Handling Printed Circuit Boards

ESD damage to unprotected sensitive devices may occur at any time. ESD events can occur far below
the threshold of human sensitivity. Follow this sequence when it becomes necessary to install or remove
a circuit board:
1. After you are connected to the grounded wrist strap, remove the circuit board from the frame and
place it on a static controlled surface (grounded floor or table mat).
2. Remove the replacement circuit board from the static-shielding bag or clamshell and insert it into the
equipment.
3. Place the original board into the shielding bag or clamshell and seal it with a label.
4. Do not put repair tags inside the shielding bag or clamshell.
5. Disconnect the wrist strap.
