Appendix A: Electrostatic
sensitive device (ESD)
Electrostatic discharge (ESD) is the transfer, between bodies, of an
electrostatic charge caused by direct contact or induced by an
electrostatic field.
The most common cause of ESD is physical contact. Touching an object
can cause a discharge of electrostatic energy
—
ESD! If the charge is
sufficient and occurs near electronic components, it can damage or
destroy those components.
In some cases, damage is instantaneous and an immediate malfunction
occurs. However, symptoms are not always immediat; performance
may be marginal or seemingly normal for an indefinite period of time,
followed by a sudden failure.
To eliminate potential ESD damage, review the following guidelines:
 Handle boards by metal shields
—
taking care not to touch
electronic components.

Wear grounded wrist or foot straps or ESD shoes or heel grounders
to dissipate unwanted static energy.
 Prior to handling boards, dispel any charge in your body or
equipment.
 Ensure components are transported and stored in static safe
packaging.

When returning boards, carefully package in the original carton and
static protective wrapping.

Ensure ALL personnel are educated and trained in ESD Control
Procedures.
In general, exercise accepted and proven precautions normally
observed when handling electrostatic sensitive devices.
A warning label is placed on the packaging, identifying products using
electrostatic sensitive semiconductor devices.
