When the sparks fly: ESD at Buerklin Elektronik

摘要

Each of us has experienced at some point what electrostatic discharge means: You touch a metallic object and it sends a tingle through your finger or even your whole body. From a physics point of view, an electrostatic discharge is a potential equalization of two differently charged bodies. This potential difference is caused, for example, by friction, which electrostatically charges the body - its potential is increased. If the charged body approaches or touches another body with a lower potential, the potentials are suddenly balanced out, causing a tingle, shock or even a spark. These are by no means small voltages: At a relative humidity of 10%, a person can be charged to over 35,000V by walking on a carpet alone.
