Facility Engineering Protocols for Compliant Static Control Flooring Installation

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…

The Truth About ESD Class 0

The electronics industry is terribly confused by the term Class 0. Particularly when it comes to electrostatic discharge (ESD) device sensitivity and how the term applies to factory controls designed to mitigate ESD. The confusion manifests itself through the many companies and engineers seeking direction on how to “become qualified to handle Class 0 devices.” They are seeking this information because their equally confused customers have imposed requirements on them to meet this mythical level of performance. Not only is Class 0 as a factory level of performance a contrived ideal, it is not a realistic or useful goal. Our purpose here is to explain reality and what is necessary for understanding device ESD sensitivity and establishing control.
