What is an EPA?
An EPA is an area that is maintained safe for handling static
sensitive components by keeping electrostatic fields and
voltages to an insignificantly low level. An EPA should have
well defined boundaries so that it is clear where the safe area is
entered and left.
•
All personnel handling sensitive devices are grounded.
•
All non-insulating and conductive objects are grounded, so
that electrostatic charge cannot build up on these.
•
Any surfaces on which ESDS are placed must be
connected to EPA ground. According to practical
experience, we have chosen the overall electrical
performance of the reader in order to match its point-to-
point and point-to-ground resistance in a range safely
between 1 KΩ and 10
hard grounding and electrical insulative conditions.
•
Insulating materials are strong ESD sources and so they
are excluded from the EPA where possible. Where this is
not possible special measures such as ionisers are used
to neutralise electrostatic charges.
The Gryphon™ ESD
The ESD-safe GRYPHON™ reader has been developed and
tested to match strict requirements of EPA controlled areas.
The GRYPHON™ ESD employs third generation low-carbon
polymers, and is an advance beyond currently available ESD-
safe readers.
