Description

The Desco Ionization Test Kit allows the

Static Field Meter to be used to measure the offset

voltage (balance) and charge decay of ionization

equipment. The Test Kit also includes a Charger used to

place a ±1000V charge on the

making it possible to also measure the discharge times

of air ionization equipment per ANSI/ESD SP3.3 Periodic

Verification of Air Ionizers. The

includes the

highly portable and cost effective means of verifying the

performance of a wide variety of ionization equipment.

Note: The

operate only with the

compatible with other brands.

Although not as accurate, the Desco Ionization Test Kit

has been designed to make measurements that

correspond to those made by using a charged plate

analyzer and ANSI/ESD S3.1. The Ionization Test Kit

provides convenience and portability to test per ANSI/

ESD SP3.3 Periodic Verification of Air Ionizers or

Compliance Verification ESD TR53. We recommend

EMIT’s

measurements are required.

The Ionization Test Kit includes a slide-on isolated

Conductive Plate, a ±1000 volt Charger and a durable

thermoplastic carrying case with custom cut-outs for all

of the above components along with the model

Digital Static Field Meter.

Charged insulators in the ESD protected area can

adversely impact quality, productivity, and reliability.

“When any object becomes electrostatically charged,

there is an electrostatic field associated with that charge.

If an ESDS (ESD sensitive) device is placed in that

electrostatic field, a voltage may be induced on the

device. If the device is then momentarily grounded, a

transfer of charge from the device occurs as a CDM

(Charged Device Model) event. If the device is removed

from the region of the electrostatic field and grounded

again, a second CDM event will occur as charge (of

opposite polarity from the first event) is transferred from

the device.” (ESD Handbook ESD TR20.20 section

2.7.5 Field Induced Discharges)

Compliance verification should include periodic checks

with a static field meter to determine if high

charging material is present in the ESD protected area.

All packaging and other materials that may be

electrostatic generative to 2,000 volts must be kept a

minimum of 12" from ESD sensitive items at all times. It

is proper to rub an item and measure that it can charge.

“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

B. Use ionization or other charge mitigating techniques

Other steps that can be taken are to remove the item

from the ESD protected area, periodically coat with a

topical antistat, or replace with a static control protective

version of the item.

by a distance of 30 cm (12 inches); or

to neutralize the charge.” (ANSI/ESDS20.20 section
