Grounding guidelinesElectrostatic discharge damageElectronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structuredetermine the degree of sensitivity. Networks built into many integrated circuits provide someprotection, but in many cases, ESD contains enough power to alter device parameters or meltsilicon junctions.A discharge of static electricity from a finger or other conductor can destroy static-sensitive devices ormicrocircuitry. Even if the spark is neither felt nor heard, damage may have occurred.An electronic device exposed to ESD may not be affected at all and can work perfectly throughout anormal cycle. Or the device may function normally for a while, then degrade in the internal layers,reducing its life expectancy.CAUTION: To prevent damage to the tablet when you are removing or installing internalcomponents, observe these precautions:Keep components in their electrostatic-safe containers until you are ready to install them.Before touching an electronic component, discharge static electricity by using the guidelinesdescribed in this section.Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.If you remove a component, place it in an electrostatic-safe container.The following table shows how humidity affects the electrostatic voltage levels generated bydifferent activities.CAUTION:A product can be degraded by as little as 700 V.Typical electrostatic voltage levelsRelative humidityEvent810%40%55%Walking across carpet35,000 V15,000 V7,500 VWalking across vinyl floor12,000 V5,000 V3,000 VMotions of bench worker6,000 V800 V400 VRemoving DIPS from plastic tube2,000 V700 V400 VRemoving DIPS from vinyl tray11,500 V4,000 V2,000 VRemoving DIPS from Styrofoam14,500 V5,000 V3,500 VRemoving bubble pack from PCB26,500 V20,000 V7,000 VPacking PCBs in foam-lined box21,000 V11,000 V5,000 VChapter 4 Removal and replacement preliminary requirements

Packaging and transporting guidelinesFollow these grounding guidelines when packaging and transporting equipment: To avoid hand contact, transport products in static-safe tubes, bags, or boxes. Protect ESD-sensitive parts and assemblies with conductive or approved containers orpackaging. Keep ESD-sensitive parts in their containers until the parts arrive at static-free workstations. Place items on a grounded surface before removing items from their containers. Always be properly grounded when touching a component or assembly. Store reusable ESD-sensitive parts from assemblies in protective packaging ornonconductive foam. Use transporters and conveyors made of antistatic belts and roller bushings. Be sure thatmechanized equipment used for moving materials is wired to ground and that proper materialsare selected to avoid static charging. When grounding is not possible, use an ionizer to dissipateelectric charges.Workstation guidelinesFollow these grounding workstation guidelines: Cover the workstation with approved static-shielding material. Use a wrist strap connected to a properly grounded work surface and use properly groundedtools and equipment. Use conductive field service tools, such as cutters, screw drivers, and vacuums. When fixtures must directly contact dissipative surfaces, use fixtures made only of staticsafe materials. Keep the work area free of nonconductive materials, such as ordinary plastic assembly aidsand Styrofoam. Handle ESD-sensitive components, parts, and assemblies by the case or PCM laminate. Handlethese items only at static-free workstations. Avoid contact with pins, leads, or circuitry. Turn off power and input signals before inserting or removing connectors or test equipment.Grounding guidelines9

Equipment guidelinesGrounding equipment must include either a wrist strap or a foot strap at a grounded workstation. When seated, wear a wrist strap connected to a grounded system. Wrist straps are flexiblestraps with a minimum of one megohm 10% resistance in the ground cords. To provide properground, wear a strap snugly against the skin at all times. On grounded mats with banana-plugconnectors, use alligator clips to connect a wrist strap. When standing, use foot straps and a grounded floor mat. Foot straps (heel, toe, or boot straps)can be used at standing workstations and are compatible with most types of shoes or boots. Onconductive floors or dissipative floor mats, use foot straps on both feet with a minimum of onemegohm resistance between the operator and ground. To be effective, the conductive must beworn in contact with the skin.The following grounding equipment is recommended to prevent electrostatic damage: Antistatic tape Antistatic smocks, aprons, and sleeve protectors Conductive bins and other assembly or soldering aids Nonconductive foam Conductive tabletop workstations with ground cords of one megohm resistance Static-dissipative tables or floor mats with hard ties to the ground Field service kits Static awareness labels Material-handling packages Nonconductive plastic bags, tubes, or boxes Metal tote boxes Electrostatic voltage levels and protective materialsThe following table lists the shielding protection provided by antistatic bags and floor mats.10MaterialUseVoltage protection levelAntistatic plasticsBags1,500 VCarbon-loaded plasticFloor mats7,500 VMetallized laminateFloor mats5,000 VChapter 4 Removal and replacement preliminary requirements
