Handling ESD-Sensitive Parts
Many electronic products use parts that are known to be sensitive to
electrostatic discharge (ESD). To prevent damage to ESD-sensitive
parts, follow the instructions below in addition to all the usual pre-
cautions, such as turning off power before removing logic boards:
•
Keep the ESD-sensitive part in its original shipping container (a
special "ESD bag") until you are ready to install the part into the
machine.
•
Make the least-possible movements with your body to prevent
an increase of static electricity from clothing fibers, carpets, and
furniture.
