FRONT_2.1 General IBM Electro-Static Discharge (ESD) Instructions
These are general instructions for handling ESD sensitive parts. Any part
containing transistors or ICs should be considered ESD Sensitive. Use
product specific ESD procedures when they exceed the requirements noted
here. ESD damage can occur when there is a difference in charge between
objects. We can protect against ESD damage, by equalizing the charge so
that the machine, the part, the work mat and the person handling the part
are all at the same charge. Ground is desirable but not required to
protect against ESD damage. The wrist band must be worn against the skin.
The grounding cord system should be selected to provide protection for the
specific service requirement. If an ESD sensitive part is swapped, the
mat must be used to provide an ESD safe work surface to protect the part
removed from the product. The mat may not be required for a simple
insertion. The mat may be used as a ESD protective container for swapping
parts between machines. The mat should be used with the BLACK side up.
The ESD ground clip can be attached to any frame ground, ground braid or
green wire ground. For products that are double insulated, or battery
operated, an ESD common ground or reference point should be used. The
round ground prong on the AC plug, can be used on AC operated products.
Coax or connector outside shells can be used on double insulated or
battery operated products.
ESD sensitive parts must not touch any part of your clothing. Most
clothing is insulative and retains a charge even when you are wearing a
wrist strap. Avoid contact with other people when handling ESD sensitive
parts. Keep ESD sensitive parts in protective packages until they are
inserted into the product.
