6-1 Static-Sensitive Devices
Electrostatic discharge (ESD) can damage electronic com ponents. To prevent
damage to any printed circuit boards (PCBs), it is important to handle them very
carefully. The following measures are generally sufficient to protect your equipment
from ESD damage.
Precautions
•
Use a grounded wrist strap designed to prevent static discharge.
•
Touch a grounded metal object before removing any board from its antistatic bag.
•
Handle a board by its edges only; do not touch its components, peripheral chips,
memory modules or gold contacts.
•
When handling chips or modules, avoid touching their pins.
•
Put expansion cards and peripherals back into their antistatic bags when not
in use.
•
For grounding purposes, make sure your computer chassis provides excellent
conductivity between the power supply, the case, the mounting fasteners and
the serverboard.
