EMIT Zero Volt Ionizer
Benefits
The primary functions of ionizers are to:
• Neutralize process necessary insulators that can charge ESDS devices/
assemblies via induction, thus creating potential CDM damage
• Neutralize ESDS devices / assemblies that are not grounded, and
therefore are a floating conductor, thus creating potential CDM damage
• Neutralize insulators where particulate contamination can cause visual
defects (EX – dust on plastic or glass lenses, attracted to / held in place
by electrostatic attraction)

EMIT Benchtop Zero Volt Ionizer
Description
The Zero Volt Benchtop is a compact and lightweight dual
steady state DC auto-balancing benchtop ionizer. The unit is
normally placed at one end of the workbench or area to be
neutralized. It may also be wall used in conjunction with an
ionizer mounting arm to save valuable workspace. The
ionizer's neutralization time will be best approximately 12” to
36” directly in front of the ESDS device. Decay times will
increase as the distance from the unit increases.
Ion Offset Voltage (Balance) feedback sensors
“Ionizers utilized as air ion sources are designed to provide balanced amount of positive and negative
ions. Many of them feature an internal feedback system (with ion sensors usually incorporated into a
grill of the ionizer’s outlet) to sense and correct air ion imbalances.” (ESD Association working group
3 Proceedings of 27th EOS/ESD Symposium)

EMIT Benchtop Zero Volt Ionizer
Operation
Set the fan speed switch on the rear of the unit to the
LOW, MED, or HI position. Higher airflow will result in
faster neutralization rates. Position the unit so
that the maximum airflow is directed at the items or
area to be neutralized. Turn the unit ON.
When the unit is first turned on, it conducts a self-test.
The audible alarm will sound and then the LED will
cycle through RED, YELLOW, and then GREEN. The
LED will remain GREEN during normal operation.

EMIT Overhead Zero Volt Ionizer
Description
The Overhead Zero Volt Ionizer combines the effectiveness of steadystate DC ionization with ease of adjustability, communication capability,
and the flexibility of a microcontroller based design to produce a
versatile and stable ionization system. Available in both two or three
fan. Three fans produce extended ionization coverage, and are ideal
for areas where bench space is limited.

ANSI/ESD S20.20
“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/ESDS20.20-2007 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/ESDS20.20-2007 section 8.3)

EMIT SIM
What is EMIT SIM?
 EMIT SIM (Smart Ionization & Monitoring) is software designed to monitor and record the
activity of EMIT’s line of Smart Products
 This list of products includes:
 Zero Volt Ionizer
 Zero Volt Monitor
 Zero Volt Monitor Solo
 Dual Programmable Monitor
 Ultra Low Voltage Monitor
(Bench Top and Overhead)
(Dual Operator and Workstation)

Why EMIT SIM?
 Unsupervised Reliability
 Ionizers and monitors sometimes have alarms which may go unnoticed by the line of


workers
EMIT SIM will record and display failures to notify supervisors or engineers when a device
needs attention
Eliminates the need to rely on people to physically check the devices every day
 Quickly Identify Failure Types
 All alarms and exceptions are automatically recorded
 Use the logs stored in EMIT SIM to identify any exceptional events that occurred during the
assembly of a failed product
 Manage Calibration and Maintenance Schedules
 Customize your maintenance schedule to automatically display notification when
any one group of devices need calibration or maintenance
“Compliance verification records shall be established and maintained to provide evidence of conformity to
the technical requirements.” (ANSI/ESD S20.20-2007 section 7.3)
