Antistatic
Antistatic materials, as defined by the EIA and the ESD Association,
refers to the property of a mate- rial that inhibits triboelectric charging.
A material that inhibits the generation of static charges [generally less
than 200 volts] from triboelectric generation is classified as antistatic.
These materials would be arranged in the triboelectric series near cotton,
a electrically neutral material. Materials ordered on ei- ther side of
cotton generate some static charge, but in very small amounts. Note: a
materialís anti-static characteristic does not necessarily correlate with
its resistivity. An antistatic material can be conductive, dissipative,
or even insulative. Only antistatic or dissipative antistatic materials
should be used in ESD safe areas. Only contact with a conductive material
can damage a charged device. |
