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 non-conductors in the work place is required to ensure that
appropriate actions are implemented, commensurate with risk to ESDS
[ESD sensitive] items”. (ANSI/ESDS20.20-2007 Foreword)

In order to mitigate field-induced CDM [Charged Device Model] damage,
the ESD program shall include a plan for the handling of process-required
insulators. If the field exceeds 2,000 volts/inch, steps shall be taken to
either: A) Separate the insulator from the ESD-sensitive device by a
distance of 30 cm (12 inches); or B) Use ionization or other charge
mitigating techniques to neutralize the charge. (ANSI/ESDS20.20-2007
section 8.3)

The primary method of static charge control is direct connection to ground for
conductors, static dissipative materials, and personnel. A complete static
control program must also deal with isolated conductors that cannot be
grounded, insulating materials (e.g., most common plastics), and moving
personnel who cannot use wrist or heel straps or ESD control flooring and
footwear. Air ionization is not a replacement for grounding methods. It is
one component of a complete static control program. Ionizers are used when
it is not possible to properly ground everything and as backup to other
static control methods. In clean rooms, air ionization may be one of the
few methods of static control available. (ESD Handbook TR20.20
Ionization, section 5.3.6.1)

All ionization devices will require periodic maintenance for proper operation.
Maintenance intervals for ionizers vary widely depending on the type of
ionization equipment and use environment. Critical clean room uses will
generally require more frequent attention. It is important to set-up a routine
schedule for ionizer service. Routine service is typically required to meet
quality audit requirements. (ESD Handbook TR 20.20 section 5.3.6.7
