3.2.1 Handling ESD-sensitive parts

To prevent damage to ESD-sensitive parts, follow the instructions below in addition to all the usual
precautions, such as turning off power before removing logic cards:

Keep the ESD-sensitive part in its original shipping
ready to be installed.

Make the least-possible body movements to prevent an increase of static electricity from clothing
fibers, carpets, and furniture.

Put the ESD wrist strap on your wrist. Connect the wrist band to the system ground point
discharges any static electricity in your body to ground.


Hold the ESD-sensitive part by its edges; do not touch its pins. If a
then use the correct tool.

Do not place the ESD-sensitive part on insulating or on a metal table; if the ESD-sensitive part needs to be put
down for any reason, then first put it into its special bag.

Machine covers and metal tables are electrical grounds. They increase the risk of damage
because they make a discharge path from your body through the ESD-sensitive part. (Large metal
objects can be discharge paths without being grounded.)

Prevent ESD-sensitive parts from being accidentally touched by other personnel and do not put
unprotected ESD-sensitive parts on a table.

If possible, keep all ESD-sensitive parts in a grounded metal cabinet (case).

Be extra careful in working with ESD-sensitive parts when cold-weather heating is used
because low humidity increases static electricity
