Chargebuster Jr. H/O with Emitter Cassette
Installation, Operation and Maintenance
that have large capacitance, like people and carts; however,
ionizers should be considered as a method for charge
neutralization in cases where grounding cannot be achieved.
Air ionization can neutralize the static charge on insulated
and isolated objects by producing separate charges in
the molecules of the gases of the surrounding air. When
an electrostatic charge is present on objects in the work
environment, it will be neutralized by attracting opposite polarity
charges from the ionized air. Note that ionization systems
should not be used as a primary means of charge control on
conductors or people. (Reference: IEC 61340-5-2:1 paragraph
5.2.9).
The Chargebuster Jr. H/O is available in 2 models:
Figure 1. Desco Chargebuster Jr. H/O (High Output) Ionizer
Description
The Desco Chargebuster Jr. H/O ionizer is a compact
and lightweight auto-balancing bench top ionizer with our
patented* emitter cassette that slides out for easy cleaning and
replacement. The Chargebuster Jr.’s unique active feedback
balancing circuit automatically ensures and maintains the
unit’s ion balance despite variations in line voltage, air speed,
or emitter electrode condition. The unit’s compact, efficient
design minimizes bench top space requirements and need for
maintenance, while maximizing neutralization efficiency and
overall performance.
Ionizers are useful in preventing electrostatic charge
generation, ElectroStatic Discharge, ElectroStatic Attraction,
as well as preventing equipment latch-up and safety related
shock. ANSI/ESD S20.20 Paragraph 6.2.3.1 Protected Areas
Requirement states: “Ionization or other charge mitigating
techniques shall be used at the workstation to neutralize
electrostatic fields on all process essential insulators if
the electrostatic field is considered a threat.” Ionization is
used to neutralize charges on process necessary insulators
and isolated semiconductors. Some examples of process
necessary insulators are: the PC board itself, plastic test
stands, plastic housing where a PCB may be mounted, as
well as computer monitor screens and regular cleaning wipes.
Examples of floating or isolated conductors are: loaded PCB
mounted in a stand where the pins are not contacting the
dissipative workstation. Ionization is not effective on items

All models come equipped with a universal IEC cord connector
and a removable emitter cassette. Models
include a standard IEC cord set. All models are calibrated and
traceable to NIST.
IONIZER SELECTION
ANSI/ESD S20.20 paragraph 6.1.1.2. ESD Control Program
Plan Guidance states: “The Plan should include a listing of the
specific type of ESD protective materials and equipment used
in the Program.” When selecting an ionizer life cycle costs
should be considered including: equipment cost; installation
cost; and operation and maintenance cost.
The unit is normally placed at one end of a workbench or area
to be neutralized. It may also be wall mounted or mounted on a
shelf. The ionizer’s decay time (neutralization efficiency) will be
best from approximately 6” to 42” in front of the unit, and will
drop off as the distance from the unit increases.
