  • Page 8: Grounding Guidelines

    Grounding guidelines Electrostatic discharge damage Electronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structure determine the degree of sensitivity.

A discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or microcircuitry.
