  • Page 56: Preventing Electrostatic Damage

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

  • Page 57: Workstation Precautions

    Workstation Precautions Use the following grounding precautions at workstations: Cover the workstation with approved static-dissipative material (refer to Table 4-2 later in this chapter). Use a wrist strap connected to a properly grounded work surface and use properly grounded tools and equipment. Use field service tools, such as cutters, screwdrivers, and vacuums that are conductive.

  • Page 58: Grounding Equipmemt Amd Methods

    Grounding Equipment and Methods Grounding equipment must include either a wrist strap or a foot strap at a grounded workstation. When seated, wear a wrist strap connected to a grounded system. Wrist straps are flexible straps with a minimum of one megohm ±10% resistance in the ground cords.
