TECHNICAL BULLETIN TB-6595
IRIS Room Ionization System
Operation and Maintenance Instructions
Electrostatic Attraction is the presence of charged
surfaces that accelerate the deposition of particles of
opposite polarity, accelerating contamination within the
environment. IRIS reduces particle charge and surface
charge. Without mutual attraction, a particle will remain
suspended in the airflow, moving harmlessly by the
process and exiting through the air handler of the clean
room.

Description
The EMIT Intelligent Room Ionization System (IRIS)
neutralizes electrostatic charges in an entire cubic
volume of a room environment. Applications for IRIS
include Electrostatic Discharge (ESD) and Electrostatic
Attraction (ESA).
Electrostatic Discharge is the presence of excess
charge on a surface which can create an electrostatic
field that causes the formation of a spark and damages
microelectronic components. IRIS creates a static
protective environment for ESD sensitive items by
reducing static charges on surfaces. Controlling surface
charge and static contamination is a key component
of optimum product handling procedure in a high yield
environment.
ANSI/ESD S20.20 section 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.” Air ionization can neutralize the static charge
on insulators (which cannot be grounded) and isolated
conductors (which are not grounded) 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 means
of 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: EN
61340-5-2 clause 5.2.9].

Zone Setup
Each IRIS Zone is supported by one IRIS Power
Supply. The power supply can power and control up to
300 overhead mounted emitters covering approximately
5,200 square feet. Standard ABS components and a
modular design allow the emitters to be configured to
fit most pre-existing rooms. Each emitter produces
bi-polar ionization resulting in stable ion production
when in use.
Each IRIS Zone is independently controlled by TEAM5
IRIS Client Software. TEAM5 IRIS Client Software logs
all significant events to a database for ongoing analysis
and for compliance with ISO-9000 and ANSI/ESD
S20.20 requirements.
Total ion concentration is controlled by changing the
voltage levels and length of pulse. Higher voltage and
longer overall pulse duration will produce a greater
number of free air ions. Ion offset voltage balance is
set to an optimal point by controlling the “ON” time ratio
between positive and negative pulses to the emitter
point.

Installation of the ionization system consists of conduit
bars attached to the ceiling of the room with stainless
steel brackets. These brackets attach to standard 2'
x 4" drop ceiling frames with or without HEPA filters.
The brackets and hangers are mounted to allow the
changing of lights and filters with minimal interference.
Zone Monitoring and Feedback
Each IRIS power supply incorporates 3 external sensors
to provide feedback to monitor stability of each zone.
Each sensor is assigned an alarm threshold. The
stability of each zone is controlled by the set duration
of power to each emitter. During the initial calibration
process, the power state is adjusted manually via the
TEAM5 IRIS Client Software while monitoring the work
environment with a Charge Plate Monitor until the
desired conditions are achieved. The duration of each
power state is recorded and saved during calibration.
These values are then used by the client computer to
control the power supply during normal use.
A sensor alarm is triggered if the sensor or power
values deviate from the saved calibration value by more
than the selected alarm range percentage. A “soft
alarm” alerts the system operator of the issue without
turning off the IRIS system. A “hard alarm” alerts the
system operator of the issue and turns off the IRIS
power supply. A tolerance threshold can be set to alarm
whenever the room system’s performance shifts too far
from its calibrated values. Sensors may be disabled
due to unordinary maintenance or activity in clean room.
Maintenance
Periodic maintenance including general cleaning,
emitter pin cleaning and recalibration may be necessary.
All power supplies must be turned off before any
maintenance procedures are taken. The conduits and
housings may be wiped clean using an all purpose
cleaner (make sure that all cleaners used are consistent
with requirements of the controlled environment/
cleanroom and ESD Protected Area). The emitter
points should be cleaned using a swab dampened with
Isopropyl.
TEAM5 IRIS Client Software
The IRIS Power Supply is controlled by a serial
communication line hard wired to the IRIS Tablet PC
with TEAM5 IRIS Client Software. TEAM5 IRIS Client
Software monitors and displays the feedback from each
of the three sensors and the high voltage output from
the power supply. TEAM5 IRIS Client Software is used
to set calibration profiles. A “Factory Default” profile will
be set at the time of the initial install of IRIS. Additional
profiles may be added and saved.

the IRIS Touchscreen Tablet PC
TEAM5 IRIS Server Software
TEAM5 IRIS Server Software allows for each zone
to be monitored remotely. TEAM5 IRIS Client and
TEAM5 IRIS Server communication takes place over
a local area network (LAN). Multi-zone power cycle
synchronization allows multiple zones in the same room/
area to be coordinated for optimal performance.
Design and Installation Quotes
EMIT includes application, engineering and sales

The performance of the EMIT IRIS – Intelligent Room
Ionization System is directly related to uniform airflow
throughout the area being ionized. Minimum laminar
airflow of 70 FPM and distance from emitter to test
surface of 5' is necessary to enable the system to
meet Offset Voltage (Balance) and Voltage Decay
(Discharge Times) performance specifications. In the
event that minimum environment specifications cannot
be met, some system modification may be required. In
addition, some large objects (machines, etc.) may have
a significant effect on the ionization performance in the
vicinity of the objects.
Upon completion of IRIS Installation, IRIS will
be calibrated to the required limits of ANSI/ESD
S20.20-2007 with offset voltage of less than ±150V,
as well as predetermined decay times agreed upon by
both customer and EMIT tested per ESD TR53. Any
changes to the environment of the IRIS installation
Scope of Work after the installation may require
modifications and recalibration. This includes and is not
limited to airflow changes to the environment, layout
changes (including work benches and machinery).
All ionizers require periodic maintenance, emitter pin
cleaning, and recalibration. Associated costs are not
included in the original purchase price. All testing and
recalibration of the IRIS performed after installation will
be quoted to the customer for parts and labor separately
from the initial Quotation and Purchase Order.
