The main application fields of the circuit board industry are very extensive, covering multiple aspects such as communication, consumer electronics, and automotive electronics, as detailed below:

1. In the field of communication, it is applied to routers, switches, base stations, optical fiber transmission equipment, etc. This field has high requirements for PCBs, usually requiring precise impedance control, high reliability, and strong heat dissipation capabilities to support large-scale data transmission and processing. Representative technologies include high-frequency PCBs, high-speed PCBs, and multi-layer boards.

2. In the field of consumer electronics, it encompasses products such as smartphones, tablets, smartwatches, and household appliances. Consumer electronic devices aim for miniaturization and lightweight design, thus often employing high-density interconnect (HDI) and flexible printed circuit boards (FPC). Additionally, they must possess high reliability and durability to withstand wear and thermal effects during prolonged use.

3. In the automotive electronics field, it involves automotive control systems, autonomous driving, entertainment systems, electric vehicle charging modules, etc. The working environment of automotive electronic products is complex, requiring PCBs to have high heat resistance, vibration resistance and anti-interference capabilities. Electric vehicles have also promoted the application of thick copper PCBs.

4. In the field of medical equipment, such as heart monitors, MRI machines, and ultrasound devices, etc., medical equipment PCBs require high precision, high reliability, and strict safety standards to ensure the accuracy and stability of the equipment. With the miniaturization trend of medical equipment, the application of flexible PCBs is also increasing.

5. In the field of industrial control, it is used in factory automation equipment, robots, motor control, programmable logic controllers (PLCs), etc. The environment where industrial control equipment is located is relatively harsh, requiring PCBs to be resistant to high temperatures and chemical corrosion, while also having good anti-electromagnetic interference capabilities and physical strength.

6. In the aerospace and defense sector, it is applied in radar systems, satellite communications, missile control systems, etc. PCBs in this field usually need to operate in extreme environments, and the manufacturing process must comply with strict quality standards, often using special materials such as ceramic substrates.

7. In the field of computing and data storage, which encompasses servers, data centers, storage devices, etc., the development of cloud computing and big data has placed higher demands on the high-speed signal transmission, low latency, and high reliability of PCBs. As a result, high-speed PCBs and multi-layer PCBs are widely used.

8. In the field of smart home, such as smart speakers, smart lighting, security devices, etc., the PCBs of smart home products need to have wireless connection functions, and integrate multiple sensors and communication modules. Miniaturization and low power consumption are their core requirements.

9. In the field of lighting systems, it is mainly used in LED lighting, automotive lighting, etc. The PCBs in LED lighting systems typically employ metal substrates to enhance heat dissipation performance, ensuring the stable operation of LED chips and extending the lifespan of the equipment.
