Building China’s PCB ‘Third Pole’: What You May Not Know About PCBs

PCB (Printed Circuit Board), known in Chinese as 印制电路板, is an important electronic component that serves as the support for electronic components and the carrier for electrical interconnections. Since it is made using electronic printing technology, it is also referred to as “printed” circuit board.

PCBs are like the nervous system of electronic devices. Just as our nerves transmit signals throughout our bodies to control our movements and sensations, PCBs transmit electrical signals between the components of devices to control their functions. Without PCBs, our electronic devices would be like bodies without a nervous system, unable to function!

The main function of a PCB is to connect various electronic components according to a predetermined circuit, serving an electrical connection role. Printed circuit boards are key interconnection components used for assembling electronic parts, providing not only electrical connections for electronic components but also carrying functions such as digital and analog signal transmission, power supply, and RF microwave signal transmission and reception. Most electronic devices and products require them, hence they are known as the “mother of electronic products.”

As the PCB industry has developed, its application fields now cover almost all electronic products, primarily encompassing communication, consumer electronics, automotive electronics, servers, industrial control, medical, and aerospace industries. The growth of the PCB industry is closely related to the development momentum of the downstream electronic information industry, with both promoting each other. In the future, as the electronic information industry continues to develop, the application fields of PCBs will become increasingly broad.

PCBs are an indispensable part of our daily lives, even if we do not always realize it. They are widely present in various electronic devices we use every day, from smartphones and computers to home appliances and vehicles.

In smartphones, PCBs provide the necessary connections between various components such as processors, memory, and sensors. They also support advanced functions such as integrated touch screens, cameras, and wireless connectivity.

In home appliances like washing machines and refrigerators, PCBs control various functions of the devices and enable programmable settings and energy-saving modes.

In vehicles, PCBs are used in various systems, such as engine control, entertainment systems, and safety features. They support advanced functions such as adaptive cruise control, lane departure warning systems, and collision avoidance systems.

In summary, PCBs play a crucial role in enabling the advanced features and functions of modern electronic devices. They are an important component of the various products we use daily, significantly impacting our everyday lives.
