Electrostatic Discharge Information
A sudden discharge of static electricity from your finger or other conductor can destroy staticsensitive 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 affected 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.

5.2.1 Generating Static

The following table shows that:
Different activities generate different amounts of static electricity. Static electricity increases as humidity decreases.
Relative Humidity Event Walking across carpet Walking across vinyl floor Motions of bench worker Removing bubble pack from PCB Packing PCBs in foam-lined box 55% 7,500 V 3,000 V 400 V 7,000 V 5,000 V 40% 15,000 V 5,000 V 800 V 20,000 V 11,000 V 10% 35,000 V 12,000 V 6,000 V 26,500 V 21,000 V
700 volts can degrade a product.
5.2.2 Preventing Electrostatic Damage to Equipment
Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of sensitivity. The following packaging and grounding precautions are necessary to prevent damage to electric components and accessories.
To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes. 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. Place items on a grounded surface before removing them from their container. 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.
5.2.3 Personal Grounding Methods and Equipment
Use the following equipment to prevent static electricity damage to equipment:

Routine Care

5.3.1 General Cleaning Safety Precautions
1. Never use solvents or flammable solutions to clean the computer. 2. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and then use the cloth on the component. 3. Always unplug the computer when cleaning with liquids or damp cloths. 4. Always unplug the computer before cleaning the keyboard, mouse, or air vents. 5. Disconnect the keyboard before cleaning it. 6. Wear safety glasses equipped with side shields when cleaning the keyboard.
5.3.2 Cleaning the Computer Case
Follow all safety precautions in Section 5.3.1, General Cleaning Safety Precautions, before cleaning the computer. To clean the computer case, follow the procedures described below:
To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab. For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping it with a cloth or swab dampened with clear water. For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed as the alcohol will evaporate quickly and not leave a residue. After cleaning, always wipe the unit with a clean, lint-free cloth. Occasionally clean the air vents on the computer. Lint and other foreign matter can block the vents and limit the airflow.
5.3.3 Cleaning the Keyboard
Follow all safety precautions in Section 5.3.1, General Cleaning Safety Precautions, before cleaning the keyboard. To clean the tops of the keys or the keyboard body, follow the procedures described in Section 5.3.2, Cleaning the Computer Case. When cleaning debris from under the keys, review all rules in Section 5.3.1, General Cleaning Safety Precautions, before following these procedures:
CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the keys.
Visible debris underneath or between the keys may be removed by vacuuming or shaking. Canned, pressurized air may be used to clean debris from under the keys. Caution should be used as too much air pressure can dislodge lubricants applied under the wide keys. If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool is available through many electronic supply outlets.
