ESD Equipment

  • Why is ESD Prevention Important?

    Our latest blogs have discussed many things involving ESD- ESD flooring and maintenance, ESD bags, and ESD devices such as heel grounders. We’ve explained how important it is to maintain an ESD-safe environment, but why is it so important? Today, we’re going to dive into why electrostatic discharge can be as simple as a shock you feel on a cold, dry day, or as serious as a shock that ignites flammable mixtures or ruins electronic components in your workspace.

    It’s true, electrostatic shock can be harmless. The sudden
    jolt you sometimes get after touching a car door or the hand of another person
    can be a little painful, but most of the time it brings a good laugh,
    especially when it startles you or the person you touched. Electricity is
    constantly passing back and forth between ourselves and objects, but the
    voltage is often times too low to feel. It typically takes a voltage of at
    least 3,000 for people to detect the shock.

    On the flip side, it only takes 30 volts to damage highly
    sensitive electronic components, while most components are at risk when the
    charge is between 100 and 200 volts. With that being said, electronic shocks
    that are undetectable to humans have the capability to damage or destroy your
    electrical equipment.

    There are two types of damages that your equipment could
    experience as a result of ESD events- immediate or delayed damage. With delayed
    damages, you could see a malfunction of your device at any point of its
    lifespan. This is also known as a latent defect. These are harder to identify,
    as the component might continue to perform its function for a certain period of
    time, but ultimately the operating life will be reduced dramatically.

    The second type of damage is the immediate damage, otherwise
    known as catastrophic failure. This is when the device is damaged and fails
    immediately. The damages are permanent and the electronic component is
    essentially destroyed. 

    If you work in any industry, there are two things you want to save- time and cost. The same could be said for the electronic assembly industry. If you subject yourself to ESD damages, you’re ultimately wasting both your time and your money. Don’t worry, though. There are many different ways to prevent ESD damages and keep your workspace controlled:

    1. ESD Mats and Flooring

    SCS ESD Floor Mat

    ESD matting and flooring work to disperse the electricity created when your feet make contact with the ground. We wrote an entire blog about the different types of ESD flooring and how to maintain it to ensure that you receive the best possible results, so check that out here.

  • Difference Between Metal-In and Metal-Out ESD Bags

    In previous blogs, we’ve discussed how important it is to take care of sensitive materials and devices by ensuring that your work environment is ESD safe. Today we’re going to dive into the differences between two commonly used ESD protection bags- the metal-in and metal-out bags.

    Both types of bags are conductive, or metalized, and comprised of multiple layers that make up a protective shield. The protective shield works to keep electrostatic discharge generated by surfaces, other materials and the user from making contact with ESD sensitive devices. With that being said, both are different in their overall makeup as well as their best uses and features.

    Metal-In ESD Bags

    The more commonly used of the two is the metal-in shielding bag. Like it’s name would suggest, metal-in bags feature a metal shield closer to the middle, or inside, of the bag. The metal shield lies within a layer of static dissipative polyethylene and polyester. Typically speaking, the metal-in bags gain the edge when it comes to cost and durability. They last longer than metal-out bags as they are less likely to scratch and they’re more commonly found on the market.

    Metal-Out ESD Bags

    In metal-out bags, the layer of metal is closer to the outside surface of the bag in between the polyester and the abrasion resistant coating. Because of this, this type of bags have a lower resistance reading and can dispel a static charge faster than metal-in bags can. They’re most commonly used in critical electronics applications and disk drive manufacturing and are most recommended for operations where faster charge decay is preferred.

    While there’s no direct answer to which type of bag you should buy, it will depend on your budget, the materials you use and the types of operations you perform. If you have any additional questions about metal-in and metal-out bags, be sure to give us a call. You can shop our inventory of ESD protection bags here.

  • Why Use Ionizers

    You’ve heard about ionizers before...but do you really need them? If you want to protect your workstation from electrostatic discharge (ESD), then the answer is most likely yes.

    Certain preventative measures can be taken to protect your workstation from electrostatic discharge. In order to maintain a proper ESD control program you will sometimes need to use additional equipment -- this is where the ionizer comes into play.

    Below, we’ll go over four methods for reducing electrostatic discharge both with and without the use of an ionizer to show you the difference.

    Three Ways to Reduce Electrostatic Discharge Without an Ionizer

    In an ESD protected area, insulators can be controlled by doing the following:

    1. Use insulators and maintain a perimeter
    In addition to using a grounded work surface, be sure to use insulated items. These insulated items should be a minimum of 30 centimeters away from all ESD sensitive items at all times.

    2. Use ESD protective items
    To add an extra layer of precaution, replace your insulative items with fully ESD protected versions. For example, instead of using a regular drinking cup at your workstation, replace it with a fully insulated thermos.

    3. Periodically apply topical anti-static agent
    For items which cannot be replaced with an ESD protected version, protect against electrostatic discharge by periodically applying a topical anti-static agent. Examples of such items might be your keyboard.

    Why use an ionizer

    When none of this is possible, the insulator is termed process essential and therefore neutralization using an ionizer should become a necessary part of the ESD control program.

    How ionizers remove electrostatic discharge
    While conductive items can be discharged of their negative ions by being placed on a grounded surface, an insulator will still maintain a positive charge when placed on a grounded surface. Here’s an example:

    This instrument is a digital static field meter which measures voltages associated with electrostatic charge. If we rub two paddles together -- one an insulator and the other a conductor -- and hold them over the field meter the meter shows that the insulated paddle holds many thousands of volts, which in this case is a positive charge.

    The conductive paddle holds a much lower negative charge but it is still charged.

    If we place both paddles on a grounded surface and hold them over the field meter again, the insulator is still holding a large positive charge.

    However the conductor is no longer holding a charge. By placing the conductor on a grounded surface the charge was transferred to the mat and away to the ground.

    An ionizer can help maintain an ESD protected workstation for both insulators and conductors.

    Once the ionizer is turned on it sends out thousands of matching pairs of both positive and negative ions in the air flow. If we hold the positively charged insulative paddle into the air flow it will attract negative ions thereby neutralizing the charge on the surface.

    It’s like magic...or better yet, science!

    Still have questions? Watch our instructional video to learn more about why you should use ionizers here.

    What size ionizer is best?
    The size of the ionizer needed depends on the size of your workstation. For small workstations and desktops not more than 1-4 feet, a single-fan ionizer will work. For larger workstations or a grouping of desktops, several overhead multi-fan ionizers may be more suitable. As a supplement, or to reach small interior areas and remove lodged debris, a point-and-shoot ionizer or ionizer gun works best.

    Shop these and other ESD protective items for your manufacturing workspace from KIMCO’s ionization equipment.

  • 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.
