METHODS OF GROUNDING

Use one or more of the following measures when handling or installing
Electrostatic-sensitive parts:

§

 

Use a wrist strap connected by a ground cord to a grounded workstation
or to the computer chassis. Wrist straps are flexible straps with a
minimum of 1 /- 10 percent resistance in the ground cords. To
provide a proper ground, wear the strap snug against the skin.

§

 

Use heelstraps, toestraps, or bootstraps at standing workstations. Wear
the straps on both feet when standing on conductive floors or
dissipating floor mats.

§

 

Use conductive field service mats.

§

 

Use a portable field service kit with a folding static-dissipating work
mat.
