With the continuous progress of electronic information technology, PCB industry has gained great development in all aspects. This paper elaborates on the current situation and future trends of the PCB industry from four aspects: demand, technology, market and policy. Among them, the demand aspect mainly includes 5G network, Internet of Things, and smart car, while the technology aspect introduces the direction of flexible circuit boards and lead-free process. The market aspect emphasises the domestic and international competition and China's increasing position in the PCB industry chain. Finally, policy guidance will also become an important factor for the healthy development of the PCB industry in the future.

1, Demand

PCB industry is widely used in various fields, among which the rapid development of 5G network has become an important driving force for PCB industry.The large-scale commercialisation of 5G network will bring more terminal equipment, communication equipment and base stations, which requires PCB enterprises to expand their production capacity to meet the market demand. Meanwhile, the development of emerging industries such as the Internet of Things, smart homes, and smart cars has also brought new opportunities and challenges to the PCB industry.

Flexible circuit boards have also become a major trend on the demand side. With the increasing demand for thin, light, smart and mobile products, flexible circuit boards are gradually replacing rigid circuit boards and becoming mainstream products in the market. In the future, companies need to continue to improve the technical level, to develop a more competitive flexible circuit board products.

In addition, under the impetus of the green manufacturing concept, the lead-free process has become an important development direction in terms of future demand. On the one hand, the lead-free process can improve the performance and reliability of PCB products; on the other hand, the lead-free process meets the requirements of environmental protection, but also an important direction for the sustainable development of the PCB industry.

2、Technology

PCB industry's technology level is increasing, in which flexible circuit boards, HDI boards, plastic packaging and other directions to become a hot spot for technological innovation.

Flexible circuit boards are an important trend in the future PCB industry. Flexible circuit boards have excellent flex resistance and small size, easy to install and other characteristics, can be widely used in mobile phones, laptops, tablet PCs, smart homes, smart cars and other products. In the future, PCB companies will need to continue to develop new flexible circuit boards and improve manufacturing capabilities and quality standards.

The emergence of HDI boards also brings new opportunities for the PCB industry, HDI boards have high precision, high density and other characteristics, which can meet the market requirements for miniaturisation, lightweight, high functionality. In the future, HDI boards will be widely used in 5G communication, smart home and other fields, becoming an important product in the future PCB market.

The application of plastic packaging technology in the PCB industry has also become a direction of technological innovation. Plastic packaging technology can improve packaging density, reduce costs, while avoiding the use of toxic and hazardous substances, in line with environmental protection and sustainable development requirements. In the future, plastic packaging technology will become an important development direction of the PCB industry.

3、Market

Global thinking, technology-driven acceleration of the PCB industry's international exchanges and cooperation, market competition is becoming increasingly fierce. Especially in the context of rapid development of information technology, the PCB industry has become an important and indispensable element of the global electronics manufacturing industry.

At present, North America, Europe and Asia are the main regions of the PCB market. In recent years, the PCB industry in the United States, Japan and other developed countries have gradually shifted to high value-added, high-end market, while China's PCB market is expanding and developing strongly. China's PCB industry is developing rapidly and competitive globally, and China's position and influence in the global PCB industry chain will continue to increase in the future.

At the same time, there are still some problems in the PCB market, such as chaotic demand chain management, supply chain fluctuations and so on. In the future, PCB enterprises should improve their competitiveness, achieve high quality, high quality, low-cost production, and provide customers with more comprehensive and professional services.

4、Policy

Policy environment is an important factor in the healthy development of the PCB industry. Many countries and regional governments have put forward the PCB industry's industrial policy, environmental policy, etc., in order to promote the PCB industry to meet market demand and promote the healthy and orderly development of the industry.

At present, the Chinese government has increased its support for the information technology industry and promoted the rapid development of the PCB industry through a series of policy measures. In the future, the policy environment will further guide the healthy development of the PCB industry, and prompt enterprises to focus on protecting the environment and achieving sustainable development.

Summary:

With the continuous development of electronic information technology, the PCB industry will take flexible circuit boards, HDI boards, plastic packaging and other technological directions as a breakthrough to meet the market demand for miniaturisation, Internet of Things, environmental protection and so on. At the same time, the international market competition will become more and more intense, China's position and influence in the global PCB industry chain will continue to improve. Future policy guidance will also become an important factor in the development of the PCB industry, prompting companies to focus on environmental protection and sustainable development.
