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 immediate—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 their edges, 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 product using electrostatic sensitive
semiconductor devices.
