Procedures for Handling Printed Circuit Boards
Static charges are present at all times and in all environments. Damage to
sensitive electronics occurs at lower voltage levels than people can sense.
Static damage may cause total failure or degrade the circuits’ performance
and can eventually lead to intermittent or total failure. Prevent component
damage by discharging static electricity to a ground. Follow the procedures
below.
Before touching, adjusting, or removing a printed circuit board (PCB),
wear a wrist strap grounded to the cabinet or enclosure ground point. If a
grounding wrist strap is not available, touch a grounded point within the
enclosure each time before touching a PCB or electronic assembly. An
example of a grounding point is the metal cabinet’s screws.
Caution
Limit the direct handling of the PCB to reduce the chance of damage.
Keep the PCB in a protective bag until it is installed. Use static
handling procedures before opening the bag and removing the circuit
board. Return all replaced PCBs to the static protective bag.
