Electrostatic Discharge Awareness Quiz

To control ESD (electrostatic discharge) in the work area, it is important to avoid touching static generating materials, refrain from shuffling your feet when walking, and avoid combing your hair. All of these actions can generate static electricity, which can lead to ESD and potentially damage sensitive electronic components. By following these precautions, the risk of ESD can be minimized in the work area.

If ESD (Electrostatic Discharge) is not controlled, it can lead to various negative consequences. Unhappy customers may be a result of damaged or malfunctioning products due to ESD. Lower product quality can occur because ESD can cause defects or impair the functionality of products. Additionally, ESD can increase costs as it may require repairing or replacing damaged products. Therefore, all of the mentioned outcomes are likely to happen if ESD is not controlled.

If you are not sure whether a device is ESD sensitive or not, it is safer to treat it as if it were ESD sensitive. This means taking necessary precautions and handling the device with ESD-safe procedures to minimize the risk of damaging it. Treating it like any other device or including it in the scrap report may lead to potential damage if the device is indeed ESD sensitive. Therefore, it is best to err on the side of caution and assume that the device is ESD sensitive until proven otherwise.

A conductor is a material that allows the flow of electrical current through it. It has free electrons that can easily move and carry the electric charge. Unlike insulators, conductors have low resistance and do not impede the flow of current. Therefore, the correct answer is that a conductor allows the flow of electrical current.

The correct answer is "all of the above". This means that all the options listed (tape dispensers and hair brushes, vinyl binders and plastic covers, Styrofoam cups and plastic safety glasses) are examples of non-conductive, static generating materials.

Personal grounding helps control ESD by draining charges before they reach the ESD sensitive device. This means that any static charges that may be present on a person's body are safely discharged through a grounding system, preventing them from transferring to the electronic assembly and potentially causing damage. By ensuring that individuals are properly grounded, the risk of ESD incidents is minimized, allowing for a more controlled and safe working environment.

When two objects with different charges come close together, static electricity rapidly moves from one object to another. This is because objects with opposite charges attract each other, causing the transfer of electrons and the flow of static electricity.

Insulators are materials that do not allow the flow of electricity easily. They have high electrical resistance, which means they resist the flow of electric current. Unlike conductors, which allow electricity to pass through them easily, insulators prevent the flow of electrons. This property makes insulators useful for protecting against electric shocks and preventing unwanted electrical currents. Therefore, the statement "resist the flow of electricity" accurately describes the behavior of insulators.

To reduce the effect on non-conductive items in the workplace, it is recommended to apply an anti-static solution, operate with controlled humidity, and use an air ionizer. Applying an anti-static solution helps to neutralize static charges on surfaces, preventing them from damaging non-conductive items. Operating with controlled humidity helps to minimize the buildup of static electricity in the air, reducing the risk of damage to non-conductive items. Using an air ionizer helps to create a balanced ion environment, further reducing static charges in the air and protecting non-conductive items. Therefore, all of the above options are effective in reducing the effect on non-conductive items in the workplace.

Devices damaged by ESD may work initially because the damage caused by electrostatic discharge may not be immediately visible or noticeable. However, over time, the damage can accumulate and eventually cause the device to fail. Therefore, devices damaged by ESD may work at first, but are likely to fail later.

Moving materials against each other will create an electrostatic charge. When two materials are rubbed together, electrons can be transferred from one material to another, creating a charge imbalance. This charge imbalance results in the buildup of static electricity, which can cause objects to attract or repel each other.

ESD sensitive components can be damaged by as little as 20 volts. This means that even a small electrostatic discharge of 20 volts can cause harm to these components. It is important to handle them with caution and take necessary precautions to prevent ESD damage.

When transporting ESD sensitive devices, it is important to use closed containers and carts that are specifically designed for ESD sensitive devices. This is because these containers and carts are made with materials that can effectively dissipate static electricity and prevent ESD damage to the devices. Using regular containers and carts may not provide the necessary protection and can increase the risk of ESD damage during transportation.

Most people feel ESD (Electrostatic Discharge) above 2,000 volts. This suggests that the threshold for individuals to perceive an electric shock or static electricity is relatively high, requiring a significant amount of voltage to be felt. It is important to note that sensitivity to ESD may vary among individuals, and some people may be more sensitive to lower voltages. However, the given answer implies that the majority of people typically experience the sensation of ESD at or above 2,000 volts.

Cotton is the best choice of material to wear in order to control ESD (Electrostatic Discharge). Cotton is a natural fiber that does not generate static electricity easily, unlike synthetic materials such as rayon and polyester. Wool, although a natural fiber, can generate static electricity due to its insulating properties. Therefore, cotton is the most suitable option for minimizing the risk of ESD.

The wrist strap needs to be worn snugly against the skin to ensure proper grounding. It also needs to be able to be quickly connected or disconnected for convenience. Additionally, it should be attached securely to a ground wire with a current limiting resistor to prevent excessive current flow in the event of a static discharge. Therefore, all of the above options are necessary for an effective wrist strap.

A sealed static shielding bag is designed to provide protection against electrostatic discharge (ESD) damage. ESD can occur when there is a sudden flow of electricity between two objects with different electrical potentials, such as when a person touches an electronic device. This discharge can cause damage to sensitive electronic components, leading to malfunctions or failure. By using a static shielding bag, the enclosed device is protected from ESD damage by preventing the flow of electricity between the device and external sources.

If you experience a problem when testing your wrist strap or shoe grounders, it is important to let your supervisor know immediately. This is the correct answer because notifying your supervisor allows them to address the issue and ensure that you are properly grounded to prevent electrostatic discharge. It is crucial to maintain a safe working environment, and your supervisor is responsible for addressing any problems or concerns related to equipment and safety protocols.

Static dissipative materials are designed to conduct electricity, but at a slow enough rate that it does not cause damage to ESD (electrostatic discharge) sensitive devices. These materials provide a controlled path for the flow of static electricity, allowing it to safely dissipate without causing harm to electronic components. This is important in environments where ESD sensitive devices are handled, as a sudden discharge of static electricity can cause permanent damage.

Static electricity is best described as an electrical charge at rest. This means that the electrical charge is not flowing or moving, but rather it is stationary. Static electricity occurs when there is an imbalance of electrons on an object, causing it to become positively or negatively charged. This charge remains in place until it is discharged or neutralized.

Shoe grounders are most effective for operations that require movement because they are designed to provide a continuous path to ground for static electricity. When a person wearing shoe grounders walks or moves around, any static charge that builds up on their body is safely discharged to the ground through the conductive sole of the shoe grounder. This helps to prevent static discharge, which can damage sensitive electronic components or cause safety hazards in certain work environments. Therefore, shoe grounders are particularly beneficial for operations that involve constant movement, as they ensure a continuous grounding connection.

Components should be handled only by the non-conductive portion of the body to prevent any potential damage caused by static electricity. The non-conductive portion of the body, such as the back of the hand or fingers, helps to minimize the risk of static discharge that could harm the components. By avoiding direct contact with the conductive parts of the body, the chances of transferring static electricity to the components are significantly reduced. This precaution is crucial in protecting sensitive electronic components from potential damage.
