EMIT Zero Volt Ionizer


America


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)

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)

ozone• RS-485 communication for use with EMIT SIM Software



America


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 sothat 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.

Description

The Overhead Zero Volt Ionizer combines the effectiveness of steady-state 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 (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 (Bench Top and Overhead) Zero Volt Monitor (Dual Operator and Workstation) Zero Volt Monitor Solo (Single Operator and Workstation) Dual Programmable Monitor Ultra Low Voltage Monitor

EMIT SIM uses serial number tracking to manage re-calibration schedules for each device

All monitoring is done via a 2 wire serial RS-485 daisy-chained bus. Total cable length of each loop must be less than 1,200 meters (~4,000 feet).

Supported Operating Systems: Windows XP, Windows Vista, Windows 7(32-bit and 64-bit)

What is EMIT SIM?

EMIT SIM


America


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
