Static electricity is created all the time at home and at the workplace. In normal circumstances hand contact with a conductive material will discharge static from the body very rapidly.
This is ESD (Electro Static Discharge). Static electricity has become a major problem in the electronics industry. The presence of inherent ESD is not easy to detect. Product damage may go undetected at the production stage, but lead to failure at a later date.
Once the potential dangers of ESD damage are understood, effective methods of prevention can be put in place. All-inclusive protection from electrostatic discharge is a necessity whenever modern electronic devices are handled. An EPA (Electrostatic Protected Area) should always use ESD protected materials to prevent component damage. Protection should systematically extend from goods inwards areas to final test and packaging.
