Monitors & Meters: Which One Do You Need?

Monitors and meters may seem like merely a question of semantics. And in most of the world it is, monitors are analogous with meters and vice versa.

But when you’re dealing with electrostatic discharge (ESD) prevention, both have specific purposes and uses that set them apart from one another. And it’s important you know which is which before you start or continue your work with items that can be harmed by ESD.

Monitor: What’s Happening in the Room?

In plain language, in an ESD Prevention situation, the Monitor (noun) keeps known sources of ESD in systematic reviews. It monitors (verb), the ‘progress’ or quality of ESD buildup over a period of time.

So we have monitors for people, that connect to their personal wrist straps, or connect between them and the ESD matting that they are using – in effect, monitoring both.

The key to a good ESD monitor is make sure they provide constant monitoring of the potential ESD in the room. If the monitor fails, a single spark of static electricity can cost hundreds of dollars in damage before it’s quelled.

Meter: Where Is It?

Meters, in an ESD prevention situation, operate more as the means to locate the sources of ESD build up.

Much like the meters used for testing in construction situations, meters will show the relative ESD levels, allowing the user to pinpoint the exact spot where ESD is being generated or not dispersed properly.

This can be on ESD mats, clothing, people and flooring.

Specialty meters can detect and pinpoint ESD specifically in a cleanroom or ionized area.

There are meters that look at a wide variety of potential ESD buildups and smaller units that check select areas only. And meters that check the humidity, temperature, electrical resistance, and any or all of these at once.

There is a secondary subset of meters that you should also be aware of – Testers.

Testers check the grounding of electrical receptacles to ensure they are actually grounded. Imagine the problems and expense of not realizing your electrical plugs were not grounded and subsequently having to discard or repair any sensitive electronics that had been worked on or assembled during the time the ground was inactive.

There are also testers for personal wrist straps and grounding cords.

Are You ESD Aware?

So, the answer to our question above is YES.

It’s not an either/or situation. It’s both. Each tool has its purpose within your ESD control situation, and both are effective in their job – which is generating awareness of ESD.

Are You Grounded: A Look at Cables, Clamps, and Drums

Do you remember the cell phone gas fire scares of the early 2000’s? Because of a couple of erroneously spread Internet rumors, people all across the world became convinced that use of their cell phones while at the gas pump could lead to explosions, injuries, even death!

Despite the fact that the rumors were all proven to be false, several gas station chains, including the one whose safety report was misquoted to create the rumors, posted stickers warning against cell phone use. One Chicago suburb even passed a law banning the use of cell phones at gas stations.

If you look closely, those stickers are still on a majority of gas pumps, at least in the US and Canada. But while there has never been a case where cell phones caused gas fires, the same is NOT true for static electricity.

We’ve talked a lot in the past about the danger even a small electroStatic discharge (ESD) can pose to sensitive electronics. But in a combustible atmosphere, that tiny spark can cause a lot more damage than the cost of replacing a damaged circuit board.

Static is Everywhere

Walking across a room, rustling your clothing, even just the act of raising your arm to scratch your nose can generate a sufficient static buildup to create a subsequent ESD if not dissipated. Under normal conditions, you won’t even notice the buildup until you feel the shock of the discharge being released.

When you’re not working with sensitive electronics, you probably don’t even consider this to be a problem, certainly not in your home or driving in your car. But like all charges, if it’s not given a route to ground, the charge continues to build, increasing the voltage. And if you happen to be in an area with flammable liquids, vapors and even dust, that static charge can cause explosive consequences.

The first step to avoid incidents in any environment conducive to these volatile exposures is to eliminate as many potential ignition sources as possible. But there are often unconsidered, hidden dangers, especially in an industrial setting that can act as accidental ignition switches.

Isolated Conductors = Hidden Dangers

Isolated conductors are conductive objects – metal flanges, fittings or valves in pipework systems, portable drums – which are either inherently or accidentally insulated from being grounded. Because of this, any static charge they generate becomes a potential ignition point.

The best way to avoid this problem is by utilizing bonding and grounding. Bonding is the process of joining two or more objects or containers with electrically conductive wires to neutralize the potential charge between them. Grounding is a more specific form of bonding where an object or container is connected to the ground.

There are a variety of ways to effectively employ bonding and grounding. While OSHA does not give clear directives on how to ground, they do specify when and where grounding as well as bonding procedures should exist.

Getting Grounded

The most obvious example to point to is the common ground, seen in every building – a metal rod is attached to the outside of a building and literally grounded a few inches into the soil. While this method works great for homes, the size of large industrial expanses, such as warehouses or factory floors, means other methods may be more suitable.

For manufacturing or large storage areas, there are a few options. They all involve grounding clamps connected to grounding cables.

If the area has access to the building’s main cold water pipe, a very common semi-permanent solution is to use a bronze pipe clamp as an alternative to the direct building ground. C-Grounding clamps are another popular semi-permanent solution. Of course, always check the reliability of the ground conductivity in these instances.

If you’re like many industrial complexes, though, the isolated conductors are often temporary items, like drums, containers and vessels that come and go as needed. For these instances, you can get a variety of steel- or aluminum-constructed clamps that attach to the container, connecting it through a stainless steel cable to a grounding point, making the drum or vessel safe.

Depending on the environment, you can also effectively ground using the drop valve of a mixing tank or connecting your ground cable to a previously grounded surface – a table or workstation that is already connected to the grounding apparatus.

Whatever method you choose, bonding and grounding are essential for the safety of everyone working in an industrial environment, whether they’re piecing together circuit boards, helicopters… or gas pumps.

What Are the Standards for Electrostatic Protection?

So, you’ve just been tasked with building or designing your first Electrostatic Protection Area (EPA). You’ve started doing your research, but there are so many choices, from so many different companies. Suppliers, manufacturers, third party providers… If only there was some established standard for judging the efficacy and reliability of all those pieces and parts.

Well, you’re in luck! In 2007, the American National Standards Institute (ANSI) in cooperation with ElectroStatic Discharge Association (ESDA) released a unified set of standards for the design, implementation and maintenance of ElectroStatic Discharge control programs.

In the midst of World War I, five engineering organizations recognized the need to develop standards that could eliminate confusion and could be adhered to across all disciplines, without regard to politics, profits or personal preferences. These groups reached out to the U.S. Departments of War, Navy, and Commerce to form an impartial third party non-profit organization, then known as the American Engineering Standards Committee.

Following the war, the organization spent the next 20 years establishing several safety protocols still observed today, like eye protection, hard hat standards and in-house electrical safety while at the same time reaching out to other similarly tasked international organizations.

When the United States entered World War II, the organization, which would eventually come to be known as ANSI, helped to accelerate the war effort and productivity, created more effective quality control measures, as well as helping to advance photography, radio, and even the development of Velcro.

In 1970’s, ANSI established a public review process and began the herculean effort of moving the United States to the metric system. While the general public never really connected with the metric system, the effort did bring ANSI to the forefront of private sector companies who discovered standardization was a way to stay more competitive in an increasingly global economy.

With the advancement of personal computers in the late 70’s and early 80’s, engineers at several companies recognized a need for more understanding of electrostatic discharge and its prevention. They formed the ESD Association, a non-profit, voluntary professional organization that for almost 35 years has sponsored educational programs and developed standards to help eliminate losses due to electrostatic discharges.

Together, leaning on the historical experience of both military and several commercial organizations, ANSI and ESDA developed the definitive standard for ESD protection, the very cleverly named ANSI/ESD S20.20-2007.

Covering about every conceivable area of ElectroStatic Discharge, the ANSI/ESD S20.20-2007 utilizes both the human body model and the machine model to provide a broad set of guidelines for ESD protection.

The Human Body Model is the military standard that defines and rates the vulnerability of an electronic device to the ESD generated by a human being touching it. The Machine Model works similarly, except it rates the vulnerability of a device receiving a machine discharge into ground. It was originally developed by car manufacturers as their plants moved to more mechanized production technology. The Human Body Model is about 10 times more sensitive than the Machine Model.

There is a lot to explore in the ANSI/ESD S20.20-2007 guidelines, but for the purpose of this primer, the document highlights 3 fundamental ESD control principles:

All conductors should be grounded. This includes the personnel and the surfaces they are working on. We recommend, at a minimum, personal grounding wrist straps, ESD table or bench mats, and a common ground cord.
Necessary non-conductors – certain circuit board materials, device packaging, etc. – cannot lose their electrostatic charge by being grounded and appropriate precautions must be implemented.
Static protective materials, such as ESD shielding bags or ESD totes and boxes must be utilized when transporting sensitive electronics outside a properly prepared EPA.

There are slightly less stringent standards that apply to floors and bench mats, but ANSI/ESD S20.20-2007 is the highest and most comprehensive guideline so far. So when you’re shopping for the parts needed to establish your EPA area, always look for companies that maintain that standard in their products and services.

Conductive vs. Dissipative Materials

In the mid-1820’s, Georg Ohm, a self-taught mathematician and physicist, began doing experiments in the newly discovered field of electromagnetism. Hoping to advance his stalled career, he used the work of Hans Christian Ørsted as a jumping off point, discovering an inverse mathematical relationship between current and resistance.

Georg Simon Ohm

Unfortunately, in an effort to make his theories more understandable to non-mathematicians, he managed to alienate the scientific community and his groundbreaking work went unrecognized for almost 15 years.

Today, he’s remembered by the law that bears his name and its legacy, the standardized unit by which we measure electrical resistance – the Ohm (Ω).

Electrical Resistance: The Water in Pipe Analogy

To put it simply, what Ohm had discovered, but failed to adequately communicate, is that electricity acts like water in a pipe. In this analogy, resistance tells us how wide or narrow the “pipe” transmitting the electricity is.

When two items touch each other, they create an electrostatic charge – one item is positively charged, and one negatively charged. When the items are separated, it creates a triboelectric effect – a buildup of potential energy which can result in an electrostatic discharge (ESD).

In our quest to prevent ESD, which can be damaging and potentially catastrophic to sensitive electronics and circuitry, there are several approaches that vary, depending on the situation.

To illustrate those, we go back to Ohm’s electrical “pipe.”

At the narrowest end of the pipe, we have insulative materials – wood, carpeting, plexiglass. Insulative materials prevent or severely limit the flow of electrons across their surface.

While it may seem that this is the highest and best protection, the opposite is actually true. Because insulative materials are self-contained, they do not ground – meaning the potential energy continues to build up without going anywhere, until it comes into contact with another object, at which point, the new item is bombarded with the electrostatic discharge.

At the widest end of the pipe, we find the conductive materials – copper, steel, water. Conductive materials offer almost no resistance to electrostatic discharge. The electrical charge moves quickly through the materials – too quickly, which can lead to significant problems, as well as safety hazards.

In between these two extremes are the two materials most often used for ESD storage containers, matting and flooring: static conductive and static dissipative.

Towards the wider end of our metaphorical pipe, we find static conductive materials. Because of the low electrical resistance, electrons flow easily across the surface, and can be grounded safely. Typically, static conductive materials are most often used for ESD flooring.

Towards the narrower end of the pipe we find static dissipative materials. The higher resistance of these materials keeps the electrical charge more under control as it slowly flows over the surface and into a ground. Static dissipative materials are much more commonly used for ESD prevention and can be found in table top mats, ESD shoes and some flooring.

For storage containers – boxes, bins & totes – both conductive and dissipative materials can be used, depending on individual needs. Just keep in mind that dissipative materials have a higher resistance than conductive materials.

10 Common Terms in ESD & What They Mean

In 1865, Lewis Carrol published Alice’s Adventures in Wonderland, at the time, a thinly veiled political commentary wrapped in a fictional form.

Who knew that 150 years later, the book would have spawned several movies, pop cultural references, and a Grace Slick song.

But the most enduring artifact of the novel in today’s world – possibly reinforced by its own self-reference in the Matrix films, is the term “Rabbit hole.” In Alice’s universe, it meant falling into a world of confusion. Today it means losing track of time as you plumb the depths of a topic.

In our effort to be a provider of full service ESD solutions, we give you… The ESD rabbit hole – 10 Common Terms in ESD and What They Mean…

10 Common ESD Terms

The obvious place to start is with the term itself: ESD

ESD stands for ElectroStatic Discharge, a specific type of Electrical Overstress (EOS), defined as the sudden flow of electricity between two electrically charged objects caused by an electrical short, insulation failure, or simple contact. This is most often observed as static electric shock.

Electrical Overstress (EOS) is the exposure of an item to a current or voltage beyond what it can handle. When we’re talking ESD, it’s not just a static shock – because of the nature of sensitive electronics, even just a tiny bit of energy generated by lifting your hand or sliding across a desk can be dangerous enough to damage a component while you’re working, which is shy we recommend common grounding.

Common Grounding is a grounded device where two or more conductors are bonded, or a system for connecting two or more grounding conductors to the same electrical potential. Think of it as a lightning rod for your workstation.

Triboelectric Charging is the generation of electrostatic charges when two materials make contact, or often are rubbed together, then separated. This is what most people call static cling. The polarity and strength of the charges produced differ according to the properties of the materials.

Surface Resistance is measured in Ohms, and tells you how easily an electrical charge can travel across a type of surface. It might be helpful to think in terms of a water pipe analogy. The higher the resistance, the narrower the pipe. In the ESD world, a surface is either conductive or dissipative.

Conductive – A surface is conductive when it has a low resistance, anywhere from no resistance at all, such as water or copper, to mid-level resistance. This would be the wider of the two water pipes.

Static Dissipative – A surface is dissipative when it has a higher resistance, anywhere from the top end of the conductive to so much resistance that only a tiny trickle of “water” comes through the pipe.

Degradation is static electricity damage that weakens an electronic device, while giving the appearance of operating within normal parameters. However, once degraded, a device may fail catastrophically at a later point or just not last as long as it should.

Catastrophic failure is static electricity damage to a device that causes it to cease to function. The device must be replaced.

Ionization is the process by which a neutral atom or molecule acquires either a positive or a negative charge.

To Neutralize is to eliminate an electrostatic field by recombining positive and negative charges, either by conducting the charge to ground or by introducing an equal opposite charge. The charges cancel each other out, leaving a zero charge on the item.

The Truth About 11 Myths of Electrostatic Discharge

Would it surprise you to know that a good portion of our modern world would be unable to function without the help of electrostatic discharges (ESD’s)?

No one seems to know quite how it happened, but in 1984, Scott M. Kunen applied for a patent for a “touch controlled switch” – a device he had developed to allow lamps to be turned on or off with the touch of a human hand.

Little did he know that less than a decade later, computer companies would begin adapting his technology, covering it with a variety of static controlling sheaths, creating the capacitive-touch screen, the basis for all modern smart phones, tablets and touch screen laptops.

So, here’s the truth about the myths of electrostatic discharge.

Myths About Electrostatic Discharge

Myth #1 – All ESD is bad.

The truth is, most people use ESD everyday to make phone calls, send text messages, and create emails. The touch controlled switch and the capacitive-touch screen both operate by transmitting small ESD charges from your body into the devices to signal turning a light on, or the letters or numbers desired.

Myth #2 – Electrostatic Discharge is a modern day problem.

Believe it or not, ESD and necessary precautions to prevent it are older than the United States. In the 1400’s, forts and places that stored or produced explosives, gun powder, and even sawdust could fall prey to horrible accidents, so early forms of ESD control were developed and implemented.

Except, of course, when the good guys needed to blow up the bad guys’ stash in a Hollywood movie.

Myth #3 – ESD problems are really quite rare.

In truth, because of the extremely low levels of ESD required to damage small electronics and the fact that damage isn’t always visible or catastrophic, we may never know just how prevalent ESD events are.

Visible static sparks generated by our bodies have to build up between 500-1000 volts, and it takes twice that charge to be felt. Most sensitive electronics can be damaged by 100 volts or less.

And even if the device continues to function as expected, its life expectancy may be severely diminished and in some cases, latent failure can occur, causing even more damage.

Since we cannot fully prevent or even detect an ESD event, all precautions should be taken to avoid an accidental discharge.

Myth #4 – Discharging fingers and tools before using them is sufficient precaution against ESD mishaps.

Unless you are able to hold your body AND tool perfectly still, you can (and often do) build up a replacement charge that can be discharged into your electronics.

As mentioned above, because of the negligible amount of charge necessary to potentially damage the sensitive parts, you have no way of knowing you are not transmitting a dangerous ESD. It’s better to be safe than sorry.

We recommend that you always use personal wrist straps, dissipative mats and grounding cords for the best chance of circumventing ESD problems.

Myth #5 – You have to touch an item to transmit an ESD to it.

As mentioned above, it takes very little for the human body to build up an electrostatic discharge. Just the movement of lifting your foot off the ground can generate up to 1,500 volts.

And that generated charge can easily leap from your hand to your unprotected device inches away.

Stay tuned next week for Part 2 of The Truth About 11 Myths of Electrostatic Discharge…

Faraday Cages? The Surprising Facts

Faraday Cages

After 10 years, the science fiction show The X-Files recently returned to television. In the very first new episode, there is a scene where scientists are studying apparent alien technology, all the while protected from potential harm because the technology is housed in a Faraday cage.

For most people, Faraday cages seem like the stuff of science fiction – boxes built to protect folks with overactive imaginations who fear the world will end with a sudden electromagnetic pulse or EMP. But what if I told you that most people benefit from at least one Faraday cage almost every day?

The first Faraday cage was built back in the 1830’s, by Michael Faraday, hence the name. Faraday was an experimental physicist who worked primarily studying electromagnetism and electrochemistry.

Rumor has it that Albert Einstein had a photo of Faraday that he kept on the wall of his study, right next to his picture of Isaac Newton.

One day Faraday noted that during one of his experiments, excess energy from a charged conductor only rested on the exterior of a container, for some reason not penetrating through the container to ground as electricity typically does.

He set about constructing a box to prove his theory that the inside was somehow shielded from the electrical charge.

He built a room, entirely lined with metal foil and subjected it to high powered electrostatic discharges, simulating lightning. But the interior of the room showed no gain in electricity.

The shielding had forced the negative charges to the outside and the positive charges to the inside, essentially canceling out the electrical current before it could affect anything within the room.

Later, he added a grounding rod and verified that the charge canceled itself out as it traveled around and into the ground.

Today, the principles that Faraday discovered almost 200 years ago are used all across the world to protect people from stray electromagnetic charges. Ever wonder why your cell phone drops calls when you’re in an elevator? It’s a semi-enclosed Faraday cage.

The MRI room in medical facilities, USB cables, coaxial cables (the ones you used to get cable TV from), even cars and airplanes use Faraday shielding to help protect their precious cargo.

And if you want to see one up close and personal, take a look at your microwave. The metal lines in the glass complete the Faraday cage that protects us from electrical discharge and the radiation used to cook your food.

On a smaller scale, metalized static shielding bags protect small electronic components and circuit boards from the much smaller personal EMP’s our bodies generate, which could cause serious damage to these components. Properly sealed ESD boxes and totes, as well as conductive bins use the same principles to protect larger or larger quantities of components.

Of course, while Faraday cages can be ungrounded and even nested to enhance protection, we always recommend taking the proper grounding procedures to protect yourself and your circuitry.

So remember, Faraday cages are not just for “Doomsday Preppers” and science fiction story tropes. They are at work every day to make our world a safer place.

ESD: Grounding, Isolation & Prevention

The Pilllars of ESD Protection

We’ve all had it happen. We’re opening our car door on a cold day, or we’ve just shuffled in our socks to the door and the moment we reach out, pop! A small snap of static electricity reminds us that we’re alive.

Think back to when you were a kid – your dad or uncle perhaps, showed you the power of static electricity by rubbing a balloon on your head and sticking it to the wall or causing your hair to rise up of its own accord. These tricks with static electricity are great for a chuckle or two. When you’re rubbing the balloon or your socks on the floor, it creates an imbalance of electrons, and that potential energy rests on your body or the surface of the balloon, waiting to discharge. Eventually it does and this sudden restoring of the electrons to their neutral state is called an electrostatic discharge or ESD.

That little tiny jolt of static electricity seems small but is really 3,000 volts – for humans, it’s the amperage that gets you. Unfortunately, for small electronics: circuit boards, semiconductors or even simple devices around the home, much smaller static discharges – ones too light to ever be sensed by our skin – can cause minor errors, or even completely destroy a device’s usefulness. In this situation, ESD is no laughing matter.

In a business—especially one that manufactures or handles a lot of electronics, but even in a typical office environment—this kind of damage can get expensive quickly.

So today, we’re going to talk about the three pillars of controlling ESD: Grounding, Isolation and Prevention.

Grounding

If you’ve worked with small electronics much at all, you’re probably aware that there are certain things you should do to prevent damage to that circuitry. You’re probably familiar with the third prong on many electrical cords. Just like the grounding plug diminishes the risk of you being electrocuted, grounding yourself and your work area keeps your circuit boards and electrical components safe by discharging any built up static electricity.

At a bare minimum, utilizing a grounding wrist band is extremely helpful. Many sellers include disposable bands when they ship electronic components, but we highly recommend owning and utilizing your own personal metal ground wrist strap that connects directly to your work surface with a personal ground cord. Always make sure the wrist strap is snug and is touching the skin to allow the charge to dissipate.

Isolation

Static charges cannot penetrate containers that are made of conductive materials or have a conductive layer. That’s why electronic components usually arrive in metallized shielding bags or a conductive tote box. Don’t forget you must ground them before opening. And don’t set these components just anywhere. What many people fail to realize is that simple items that can be found on any normal work surface – even an ESD mat – can also cause unnecessary static buildup that could lead to a fatal discharge.

Transparent tape, plastic sandwich bags, water bottles, Styrofoam coffee cups, even paperwork or blueprints can hold a static charge just waiting to wreak havoc on unsuspecting components. And even if you are properly grounded, holding the components too close to your clothing can also result in an ESD.

Prevention

Always take proper precautions when working on electronic components. Follow all of the tips above, and if you’re going to be working on several components or multiple projects, we recommend investing in some ESD bench and table matting for your work surface. It integrates well with a personal ground cord and wrist band and is the best solution for ESD prevention. A few dollars spent here as well as on ESD protective containers can mean plenty of money saved on ruined components as well as lost time while waiting for replacements.

Following these simple suggestions can mean a much safer environment for both you and your electronic components – and you can leave the static charge at home for parlor tricks.

What is the Triboelectric Effect?

Static electricity is an imbalance of electrical charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge.

Nature likes things to be in balance, therefore static electricity will inevitably result in an electrical discharge unless otherwise redirected by means of a pathway or current.

So the question is… How does an imbalance of electrical charges occur?

The answer is with the Triboelectric Effect.

To understand it, we first need to review a few basics.

Where Electrical Charges Come From

At rest, objects are neither negatively nor positively charged. In this state, they are considered neutral with respect to electrical charge.

The basics of the atom: nucleus and electrons

The atom is made up of a nucleus (containing protons, neutrons) surrounded by an orbiting cloud of electrons

If you remember your high-school physics on the construction of the atom, you’ll recall that every atom has protons (which are positively charged) and neutrons (which are neither positively nor negatively charged) in the nucleus, which is surrounded by electrons (which are negatively charged).

The atom holds onto its nucleus very tightly—in fact the forces that hold the nucleus together are, quite literally, nuclear.

The electrons, on the other hand, have the ability to flow from one object to another by contact. Some objects are more willing to release electrons than others, while other objects are more able to attract electrons. Whether electrons are likely to come or go really depends upon the materials, the pairing of two objects and other environmental conditions, such as air quality.

Materials have been ranked by scientists in the order of their ability to hold or give up electrons upon contact. This ranking is called the Triboelectric Series.

The Triboelectric Effect

Under ideal conditions, if two materials are rubbed together, the one higher on the list should give up electrons and become positively charged.

With repeated contact, a bond is created between the objects as the two items exchange electrons. However, when separation occurs, each object does not necessarily carry off the same number of electrons that it brought to the party.

Therein lies the imbalance of electrical charges where one object will have a buildup of negative charges and the other a buildup of positive charges.

This process of building up an electrical charge through contact is known as the Triboelectric Effect.

How Does Electrostatic Discharge Occur?

You have heard that opposites attract. So it is with the negatively charged and positively charged objects.

Remember we said earlier that nature will seek out a balance? Therefore, when you move a more positively charged item close to an item that is neutral or more negatively charged, the electrons will be attracted to—and try to flow toward—the positive charge. The same is true in reverse.

This movement of the electrons seeking balance is the electrostatic discharge, which creates a shock or spark—sometimes too small to detect, and other times quite powerful and destructive!

It is very important to be aware and understand the movement of these electrons through a work space in order to limit the possibility of costly and damaging discharges of static electricity.

Why Should I Care About ESD?

Electrocstatic discharge (ESD)… what in the world is it and why should I care about it?

If you’re an engineer, an architect, or in the electronics manufacturing industry, you’re most likely aware of what ESD is and the havoc it can wreak.

But, if you’re not in any of those industries, should you even bother caring about what it is?

Yes!

Maybe you:

install and maintain computer networks
repair electronic devices
are a serious gamer who likes to tinker with your computers
are a workbench enthusiast who likes to take stuff apart, or
manage a team of people who work with sensitive or valuable data (your data is valuable, right?)

No matter what the case… you need to be aware of electrostatic discharge and its effects on your electronics.

First of all… What is ESD?

Electrostatic discharge, or ESD, is a natural phenomenon. It’s present in everyday life and happens all the time, often without anyone realizing it. It is the sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown (electrical breakdown).

This sudden flow of electricity is what causes problems for computer networks and everyday electronic devices.

An obvious form of electrostatic discharge would be lightning (also known as large-scale ESD event), but a less obvious form would be the shock you feel after walking across carpet and then touching the doorknob. Perhaps the most insidious forms are the ones too small for you to detect, but powerful enough to damage the circuits on your devices.

Why Should I Care?

Two significant reasons for being aware of ESD and its effects are…

Loss of Peak Performance. If you would like your networks or equipment to perform optimally, you should take steps to avoid ESD damage. Over time, ESD reduces the performance of your system and can significantly reduce the life of your equipment. Save yourself the time, money, and hassle and protect your equipment.
It’s Expensive! Over 50% of hardware failures are due to electrostatic discharge. Eliminate ESD and save money!

How Do I Protect My Networks and Devices?

So whether you’re the “IT guy” or the “gamer gal,” creating an Electrostatic Discharge Protected Area is a great starting point, including:

ESD flooring
Grounding devices like wrist straps
Grounded static dissipative work surfaces
ESD clothing and shoes
ESD packaging
Signage
