A Proposed Test Methodology for Evaluating the Electrostatic Characteristics of Floor Materials

February 27th, 2015 No comments

Because the movement of people and materials through sensitive electronics environments generate static charges, the selection and use of floor materials to control electrostatic discharge becomes a critical issue. Frequently, however, users of
these materials base their evaluation, comparison, and subsequent selection on a potpourri of electrostatic properties and test procedures, many of them either inappropriate or inadequate. Facing the same ill-define requirements,
material vendors are at a loss to provide adequate products information for decision making and have little guidance for developing and offering products to meet use requirements. Read more…

The PCS-715A Static Locator does not zero properly

February 3rd, 2015 No comments

Why does your PCS-71A or ESL-715A Static Locator Recently not zero? Even after connecting your meter to earth ground and turn on the meter and hit the “ZERO” button twice, it reads 0.02 instead 0.00.

Agreement between SH&A and the ESD Association for the Level 1 Plant Auditor Program

January 21st, 2015 No comments

Stephen Halperin & Associates, Ltd. (SH&A) an independent consultancy of Bensenville, IL is pleased to announce a new cooperative certification agreement with the ESD Association, Inc. (ESDA) a not for profit association based in Rome, NY. In the agreement the ESDA grants SH&A the authorization to certify candidates to the ESDA’s TR53 Technician designation should they successfully pass SH&A’s Level 1: ANSI/ESD S20.20 Plant Auditor examination. Both organizations focus on the education, training and certification of plant auditors and technicians who must measure and maintain electrostatic discharge (ESD) controls in static sensitive environments. Many of these operations handle highly static sensitive electronic parts and assemblies. Personnel trained and certified in these specialized measurement techniques insure that ESD controls are in-place and functioning to prevent billions of dollars of ESD losses.     Read more…

Facility Engineering Protocols for Compliant Static Control Flooring Installation

Note: This is an article that appeared in the FAcilities Engineering Journal in the July/August 2014 Edition. You can visit the journal’s website at http://www.afe.org

A person walking across an insulative tile floor can build-up static electricity resulting in electrostatic discharges (ESD). When a hand touches a doorknob, it can take 3000 to 3500 volts to feel a sudden shock. In 1971, Intel’s 4004 microprocessor equaled about 2300 transistors. At the end of 2008, Intel’s Dual Core Itanium 2 smashed the 2 billion transistor equivalency barrier.

The Silent Killer: Suspect/Counterfeit Items and Packaging

September 23rd, 2014 No comments

Over the past several years, U.S. based organizations have curtailed traditional internal verification efforts due to reliance on contract manufacturers, distributors and suppliers to do the right thing. The inspection of ESD sensitive parts is very important, but without special safeguards, the additional handling to remove and repack a product for validation can cause both physical and ESD damage in the process. For parts, including those not sensitive to static electricity, measures must be utilized to detect, inspect and validate the packaging that identifies and protects the product.

The Case for using Dew Point for Testing ESD Control Materials

June 17th, 2014 No comments

All ESD Association (ESDA) standards that are used to evaluate the properties of ESD controlled materials require testing under defined temperature and relative humidity conditions. Although the exact values vary by standards document the typical environmental conditions are:

• Low Relative Humidity – 12% ± 3% RH and 230 C ± 30C

• Moderate Relative Humidity – 50% ± 5% and 230 C ± 30C

ESD Control Materials and Electrical Safety Hazards

June 17th, 2014 No comments

For many years companies, that handle electrostatic discharge (ESD) sensitive products, have asked if it is safe to connect their employees to ground when they are working with powered equipment.

The answer to this question is not a simple “yes” or “no”. The grounding methods required by ESD Control Programs such as ANSI/ESD S20.20 and IEC 61340-5-1 often conflict with the requirements for protecting personnel from hazardous electrical currents in some operations. Read more…

Is ESD Walking Test mandatory to have for an EPA?

Recently, a customer asked a question regarding use of the ANSI/ESD STM97.2 Walking Test (Floor Materials and Footwear – Voltage Measurement in Combination with a Person). She wanted to know if it was necessary to have for an EPA (ESD Protected Area). In my opinion the STM97.2 walking test should be used as necessary as follows. Read more…

Using a USB Serial Adapter to connect your PRS-801 Resistance Meter for Windows Vista, Win7 and Win8

April 18th, 2014 No comments

Applies To: Windows® Vista

The Prostat PRS-801 Resistance System comes with an application for your computer where you can transfer data stored on your resistance meter to an Excel® Spreadsheet. However, the PRS-801 Meter itself is only equipped with a RS-232 Serial Port. And because most computers do not have serial ports installed from the manufacturer, you need to use a USB Serial Adapter to connect your PRS-801 to your computer. Read more…
