Aspects of Behavior Regarding Certain Electronic Equipment Subject to Electrostatic Discharge

Abstract

Electrical discharge due to human operators may cause disturbances with very fast variation reaching the sensitive equipment by conduction and radiation and can affect and even destroy them. Therefore, between a human, possible to load electrostatic voltages of 10-15kV ordinal, and an electronic device (computer, laptop, memory stick, etc.), system connected to the grounding, an electrostatic discharge can occur as a result of electric charging (electrification) the person wearing clothes made of synthetic fibers, due to friction with the air. This paper proposes a study of the transient arrangement produced by human electrostatic discharge and the disruptive or destructive effects that may occur. Experimental tests have been performed to determine the degree of immunity to electrostatic discharge (ESD) into the air and through direct contact, in accordance with the regulations in force, in the specialized laboratory of ICMET Craiova, subjecting a memory stick and a wireless Internet connection stick to electrostatic discharge. The results obtained revealed the individualized behavior for each device tested. images
