The PCB industry has developed to this day, and its application fields almost involve all electronic products, mainly including communication, aerospace, industrial control and medical, consumer electronics, automotive electronics, and other industries. The growth of the PCB industry is closely related to the development momentum of the downstream electronic information industry, and the two promote each other.

Specifically, network communication, computers, and consumer electronics have become the three main application areas of PCBs. Thanks to the development of 5G communication technology and the trend of new energy vehicles and automotive intelligence, automotive electronics has become one of the fastest growing areas for PCB applications With the continuous development of the electronic information industry in the future, the application fields of PCBs will become increasingly widespread.

(1) Overview of the main products and PCB product structure in the industry

According to different electronic device usage requirements, PCBs can be divided into six main sub products from the perspectives of layer count and technical characteristics, including single panel, double-sided board, conventional multi-layer board, flexible board, HDI (high-density interconnect) board, and IC packaging substrate.

According to the final demand classification of printed circuit boards, they can be divided into enterprise level user needs and individual consumer needs. Among them, the demand for enterprise level users is mainly concentrated in fields such as communication equipment, industrial control medical, and aerospace. Relevant PCB products often have characteristics such as high reliability, long service life, and strong traceability. The qualification certification for corresponding PCB enterprises is more strict and the certification cycle is longer. The demand for individual consumers is mainly concentrated in fields such as computers, mobile devices, and consumer electronics. Relevant PCB products are usually lightweight and miniaturized Capable of writing and other characteristics, resulting in a high demand.

From Quan Qiong's perspective. According to Pisman's data, currently, mid to multilayer boards still dominate the PCB market. With the rapid development of technology in the electronic circuit industry, the integration functions of components are becoming increasingly widespread, and the high-density requirements for PCBs in electronic products are becoming more prominent. High alcohol PC8 products such as multilayer boards, HOI boards, flexible boards, and packaging substrates are gradually occupying a more important position in the market. From various product categories, in 201, the output value of full ring multilayer boards and HIO acid was 3105.3 billion US dollars and 115 yuan, respectively. Among them, the growth rate of multilayer boards with 8-16 layers was faster, The growth rate of high multi layer boards reaching 280% and above 18 layers is 20.70%. The growth rate of HDI boards is 19.60%.

From a domestic perspective, although there are still relatively few domestic manufacturers producing high-tech products such as high multi layer boards, HOI versions, and packaging substrates, the proportion of such products has been increasing year by year. In addition, according to Prismak's prediction, the growth rate of output value of various segmented products in the Chinese PCB industry in the future is higher than the global average, especially for high-tech PCBs represented by high multilayer boards, HDI boards, flexible boards, and packaging substrates

Taking packaging substrates as an example, the compound annual growth rate of China's packaging substrate output value from 2016 to 2020 was about 550%, while the global average level was 0.10%, indicating a clear trend in industrial transfer.

(2) Import and export situation of China's PCB industry

In recent years, against the backdrop of slowing global economic growth, China's PCB output value and proportion have been increasing year by year.

From the perspective of product structure, China mainly exports mid to low-end PCB products, while imports mostly include mid to high-end PCB products such as high multilayer boards, HDI boards, flexible boards, and packaging substrates. But with the continuous strengthening of China's PCB enterprises, the product structure of import and export in the PCB industry has gradually changed.

(3) Industrial distribution of PCB industry

In the past decade, the proportion of the output value of PCBs in the Americas, Europe and Japan in the world has continued to decline. At the same time, the global share of the output value of PCBs in Chinese Mainland has continued to rise. According to Prismark and the China Economic Industry Research Institute, the proportion of the output value of PCBs in Chinese Mainland in the global output value will rise to 54.63% in 2021, up 0.40 percentage points from the previous year. In addition, the global share of PCB output value in other Asian regions except Chinese Mainland also rose slowly. The production capacity of the global PCB industry (especially high-tech PCBs such as high multilayer boards, flexible boards, and packaging substrates) is gradually concentrated in the Asian region represented by Chinese Mainland.

At present, China has formed a PCB industry cluster belt with the Pearl River Delta region and the Yangtze River Delta region as the core areas. In recent years, with the increase in labor costs in coastal areas, some PCB companies have begun to relocate their production capacity to cities in the central and western regions with better basic conditions, such as Huangshi in Hubei, Guangde in Anhui, and Suining in Sichuan. Due to their talent advantages, economic advantages, and industrial chain supporting advantages, the Pearl River Delta and Yangtze River Delta regions are expected to maintain a leading position in the PCB industry in the future and continue to develop towards high-end and high value-added products. In addition, the central and western regions will gradually become important industrial bases for China's PCB industry due to the relocation of PCB enterprises.
