•
Put the ESD wrist strap on your wrist. Connect the wrist band to
the system ground point. This discharges any static electricity in
your body to the machine.
•
Hold the ESD-sensitive part by its edge connector shroud
(cover); do not touch its pins. If you are unplugging a removable
module, use the correct tool.
•
Do not place the ESD-sensitive part on the machine cover or on
a metal table; if you need to put down the ESD-sensitive part for
any reason, 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. Install machine covers when you are not work-
ing on the machine, 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.
