6.2 Grounding Methods for ESD Prevention
Use one or more of the following grounding methods when handling or installing
electrostatic-sensitive devices:
● Use an ESD wrist strap that connects to a grounded work area or computer
chassis through a ground cable. The wrist strap must be scalable, and the
resistance of the ground cable must be at least 1 megohm (±10%). For
grounding purposes, wear the wrist strap tightly against your skin.
● Use a heel-grounded, toe-grounded, or shoe-grounded ESD strap when
working in a standing position. When standing on a conductive
oor or
electrostatic dissipative
oor mat, tie a strap on your feet.
● Use conductive maintenance tools.
● Use a folding tool mat that dissipates static electricity and a portable eld
service kit.
