Which of the following statements about Printed Circuit Boards (PCBs) is INCORRECT?

Correct option is A

The correct answer is (a) PCBs serve only desktop computers and not portable devices.

• Printed Circuit Boards (PCBs) are a fundamental part of nearly all electronic devices, not just desktop computers. They are used in a wide range of portable devices such as smartphones, tablets, laptops, cameras, and many other electronics.

• PCBs serve to connect and support electronic components in all types of electronic devices, whether portable or stationary.

Information Booster:

• PCBs are essential in virtually all electronic devices. They provide a platform to support components such as resistors, capacitors, and integrated circuits (ICs), and they connect these components with conductive tracks.

• Multilayer PCBs are used in complex devices to increase the number of circuits that can be integrated into the board, allowing for more compact and efficient designs in devices like smartphones and computers.

• PCBs also serve the important role of heat dissipation and signal routing between components in a device.

Additional Information:

• Option B is correct as PCBs do hold and connect electronic components using conductive tracks.

• Option C is correct because PCBs provide a base to support and organize the hardware parts in electronic devices.

• Option D is correct because complex devices do indeed use multilayer PCBs to fit more circuitry and maximize space within the device.
