Which of the following protects from electrostatic discharge ESD?

Which of the following protects from electrostatic discharge ESD?

Answer: A. Technicians protect the equipment from electrostatic discharge by using grounding strap devices that are placed around the wrists or ankles to ground the technicians to the system being worked on. These straps release any static present on a technician’s body and pass it harmlessly to ground potential.

When working with a computer which of the following best protects against ESD?

When working on a computer, you should use a grounding strap to protect the component from ESD damage.

What impact does ESD have on computer equipment?

ESD is a major concern for any company manufacturing electronic equipment. The damage caused by static discharges can cause a component to fail immediately and also it can cause latent failures to occur which can manifest themselves later, considerably reducing the overall reliability of the product.

Which of the following hardware is used to prevent ESD?

The best method of preventing ESD is to use an ESD wrist strap, grounding mat, or grounding workbench. However, because most users don’t have access to such items, we’ve included the following steps to reduce the chances of ESD as much as possible.

How can ESD sensitive devices be damaged by ESD?

An electrostatic-sensitive device (often abbreviated ESD) is any component (primarily electrical) which can be damaged by common static charges which build up on people, tools, and other non-conductors or semiconductors.

What tools prevent ESD damage to computer equipment?

1.2) There are two ESD tools: the antistatic wrist strap and the antistatic mat. The antistatic wrist strap protects computer equipment when grounded to a computer chassis. The antistatic mat protects computer equipment by preventing static electricity from accumulating on the hardware or on the technician.

Which of the following are guidelines for protecting components from ESD damage?

Use a grounded conductive workbench mat and a grounding wrist strap, and ground the equipment to the mat. Never place components on any metal surface. Metal surfaces can hold a static charge that will damage sensitive electronic parts. Use antistatic, conductive, or foam rubber mats.

When troubleshooting a computer hardware problem which tool might help with the following problem you suspect the network port on a computer is not functioning?

A network port is not functioning on a computer. The tool that can be used to check if the network port is functioning properly or not is loopback plug. If the lights on either side of the network port lit up then the network port is functioning properly. Refer to the Figure 1-44 for a loopback plug.

Which device is ESD sensitive?

Common electrostatic-sensitive devices include: MOSFET transistors, used to make integrated circuits (ICs) CMOS ICs (chips), integrated circuits built with MOSFETs. Examples are computer CPUs, graphics ICs.

What categories of damage ESD can cause in electronic devices?

TYPES OF ESD DEVICE DAMAGE

• Catastrophic Failures.
• Latent Defects.

What causes ESD in computer?

Causes. One of the causes of ESD events is static electricity. Static electricity is often generated through tribocharging, the separation of electric charges that occurs when two materials are brought into contact and then separated. ESD can also be caused by energetic charged particles impinging on an object.

What is computer ESD tools?

ESD Tools (2.2. There are two ESD tools: the antistatic wrist strap and the antistatic mat. The antistatic wrist strap protects computer equipment when grounded to a computer chassis. The antistatic mat protects computer equipment by preventing static electricity from accumulating on the hardware or on the technician.

What kind of damage can be caused by ESD?

Processors and memory are most susceptible to damage caused by Electrostatic Discharge (ESD). The small size and small power requirements of these components means that the charges associated with ESD can easily damage the circuitry.

Why are some electronic devices more sensitive to ESD?

It is found that some electronic devices are more sensitive to ESD than others. However to put the problem in perspective it is worth relating the levels of static to those to supply voltages. One would not consider applying a voltage of even fifty volts to a logic device.

Is the Cat 5 cable susceptible to ESD?

CRT monitors are susceptible to damage caused by magnetic fields, but LCD/LED monitors are not susceptible to magnetic fields or to ESD. Cat 5 cables are susceptible to EMi (interference caused by electrical signals). Fiber optic cables are immune from EMI.

How are new microprocessors affected by ESD?

However many of the new microprocessors and LSI chips use very much smaller feature sizes, and cannot withstand anything like these voltages, making them very sensitive to ESD. Many new devices would be destroyed by operating them with a supply voltage of 5 V, and they are corresponding more susceptible to damage from ESD.
