Description
The Desco 50692 Pencil Type Ionizer uses compressed
clean dry air (CDA) to neutralize electrostatic charges
and dislodge dust and debris in tight, compact spaces.
It is an ideal choice when cleaning parts and assemblies
in electronic, medical device, and semiconductor
applications. It is commonly used in applications such
as mobile phone manufacturing, PCB assembly, watch
making, and the cleaning of optics and wafers. Less
than 1 second discharge times with ±15 volt balance
meet the required limits of ANSI/ESD S20.20 and ESD
TR53.
"There is sometimes a need to provide static control
in a small defined area or location. This may be done
to provide static control within production equipment,
in mini-environments, or to facilitate particle removal
from part of a product. Ionizers used for this purpose
may be blow-off guns or nozzles that work with a
supply of compressed air or nitrogen. They may use
either nuclear, soft x-ray or any of the previously
described types of corona ionization technology. It will
be important to choose a method of ionization and
cleanliness of the gas supply that is appropriate to
the work area." (ESD handbook ESD TR20.20 section
5.3.6.5.2.4 Point-Of-Use Ionization)
"Necessary non-conductors in the environment cannot
lose their electrostatic charge by attachment to ground.
Ionization systems provide neutralization of charges on
these necessary non-conductive items (circuit board
materials and some device packages are examples
of necessary non-conductors). Assessment of the
ESD hazard created by electrostatic charges on the
necessary nonconductors in the work place is required
to ensure that appropriate actions are implemented,
commensurate with risk to ESDS [ESD sensitive] items".
