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.
