a carpet and touch a metal doorknob and the static electricity we feel after drying clothes in a clothes dryer.

How many volts can damage an electronic component?

Static electricity can damage electronic equipment without the technician’s knowledge. The average person requires a static discharge of 3,000 volts before he or she feels it. An electronic component can be damaged with as little as 30 volts.

What is the full form of ESD?

When two electrically charged objects, such as the human body and an electronic device come into contact with each other, static electricity is discharged. This phenomenon is called ESD (Electrostatic Discharge).

How can you prevent ESD?

Preventing electrostatic discharge

  1. Avoid hand contact by transporting and storing products in static-safe containers.
  2. Keep electrostatic-sensitive parts in their containers until they arrive at static-protected workstations.
  3. Place parts in a static-protected area before removing them from their containers.

What is ESD in computer?

Electrostatic discharge (ESD) events can harm electronic components inside your computer. Under certain conditions, ESD may build up on your body or an object, such as a peripheral, and then discharge into another object, such as your computer.

Where should ESD diodes be placed?

In other words, the ESD protection diode must be placed as close to the pin that it is protecting as possible and its connection to the reference plane must be made as close to the anode pin as possible.
