Testing Supervisor Interview Questions and Answers

A heat sink is used to dissipate heat generated by electronic components to prevent overheating.

• Heat sinks are commonly used in computers to cool the CPU and GPU.

• They work by transferring heat from the component to the heat sink, which then dissipates it into the surrounding air.

• Heat sinks are typically made of metal with fins to increase surface area for better heat dissipation.

PCB failure can be caused by various factors such as overheating, moisture exposure, component defects, and poor soldering.

• Overheating due to excessive current or poor ventilation

• Moisture exposure leading to corrosion or short circuits

• Component defects such as faulty capacitors or resistors

• Poor soldering causing weak connections or shorts

PCB boards are used in electronic devices to provide mechanical support and electrical connections for various components.

• PCB boards provide a sturdy base for mounting electronic components.

• They offer a reliable way to connect different components through copper traces.

• PCB boards help reduce the size and weight of electronic devices.

• They allow for automated assembly processes, increasing efficiency and reducing costs.
