Why is ESD hazardous to the technician?

Why is ESD hazardous to the technician?

ESD can damage or destroy sensitive electronic components, erase or alter magnetic media, or set off explosions or fires in flammable environments. Each year, an estimated $40 billion in losses from ESD damage occur in the electronics industry alone.

Why is it important to be aware from electrostatic discharge or ESD?

Costly Effects of ESD While you can feel electrostatic discharges of 3,000 volts, smaller charges are below the threshold of human sensation. Unfortunately, smaller charges can and do damage semiconductor devices. You should be aware of the relative sensitivity to ESD damage of devices you may be working with.

Why is electrostatic discharge important?

The control of electrostatic discharge is an important aspect when manufacturing, assembling and repairing devices that employ electronics. Electrostatic discharges can damage an electronic component at any stage of its production or application if not controlled.

Why is it important to perform an electrostatic discharge before performing the computer hardware assembly?

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.

How can we 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.

How can we prevent electrostatic discharge?

Keep electrostatic-sensitive parts in their containers until they arrive at static-protected workstations. Place parts in a static-protected area before removing them from their containers. Avoid touching pins, leads, or circuitry. Always be properly grounded when touching a static-sensitive component or assembly.

How can electrostatic discharge from the body?

Ground Your Body The fastest way to get rid of static electricity in the body is to let the electricity do what it wants – discharge from your body into the ground. To allow this, touch any conductive material not isolated from the ground such as the screw on a light switch’s panel or a metal streetlight pole.

How do you prevent electrostatic discharge?

How does electrostatic discharge occur?

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). ESD generated from the human body can be of the order of several thousand volts.

What are the electrostatic discharge tools?

The most common kinds of ESD equipment are:

• Antistatic work benches.
• Grounding cords.
• Antistatic tools.
• Antistatic gloves.
• ESD rubber matting.
• Antistatic clothing.

What are the causes of ESD?

Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects caused by contact, an electrical short or dielectric breakdown. A buildup of static electricity can be caused by tribocharging or by electrostatic induction.

Why is electrostatic discharge so important to electronics?

The age of electronics brought with it new problems associated with static electricity and electrostatic discharge. Electronic devices became smaller and faster and their sensitivity to ESD increased. Today, ESD impacts productivity and product reliability in virtually every aspect of the electronics environment.

What happens when you touch an electrostatic discharge sensitive?

When a statically-charged person or object touches an electrostatic discharge sensitive (ESDS) device, there is a possibility that the electrostatic charge could be drained through sensitive circuitry in the device.

What causes electrostatic discharge ( ESD ) in avionics?

Another cause of ESD damage is through electrostatic induction. This occurs when an electrically-charged object is placed near a conductive object isolated from ground. The presence of the charged object creates an electrostatic field that causes electrical charges on the surface of the other object to redistribute.

What should I do if I have electrostatic discharge?

• When troubleshooting electronic equipment, always wear a static wrist strap that’s grounded to the frame of the device. Also, wear the wrist strap when handling printed circuit boards. • Treat carpets and floors with compounds that reduce the buildup of static charges. • Use static floor mats where necessary.
