Printed circuit board (PCB) refers to the use of printing technology to form a conductive circuit pattern or a functional board containing printed components on an insulating substrate according to a predetermined design, which is used to realize the interconnection and relay transmission between electronic components. It is an indispensable basic component of electronic information products. There are many kinds of PCBs, which can be divided into rigid board (R-PCB), flexible board (FPC), and rigid-flex board according to the flexibility of the substrate; according to the number of layers of the conductive pattern, it can be divided into single-sided board, double-sided board, In addition, there are special product classifications, such as high-speed high-frequency boards, high-density connection boards (HDI), packaging substrates, etc.
1. Global PCB downstream application field structure
The printed circuit board is a bridge that carries electronic components and connects circuits to form a module or finished product with specific functions. It is irreplaceable in the entire electronic product and is known as the “mother of electronic products”. Printed circuit boards are widely used in communication electronics, consumer electronics, computers, new energy automotive electronics, industrial control, medical equipment, national defense and aerospace, and are indispensable electronic components in modern electronic information products. In 2021, the world’s largest PCB downstream application will be in the communication field, accounting for 32%; followed by the computer industry, accounting for 24%; consumer electronics, accounting for 15%; server industry accounting for 10%; industrial control industry Accounted for 4%; the military aviation industry accounted for 4%, and the medical industry accounted for 2%.
2. The scale and growth of global PCB output value
The PCB industry belongs to the basic industry of electronic information product manufacturing and has a high correlation with the macroeconomic cycle. At present, global printed circuit board manufacturing enterprises are mainly distributed in mainland China, Taiwan, Japan, South Korea, Southeast Asia, the United States and Europe. In 2021, the global epidemic will be repeated and the economy will fluctuate. However, the outbreak of 5G communications and terminals, new energy vehicles, consumer electronics and other markets will drive the growth of the PCB industry against the trend. According to statistics, the output value of the global PCB industry will reach US$80.9 billion in 2021, a year-on-year increase of 24.08%.
3. Global PCB subdivision product structure
With the rapid development of technology in the world’s electronic circuit industry, the application of chip and integration of components is becoming more and more extensive. The high-density requirements of electronic products on PCB boards are more prominent. In the future, the demand for high-end PCB products such as multi-layer boards, HDI boards, and IC substrates will increase significantly. Electronic products will continue to develop in the direction of “integration, automation, miniaturization, light weight, and low energy consumption”, which will promote the continuous development of PCB in the direction of high density, high integration, high speed and high frequency, high heat dissipation, light weight, and miniaturization , the demand for multilayer boards, rigid-flex boards, HDI boards, substrate-like boards, packaging substrates and other products will increase day by day. From the perspective of PCB product subdivision structure, in 2021, multilayer boards account for 38.6% of the global PCB subdivision products, packaging substrates account for 17.6%, flexible boards account for 17.5%, and HDI boards account for 14.7%. The proportion of double panel is 11.6%.
