Electrostatic Discharge (ESD) Precautions
Electrostatic charges can damage the integrated circuits on printed circuit boards. To
prevent such damage from occurring, observe the following precautions during board
unpacking and installation:
• Stand on a static-free mat.
• Wear a static strap to ensure that any accumulated electrostatic charge is discharged
from your body to ground.
• Create a common ground for the equipment you are working on by connecting the
static-free mat, static strap, and peripheral units to that piece of equipment.
• Keep uninstalled printed circuit boards in their protective antistatic bags.
• Handle printed circuit boards by their edges, once you have removed them from their
protective antistatic bags.
