chapter 4 R EMOVAL AND R EPLACEMENT P RELIMINARIES This chapter provides essential information for proper and safe removal and replacement service. 4.1 Tools Required You will need the following tools to complete the removal and replacement procedures: ■ ■ Magnetic Torx T-8 screwdriver (for all screws unless otherwise specified) 9/32-inch socket for bushing guides 4.
Cables and Connectors Cables must be handled with extreme care to avoid damage. Apply only the tension required to unseat or seat the cables during removal and insertion. Handle cables by the connector whenever possible. In all cases, avoid bending, twisting, or tearing cables. Ensure that cables are routed in such a way that they cannot be caught or snagged by parts being removed or replaced. Handle flex cables with extreme care; they tear easily.
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.
Workstation Precautions Use the following grounding precautions at workstations: ■ ■ ■ ■ ■ ■ ■ ■ 4-4 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.
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. To provide proper ground, a strap must be worn snug against the skin. On grounded mats with banana-plug connectors, connect a wrist strap with alligator clips.
Electrostatic Voltage Levels and Protective Materials Table 4-1 shows how humidity affects the electrostatic voltage levels generated by different activities.
