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.
„
Transport products in static-safe containers, such as tubes, bags, or boxes to avoid hand contact.
„
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.
„
When handling or touching a sensitive component or assembly, ground yourself by touching the
chassis.
„
Avoid contact with pins, leads, or circuitry.
„
Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive
foam.
Personal Grounding Methods and Equipment
Use the following equipment to prevent static electricity damage to equipment:
„
Wrist straps are flexible straps with a maximum of one-megohm ± 10% resistance in the ground
cords. To provide a proper ground, wear the strap against bare skin. The ground cord must be
connected and fit snugly into the banana plug connector on the grounding mat or workstation.
„
Heel straps, toe straps, and boot straps can be used at standing workstations and are compatible
with most types of shoes or boots. On conductive floors or dissipative floor mats, use them on both
feet with a maximum of one-megohm ± 10% resistance between the operator and ground.
Grounding the Work Area
To prevent static damage at the work area:
„
Cover the work surface with approved static-dissipative material. Provide a wrist strap connected to
the work surface and properly grounded tools and equipment.
„
Use static-dissipative mats, foot straps, or air ionizers to give added protection.
NOTE 700 volts can degrade a product.
