Electrostatic Discharge (ESD)

 

ESD

Electrostatic discharge (ESD) can occur when there is a buildup of an electric charge (static electricity) that exists on a surface that comes into contact with another, differently charged surface. ESD can cause damage to computer equipment if not discharged properly. Follow proper handling guidelines, be aware of environmental issues, and use equipment that stabilizes power to prevent equipment damage and data loss.

• Keep all components in antistatic bags until you are ready to install them.

• Use grounded mats on workbenches.

• Use grounded floor mats in work areas.

• Use antistatic wrist straps when working inside computers.

At least 3,000 volts of static electricity must build up before a person can feel ESD. For example, static electricity can build upon you as you walk across a carpeted floor. When you touch another person, you both receive a shock. If the discharge causes pain or makes a noise, the charge was probably above 10,000 volts. By comparison, less than 30 volts of static electricity can damage a computer component. The static buildup can be discharged by touching a grounded object prior to touching any electronic equipment. This is known as self-grounding

ESD can cause permanent damage to electrical components. Follow these recommendations to help prevent ESD damage:
