Chargebuster Overhead Ionizer
Installation, Operation and Maintenance
Description
The Desco Chargebuster Overhead Ionizers are steady
state DC ionizers designed to cover 2 foot by 5 foot (60473)
or 2 foot by 4 foot (60640) for use in ESD sensitive work.
The specially designed 3-speed fan modules create better
coverage, consistent offset voltage (±10 Volts) and superior
discharge times (< 3 seconds) tested per ANSI/ESD STM
3.1. The Chargebuster Overhead Ionizer is equipped with
an Auto-Feedback system that continuously optimizes the
performance and will automatically shut down and alarm
should the supply voltage drop.
“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”. (ANSI/ESD S20.20-
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/ESD S20.20-2007 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 ESD
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 ESD TR20.20 section 5.3.6.7 Maintenance /
Cleaning)
Packaging
1 Chargebuster Overhead Ionizer
1 Hanging Kit
1 Power Cord, North American Plug
3 Emitter Point Cleaners (60473)
2 Emitter Point Cleaners (60640)
1 Certificate of Calibration
Installation
Place the unit at a desired location where that the airflow will
not be restricted. Be sure that the ON/OFF switch located
on the rear of the unit is in the OFF position. Plug the power
cord into the unit and then into the appropriate AC power
source.
Operation
1. Set the fan speed switch to the LOW, MED, or HI
position. Higher airflow will result in faster neutralization
rates.
2. Position the ionizer so that maximum airflow is directed
towards the items or area to be neutralized.
3. Turn the unit ON. When the unit is first turned on, it
conducts a self-test. The audible alarm will sound and
the LED will cycle through the colors red, yellow and
green. The LED will remain green during normal
operation.
