  • Page 69: Preventing Electrostatic Damage

    Removal and Replacement Preliminaries 4.4 Preventing Electrostatic Damage Many electronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structure determine the degree of sensitivity. Networks built into many integrated circuits provide some protection, but in many cases the discharge contains enough power to alter device parameters or melt silicon junctions.

  • Page 70: Workstation Precautions

    Place reusable electrostatic-sensitive parts from assemblies in protective packaging or nonconductive foam. Use transporters and conveyers made of antistatic belts and roller bushings. Ensure that mechanized equipment used for moving materials is wired to ground and that proper materials were selected to avoid static charging. When grounding is not possible, use an ionizer to dissipate electric charges.
