Bench Top Blower Ionizer
Installation, Operation and Maintenance
Description
This ionizing unit is a self-balancing bench top ionizer. The
ionizer’s patented (US Patent 5,008,594) Faraday Balance
System assures low offset voltage or balance automatically.
It offers greater efficiency and easier cleaning than
conventional ionizers. The Bench Top Ionizer is designed
to neutralize static electricity from insulators and isolated
conductors in localized work areas in assembly rooms, wave
solder lines, laboratories, QC, test stations, packing and
shipping areas and clean rooms.
Ionizers are useful in limiting electrostatic charge generation,
ElectroStatic Discharge, and ElectroStatic Attraction, as
well as preventing equipment latch-up. 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.” 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 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).

Ionizer Selection
ANSI/ESD S20.20 section 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
- operation and maintenance cost

Installation
The unit is normally mounted at one end of a workbench or
area to be neutralized. It may also be mounted to a wall or
shelf. The ionizer’s neutralization (discharge) times will be
best from approximately 6" to 42" in front of the unit and will
drop off as the distance from the unit increases.
