Description
Desco Chargebuster® Overhead Ionizers are
steady-state DC ionizers designed for use in ESD
protected areas. The 2-fan ionizers (60640, 60467)
have a 2' x 4' coverage area, and the 3-fan ionizers
(60473, 60468) have a 2' x 5' coverage area. The
Chargebuster® Overhead Ionizers' discharge times
(< 3 seconds at 18") and low offset voltage (±10 volts)
meet the required limits of ANSI/ESD S20.20 < ±35
volts tested per ANSI/ESD STM3.1 and ESD TR53.
Its emitters are made of pure tungsten and spaced
further apart to minimize ion recombination, increase
discharge efficiency and provide a broader coverage
area. The fans have 3 speeds (high, medium, low)
which produce consistent performance at all 3 settings.
The Chargebuster® Overhead Ionizers utilize an
auto-feedback system that continuously optimizes its
performance and automatically alarms and shuts down
should its supply voltage drop.
The Desco 60467 and 60468
Ionizers include 700 lumen light panels (cool white)
that provide additional illumination to the work area and
improve visibility and productivity. The

"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 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 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."
