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.
