Electrostatic Discharge
A–2 SATA Hard Drive Installation Guide
Q Avoid touching pins, leads, or circuitry.
Q Always be properly grounded when touching a
static-sensitive component or assembly.
Grounding Methods
There are several methods for grounding. Use one or more
of the following measures when handling or installing
electrostatic-sensitive parts:
Q Use a wrist strap connected by a ground cord to a grounded
workstation or the computer chassis. Wrist straps are
flexible straps with a minimum of 1 meg. ohm +/- 10
percent resistance in the ground cords. To provide a proper
ground, wear the strap snug against the skin.
Q Use heelstraps, toestraps, or bootstraps at standing
workstations. Wear the straps on both feet when standing on
conductive floors or dissipating floor mats.
Q Use conductive field service tools.
Q Use a portable field service kit with a folding
static-dissipating work mat.
