  • ESD and Static Control Guide

    ESD_StaticWhen working with a printed circuit board, it is important to be aware of electrostatic discharge (ESD). ESD is a common problem that occurs more often than most people realize. When it becomes a serious issue, it can cause major damage to any project. The amount of damage that ESD causes can be catastrophic and force you to replace expensive equipment or scrap the job completely. It is crucial to understand, monitor, and control ESD especially when dealing with electrical devices such as circuit boards and sensors.

     

     

    What is ESD?

    ESD occurs when there is a sudden change of electrical pulses between carriers of static electricity. These exchanges can occur between objects, people, and electrical devices. Some common ways people become statically charged is by walking across a carpeted area, sitting in a chair made of urethane foam, or picking up a poly bag from a bench.


     

    Types of ESD Symbols

    1) ESD Safe – Hand, triangle, and circle.

    2) ESD Sensitive – Hand and triangle

    esd_symbol_l

     

     

     

     


     

    What Causes an Increase in ESD?

    Whenever there is an assembly of several people working in a particular area around sensitive electronics, there is a possibility for high voltages accumulating on workers’ bodies. In addition, conditions where there is low humidity can cause an increase in ESD. The type of floor used can also contribute to a high exchange of electrostatic discharge.


     

    Ways to Prevent ESD

    It is important to create a work area that is free from ESD. One of the first things you should consider when setting up any workstation is to ensure that it is not set up in a carpeted area. Since carpet is a conductor for generating electrical flow, it is important to only use concrete or tile floors to get the best protection.

    Choosing the right equipment is also essential for ESD prevention. There are a variety of products on the market you can choose from including protective wrist straps and other gear to ensure a static free workplace.

    Ways to Monitor ESD in an electronic assembly process

    Once you have a system in place that eliminates potential for ESD, then monitoring your work environment is also important. ESD monitoring can be done through outsourcing or on-site testing using an in-house static testing device such as the Desco 19325 Full Time Continous Single Station Monitor. This type of equipment comes with advanced, innovative features that provide full-time ESD monitoring to prevent accidental occurrences and maintain a safer work environment.  In addition you can monitor ESD events with the 3M CTM082 ESD Pro Event Detector.  The CTM082 detects and counts the discharges as well as shows the relative strength of each ESD event.

    To prevent catastrophic loss and create a safer work environment, it is important to understand, monitor, and control ESD. Ensuring that all employees take part in helping to control ESD is also essential for a prevention plan. By using the right tools and providing education, ESD can be controlled safely.

  • Prevent ESD Damage to Sensitive Electronic Devices

    What is ESD?ESD_Static

    Electrostatic discharge (ESD) is a stream of electricity that occurs suddenly between electrically charged items through contact, electrical breakdown, or an electrical short. There are several reasons that this situation can occur, but the most common is a power outage and subsequent power surge caused by an electrical storm. When static electricity builds up, the ESD can damage sensitive electronic devices, burn out electrical pathways and even cause fires and explosions if a spark is formed near flammable substances.

    Manufacturers of electronic devices advise protecting them against ESD to avoid failure or permanent damage to circuit boards from the higher voltages. Most electronic devices are built with some ESD protection from day-to-day usage, however to protect devices at your home or office during more intense situations further steps should be taken.

    ESD Symbols

    There are three primary symbols to denote ESD awareness as defined in ANSI/ESD S8.1:

    esd_symbol_l- Black triangle with hand and slash through it is often posted with a yellow background, this symbol denotes that a device is susceptible to ESD, and needs to be packaged accordingly. These devices should also be protected once placed in your home or office.

    esd_symbol_star_l- Black triangle with hand and arc around it--This version of the symbol denotes products that are made to protect sensitive devices from electrostatic discharge. These protective items include package, clothing and equipment.

    Desco_ESD_Common_Point_Ground_Yellow- Bold circle with two bold concentric circles and the words ESD COMMON POINT GROUND inside--This symbol designates an ESD ground point where a plug or connector can be attached. This symbol is recommended to be colored black or white on green.

    Protect and Monitor

    If you are working with electronic devices, it is a best practice to set up an Electrostatic Protective Area (EPA). In an EPA, all electrical devices are grounded, higher charging materials are kept out altogether and preventative measures such as anti-static mats are used.

    static shielding bagIf you want to protect your computer, network hardware and other devices from ESD in your home or office, start by keeping the device in its anti-static packaging until you are ready to install it. If you need to transport an ESD sensitive devices, place them in ESD static shielding bags. Place anti-static mats in the area where the devices are stored. Additionally, added surge-protection devices help in keep power surges from sensitive electronics. In the midst of an electrical storm, turning off equipment and disconnecting power cords is additional help.

    Depending on your need, there are several types of monitors to detect levels of ESD from human contact and from contact with charged objects. Measurements can also be taken to determine how much ESD a device can withstand.ctm082

  • 7 Critical Steps to Protect Your Electronics from ESD Damage

    ESD Static ControlESD or Electrostatic Discharge is described as the sudden exchange of electrical pulses between two objects. People, objects and electrical devices are carriers of static electricity. Walking across a carpeted area, picking up a poly bag from a bench or sitting in a urethane foam chair causes an electrical connection between the object and the person. This is also true of objects and electrical devices.

    Most major companies are not aware of the type of damage ESD can cause. Electrostatic Discharge is the “invisible” enemy that robs products of their quality, reliability and functionality. ESD can go unnoticed for months or even years, causing the company to replace sensitive and vital parts, such as circuit boards and sensors.

    7361017 Critical Steps Companies for Protecting Electronics and Operators from ESD

     1) Install or create a static free workplace. Create an area that is safe from electrostatic build up. This includes setting up workstations in non carpeted areas. Carpets are a conductor for electrical flow to generate. Tiled or concrete floors offer the best protection against electrical surges and static build up.

     2) Consider using an air ionizer if non static areas are not possible or available. Provide continuously maintenance to ions to ensure they are providing extra layers of protection by neutralizing the accumulation of electrostatic buildup.

     3) Provide education and training to personnel who work in close proximately with electrical devices and components.  In addition, Before operators are allowed to enter their work area, provide them with protective hand gear, such a wrist straps or antistatic top.

    4) Perform an audit of all equipment. When packing or storing Electrostatic devices, be sure to place equipment and components in static free protective bags and containers to prevent damage.

    5) When setting up new electrical equipment, be sure the devices are grounded properly. Use the proper wall outlets, surge protectors and wiring specifications to prevent electrical shock, and electrical discharge.

    6) When setting up work stations do not use desks, tables or other furniture that contain electrical conducive materials such as stainless stain, aluminum, or foil.

    746_17) Setup an In house Static Testing Center.  Prevention is cheaper than intervention on all levels. Onsite testing is less costly than outsourcing. Encourage workers to test their clothing, shoes and wrist straps before entering the work area. This will ensure that the workers will not discharge electrostatic waves, while they are working with sensitive devices.ThinkingEngineer

  • PCBs and ESD: How to construct a work area that prevents Electrostactic Discharge

    esd_symbol_lElectricity follows the path of least resistance, which is the epitome of why ESDs occur. A short between two charged units creates a weaker path that electricity will take advantage of every time. An example is a lightening strike. Static electricity is attracted to us. Simply walking across a floor can cause a static buildup or even an ESD event. Electrical components are fragile and even a small ESD can cause severe damage. Work area construction practices play a part in preventing ESD from occurring, and those practices begin with prevention.

    Work Station Tools that help prevent ESD

    How the work station is constructed is half of the battle when it comes to preventing ESD. That process is not always within our control. The good news is that there are ways to compensate for construction deficits.

    - Work areas should include a humidity control unit. Humidity plays a large role in electricity build up. There are plenty of aftermarket humidity control units and humidifiers available.  GoKimco does not offer specific models, but if you need help in finding one call us at (800) 521-9197 or email us.

    - Flooring surfaces should be covered with non-conducting flooring finish in work areas and ESD Safe Anti-fatique mats at the workbench or the area designated as the work location or bench. These mats will dissipate static build up before a ESD event occurs.

    - Work surfaces should also be covered using either an anti-static mat or a bench mat with a grounding cord. Both help to prevent static electricity build up that can occur was clothing rubs together.

    Grounding straps for personnel are also essential. Grounding heel straps or wrist straps work well to eliminate static build up that naturally occurs on people.

    • ESD_Static

    The human body is a magnet for static electricity. Using preventative products to reduce static build up is an easy and cost effective way to avoid ESD events. Most of these products are not expensive. Most are easy to install. All of them do a good job of preventing EDS.  Visit our website for a full list of ESD Control products available from GoKimco.

  • Why Worry About Electrostatic Discharge ( ESD ) when working on a Printed Circuit Board?

    static-container-labelFor some, the prevention of Electrostatic Discharge, or ESD, is simply an item on a checklist that you mark through when doing a job, just to keep the boss off your back. However, ESD is a serious issue and can cause catastrophic damage to a project. If you are unconvinced about the ramifications of ESD, read on.

    What Is ESD?

    Electrostatic Discharge is a sudden, unexpected flow of electrical currents between two points. ESD can cause a short, damage to electrical components, and even damage to you and other members of your team. ESD can cause a catastrophic problem on a project, causing you to replace expensive components or even scrap the job and start all over. In addition to the monetary expense that can occur, there is also a measure of stress and even personal ramifications when ESD halts a project.

    How You Can Prevent ESD

    There are several steps you can take to prevent ESD.

      • First, don't let yourself become complacent. ESD is a serious concern and should be treated as such.
      • Next, take the proper steps to prevent ESD. These steps are different for each job, but proper grounding of your work area, your body and project components is imperative.
      • Cool, dry areas are also a concern, so be especially cautious when working in these places.
      • Do not stand on carpeted surfaces, and keep your work components off of fabric, carpet and similar surfaces.
      • Wearing sturdy shoes with a rubber sole with ESD foot or heel grounders can also help prevent ESD. You should also remain aware of your surroundings; there are two symbols that you can look for to assist you.
      • The use of ESD SAFE equipment will help you ensure that you avoid ESD issues when working on a project.
      • You should also keep an eye out for ESD Sensitive labels; these labels indicate that an item is highly susceptible to ESD, so you should exercise extreme caution.
      • Make sure to store circuit boards in an ESD safe container or a static shielding bag.
      • In addition to the precautions taken above, it is recommended that the controls are setup to maintain and monitor you ESD Safe working environment.  A few tips for doing this is to setup ESD monitoring devices and ionizers that will maintain safe areas.

  • 15 Surprising ESD Static Electricity Facts

    esd_symbol_lAlthough many people have heard or know about electrostatic discharge (ESD), there are still many facts about it that may surprise them. The reasons for this can include the many ESD myths/misconceptions still hanging around; another is the fact that ESD is a much more common effect than most people realize.

     

    Some of those rather interesting (if not bizarre) facts about ESD include:

     

    1. High humidity environments increase the chances for ESD trouble/activity.

     

    1. Engaging in simple everyday acts can be considered “risky behavior” in the world of ESD susceptibility. Some of those acts (and the charges they can produce) include:

     

    1. Walking across a carpet (1,500V to 35,000V)
    2. Walking across a vinyl floor (250V to 12,000V)
    3. Utilizing vinyl envelopes (600V to 7,000V)
    4. Working on a polyurethane chair (1500V to 18,000V)

    1. All electronic components/parts have different relative sensitivities to ESD—why they cannot all be treated the same. Some electronic components (and their electronic susceptibilities) to watch out for include:

     

    1. CMOS (250 to 3000)
    2. SAW (150 to 500)
    3. VMOS (30 to 1800)
    4. EPROM (100 plus)
    5. Schottky Diodes (300 to 2500)
    1. Parts degraded/damaged by ESD may pass operational tests only to malfunction in the field when subjected to stresses. In other words, ESD damage is often difficult to diagnose/pinpoint.
    2. ESD protection devices should not be optional. ESD will cause damage most of the time unless managed properly.
    3. ESD is not a modern phenomenon; people have known about it for hundreds of years. For example, people in the 1800s took measures to make sure that black powder was safe from ESD.
    4. There are still many myths surrounding ESD. Touching metal objects to discharge oneself, for example, does not make one ready/safe to work on ESD-sensitive material. Body charges tend to rebuild right away.
    5. Inserting components into printed wiring boards (PWBs) do not make them ESD-proof.
    6. Different, especially-tailored ESD management strategies are necessary for different settings/needs.
    7. ESD problems can come from seemingly unlikely sources (e.g., charged plastic faceplates).
    8. ESD precautions are not taken by all manufacturers at all times. Because of costs involved, some manufacturers cut corners and, thus, see their products fail in the field.
    9. Everything is not presently known about ESD. Every once in a while something new is learned about ESD.
    10. ESD solutions don’t always come in neat, clearly-predictable “packages.” Periodically, creative solutions have to be found for previously un-encountered dilemmas.
    11. ESD management doesn’t always require expensive equipment and techniques. Sometimes what is required is avoiding simple errors of operation.
    12. Contact does not have to take place for ESD to be a problem. Sometimes just getting near an electric field can impart ESD effects.

     

    Conclusion

    ESD is arguably one of the most interesting aspects of electronics. Both experts and amateurs continue to be amused by what can be learned about ESD.ThinkingEngineer
