v
Prevent the part from touching your clothing. Most clothing is insulative and
retains a charge even when you are wearing a wrist strap.
v
Use the black side of a grounded work mat to provide a static-free work surface.
The mat is especially useful when handling ESD-sensitive devices.
v
Select a grounding system, such as those listed below, to provide protection that
meets the specific service requirement.
Note: The use of a grounding system is desirable but not required to protect
against ESD damage.
– Attach the ESD ground clip to any frame ground, ground braid, or green-wire
ground.
– Use an ESD common ground or reference point when working on a
double-insulated or battery-operated system. You can use coax or
connector-outside shells on these systems.
– Use the round ground-prong of the ac plug on ac-operated computers.
Grounding requirements
Electrical grounding of the computer is required for operator safety and correct
system function. Proper grounding of the electrical outlet can be verified by a
certified electrician.
