Do You Know About ESD? Electric Quiz

ESD sensitive items are vulnerable to ESD damage unless they are appropriately packaged in electrostatic shielding packing materials designed for ESD control. This means that without proper packaging, these items can be easily damaged by electrostatic discharge. Therefore, the statement "ESD Sensitive (ESDS) items are susceptible to ESD damage until such time that they are properly packaged in ESD control electrostatic shielding packing materials" is true.

The entrance to an ESD control work area should have an attention sign to alert personnel that they are entering an ESD protective area. This is important because ESD (electrostatic discharge) can cause damage to sensitive electronic components. By having a sign, personnel are reminded to take necessary precautions to prevent ESD, such as wearing appropriate grounding devices and handling equipment properly. This helps to maintain a safe and controlled environment for handling electronic devices and prevents potential damage.

An ESD control workstation consists of all of the above components. It includes an ESD control work surface, which provides a grounded surface to prevent electrostatic discharge. It also includes an ESD control wrist strap, which is worn by the operator to prevent static buildup. Additionally, a common point for ground is necessary to ensure that all components are properly grounded and static electricity is effectively dissipated. Therefore, all of these components are essential for an effective ESD control workstation.

The correct answer is to disconnect power and put on an ESD control wrist strap that is bonded to the item's chassis, then remove the cover and proceed with the maintenance action. This is the correct procedure because it ensures that the power is off and that the technician is properly grounded with the ESD control wrist strap. This helps to prevent any static electricity from damaging the sensitive electronics while performing the maintenance.

Before using the job essential tools with electrically conductive tips and insulative handles on ESD sensitive items, the best approach would be to either touch the tip of the tool to the ESD work surface or touch the tip of the tool with your fingertip to dissipate any static charges through your grounded wrist strap. Both options help to prevent any static charges from damaging the ESD sensitive items.

A signed ESD control certification document should be either posted at the entrance to the ESD work area or stored in a readily accessible file. This ensures that the document is easily visible and accessible to anyone entering the area, allowing them to verify that proper ESD control measures are being followed. Hanging the document on the refrigerator is not a suitable option as it may not be easily visible or accessible to everyone who needs to see it.

Single conductor (non-constant monitored) ESD control wrist straps should be tested prior to first use daily (Only on days of actual use). This means that the wrist strap should be checked for functionality and proper grounding before it is used each day. This ensures that the wrist strap is working effectively to prevent electrostatic discharge (ESD) and protect sensitive electronic components. Testing the wrist strap on days of actual use ensures that it is in good working condition when it is needed.

An ESD control workstation work surface may be used for work that requires handling of ESD Sensitive items and work other than ESD control work provided that no ESD sensitive items remain unprotected at the workstation during this time. This means that the work surface can be used for tasks involving ESD sensitive items as well as non-ESD control work, as long as the ESD sensitive items are properly protected or removed from the workstation during non-ESD control work.

Standard single conductor wrist straps without constant monitoring require both a daily test log and a wrist strap tester. A daily test log is necessary to document the regular testing of the wrist straps to ensure they are functioning properly. Additionally, a wrist strap tester is needed to periodically test the resistance of the strap to ensure it is within acceptable limits. Both of these measures are important to maintain the effectiveness of the wrist straps in dissipating static charges and protecting sensitive electronic equipment.

ESD sensitive items need to be protected from electrostatic discharge during transportation. Packaging them in an ESD protective shielding bag or placing them in a conductive tote box with a lid can provide the necessary protection. Both options offer a barrier against static electricity and prevent potential damage to the items. Therefore, either option A or B can be chosen for transporting ESD sensitive items.

The correct answer is to ensure that the ESD sensitive item is properly packaged in an ESD shielding bag or placed in an ESD tote box with a lid before removing it from the ESD control workstation. This is because without the ESD control wrist strap and an ESD flooring system, the item is at risk of being exposed to static electricity, which can damage sensitive electronic components. Proper packaging in an ESD shielding bag or tote box with a lid helps to prevent static electricity from reaching the item and causing damage.

Static generating materials may be present at the ESD control workstation with ESD sensitive items if they are job essential. This means that if the materials are necessary for the completion of the job or task at hand, they can be allowed in the workstation despite their potential to generate static electricity. However, it is important to ensure that proper ESD control measures are in place to minimize the risk of damage to the sensitive items.

ESD sensitive items should only be handled at an ESD control workstation because these workstations are specifically designed to minimize the risk of electrostatic discharge. They are equipped with various measures such as grounded surfaces, wrist straps, and ionizers to prevent the build-up and discharge of static electricity. Handling ESD sensitive items at these workstations ensures that proper precautions are taken to protect the items from potential damage caused by electrostatic discharge.
