Before transporting an ESD sensitive device, it must be:- (pick 1)

Thoroughly cleaned
Put into a static shielding bag or packet
Put into a cardboard box or container
Wrapped in paper

Correct Answer

A. Put into a static shielding bag or packet

Explanation

When transporting an ESD sensitive device, it must be put into a static shielding bag or packet. This is because ESD (electrostatic discharge) can damage electronic components and circuits, and static shielding bags or packets are designed to prevent the buildup and discharge of static electricity. These bags or packets are made of materials that provide a barrier against electrostatic fields, protecting the device from potential damage during transportation. Thoroughly cleaning the device, putting it into a cardboard box or container, or wrapping it in paper do not provide the same level of protection against ESD.

If the humidity is too high, equipment can suffer from .................... damage (1 word)

Correct Answer
moisture
water
condensation

Explanation
If the humidity is too high, it can cause moisture, water, or condensation to accumulate on equipment. This can lead to damage as the excess moisture can corrode or short-circuit electronic components, causing them to malfunction or fail. It is important to control humidity levels in order to protect equipment from this type of damage.

What does MSDS stand for? (4 words)

Correct Answer
material safety data sheet

Explanation
MSDS stands for Material Safety Data Sheet. This document provides detailed information about the potential hazards and safe handling procedures for a specific substance or product. It includes information about the composition, physical and chemical properties, health effects, first aid measures, and disposal methods. MSDS is an important tool for ensuring the safety of workers and the proper handling and storage of hazardous materials.

When environmental conditions are dry and cool, what is ESD probability? (pick 1)

Low
High

Correct Answer

A. High

Explanation

In dry and cool environmental conditions, the probability of experiencing ESD (electrostatic discharge) is high. This is because low humidity and lower temperatures can increase the accumulation of static electricity, making it more likely for ESD events to occur.

This is used to prepare a hard drive to store information. (pick 1)

Fdisk
Defrag
Disk cleanup
Format

Correct Answer

A. Format

Explanation

Format is the correct answer because it is the process of preparing a hard drive to store information. When a hard drive is formatted, it is divided into sectors and tracks, and a file system is created to organize and manage the data. This allows the hard drive to be ready for storing files and data in a structured manner.

A .......... ................ is sometimes called a nut driver. (2 words)

Correct Answer
hex driver
hex screwdriver

Explanation
A hex driver or hex screwdriver is sometimes called a nut driver because it is a tool used to tighten or loosen nuts and bolts with hexagonal heads. The term "hex" refers to the shape of the head, which has six sides. The driver or screwdriver is the tool used to apply torque to the nut or bolt, allowing it to be tightened or loosened. Therefore, both "hex driver" and "hex screwdriver" are correct answers for this question.

When cleaning the gold contacts on computer components, what is the best substance to use? (pick 1)

A mild cleaning solution
Compressed air
A nylon brush
Isopropyl alcohol

Correct Answer

A. Isopropyl alcohol

Explanation

Isopropyl alcohol is the best substance to use when cleaning the gold contacts on computer components because it is a mild and effective cleaning solution that evaporates quickly and leaves no residue. It is also safe to use on electronic components and does not cause damage or corrosion. Compressed air may remove loose debris but does not effectively clean the contacts. A nylon brush may cause scratches or static buildup.

This is a dramatic increase in voltage abvove the normal flow of electical current that lasts for a few nanoseconds. (pick 1)

A blackout
A spike
A power surge
A brownout

Correct Answer

A. A power surge

Explanation

A power surge refers to a sudden and significant increase in voltage that exceeds the normal flow of electrical current. It typically lasts for a short duration, usually a few nanoseconds. This increase in voltage can cause damage to electronic devices and appliances connected to the power supply. It is important to protect sensitive equipment from power surges using surge protectors or uninterruptible power supplies (UPS).
