Electrostatic Discharge (ESD) Precautions
Electrostatic charges can damage the integrated circuits on printed circuit
boards. To prevent such damage from occurring, observe the following pre-
cautions during board unpacking and installation:
•
Stand on a static-free mat.
•
Wear a static strap to ensure that any accumulated electrostatic charge is dis-
charged from your body to ground.
•
Connect all equipment together, including the static-free mat, static strap, routing
nodes, and peripheral units.
•
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.
