Prevent ESD Damage to Sensitive Electronic Devices
What is ESD?Electrostatic discharge (ESD) is a stream of electricity that occurs suddenly between electrically charged items through contact, electrical breakdown, or an electrical short. There are several reasons that this situation can occur, but the most common is a power outage and subsequent power surge caused by an electrical storm. When static electricity builds up, the ESD can damage sensitive electronic devices, burn out electrical pathways and even cause fires and explosions if a spark is formed near flammable substances. Manufacturers of electronic devices advise protecting them against ESD to avoid failure or permanent damage to circuit boards from the higher voltages. Most electronic devices are built with some ESD protection from day-to-day usage, however to protect devices at your home or office during more intense situations further steps should be taken.
ESD SymbolsThere are three primary symbols to denote ESD awareness as defined in ANSI/ESD S8.1: - Black triangle with hand and slash through it is often posted with a yellow background, this symbol denotes that a device is susceptible to ESD, and needs to be packaged accordingly. These devices should also be protected once placed in your home or office.
- Black triangle with hand and arc around it--This version of the symbol denotes products that are made to protect sensitive devices from electrostatic discharge. These protective items include package, clothing and equipment.
- Bold circle with two bold concentric circles and the words ESD COMMON POINT GROUND inside--This symbol designates an ESD ground point where a plug or connector can be attached. This symbol is recommended to be colored black or white on green.
