Thermal Management Quiz

What is the purpose of doing thermal management in microelectronic’s packaging?

• To generate more heat

• To improve reliability and prevent premature failure

• To increase power consumption

• To reduce the efficiency of the device

Explain the definition of catastrophic failures?

• Gradual loss of electronic function

• Immediate and total loss of electronic function and package integrity

• Increase in electronic function

• Enhancement of package integrity

What are the differences between passive cooling technique and active cooling technique?

• Active cooling is less effective in dissipating heat compared to passive cooling

• Passive cooling does not require any external power source, while active cooling does

• Passive cooling is more efficient than active cooling

• Passive cooling requires electricity, while active cooling does not

List down the cooling methods that are used in electronics components.

• Heat sinks, Thermal Vias, Jet Impingement cooling

• Conductive cooling, Convective cooling, Radiative cooling

• Immersion Cooling, Air cooling, Liquid cooling

• Fan cooling, Vacuum cooling, Radiative cooling

Explain briefly about heat sinks.

• Heat sinks are used to increase power consumption

• Heat sinks transfer thermal energy from a high-temperature object to a lower temperature object

• Heat sinks are made of plastic materials

• Heat sinks are not effective in dissipating heat

Explain briefly thermal vias.

• Thermal vias are used for air cooling

• Thermal vias are used to reduce the resistance to heat flow in a specific direction

• Thermal vias are not effective in thermal management

• Thermal vias are made of gold and silver

Explain the immersion cooling method in the thermal management system.

• Immersion cooling uses air as the cooling medium

• Immersion cooling operates in an open loop system

• Immersion cooling is used to increase the solid-solid interface resistance

• Immersion cooling eliminates the solid-solid interface resistance and operates in a closed loop system

Which of the following is NOT a cooling method used in electronics components?

• Vacuum cooling

• Thermal Vias

• Heat sinks

• Jet Impingement cooling

What is the primary aim of electronics thermal management?

• To reduce the efficiency of the device

• To enhance the reliability of the device

• To prevent catastrophic failure

• To increase the temperature of the operating component

Which level of packaging is considered as the Third Level Package?

• Second Level Package (Printed Wiring Board, PWD)

• First Level Package (Multichip Module)

• Single Chip Module

• Third Level Package (Motherboard or backplane)
