In this article we will discuss Typical Electrostatic discharge (ESD) Problems and Common Solutions. Electrostatic discharge (ESD) is a common phenomenon that is encountered on an everyday basis by many of us. It is the sudden flow of electrical energy between two objects of differing electrical potential (or charge). ESD is essentially a lightening bolt on a very small scale and, like a lightening bolt, the electrical energy will try to find a low impedance path to ground in order to equalise the electrical potential. Anybody who has walked across a carpeted floor and touched a metal doorknob may have felt or even seen a small spark jump from their hand to the metal doorknob.
