notes
1. Use product-specific ESD procedures when they
exceed the requirements noted here.
2. Make sure that the ESD protective devices you
use have been certified (ISO 9000) as fully effec-
tive.
When handling ESD-sensitive parts:
Ÿ
Keep the parts in protective packages until they are
inserted into the product. . Avoid contact with other
people.
Ÿ
Wear a grounded wrist strap against your skin to
eliminate static on your body.
Ÿ
Prevent the part from touching your clothing. Most
clothing is insulative and retains a charge even when
you are wearing a wrist strap.
Ÿ
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.
Ÿ
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 oper-
ator safety and correct system function. Proper grounding
of the electrical outlet can be verified by a certified
electrician.
