system board or component damage.

Electrostatic discharge information

A sudden discharge of static electricity from your nger or other conductor can destroy static-sensitive

devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device

exposed to electrostatic discharge (ESD) may not appear to be aected at all and can work perfectly

throughout a normal cycle. The device may function normally for a while, but it has been degraded in the

internal layers, reducing its life expectancy.

Networks built into many integrated circuits provide some protection, but in many cases, the discharge

contains enough power to alter device parameters or melt silicon junctions.

Electrostatic discharge information 11

Protect all electrostatic parts and assemblies with conductive or approved containers or packaging.

Keep electrostatic sensitive parts in their containers until they arrive at static-free stations.

Always be properly grounded when touching a sensitive component or assembly.

Avoid contact with pins, leads, or circuitry.

Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive

foam.

Grounding the work area

them only at static-free work areas.

Turn o power and input signals before inserting and removing connectors or test equipment.

Use xtures made of static-safe materials when xtures must directly contact dissipative surfaces.

Keep work area free of nonconductive materials such as ordinary plastic assembly aids and Styrofoam.

Use eld service tools, such as cutters, screwdrivers, and vacuums, that are conductive.
