Chapter 6 Removal and Replacement Preliminaries This chapter provides general service information for the Compaq Armada 1500 Family of Personal Computers. Adherence to the procedures and precautions described in this chapter is essential for proper service. 6.1 Electrostatic Discharge A sudden discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or microcircuitry.
PAGE 80
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Preventing Electrostatic Damage to Equipment Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of sensitivity. The following proper packaging and grounding precautions are necessary to prevent damage: ■ Protect all electrostatic parts and assemblies with conductive or approved containers or packaging.
PAGE 81
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Preventing Damage to Drives To prevent static damage to hard drives, use the following precautions: ■ Handle drives gently, using static-guarding techniques. ■ Store drives in the original shipping containers. ■ Avoid dropping drives from any height onto any surface. ■ Handle drives on surfaces that have at least one inch of shockproof foam. ■ Always place drives with the PCB assembly-side down on the foam.
