Printed circuit board (PCB) is a substrate for assembling electronic parts. It is a printed board that forms the connection between points and printed components on the general substrate according to the predetermined design. According to different classification methods, printed circuit boards can be divided into different types. According to the number of layers, printed circuit boards can be divided into single panel (SSB), double-sided board (DSB) and multilayer board (MLB); According to the flexibility, printed circuit board can be divided into rigid printed circuit board (RPC), flexible (also known as flexible) printed circuit board (FPC) and rigid flexible combined printed circuit board.
In recent years, due to the adjustment of industrial structure in developed regions in Europe and America and the cost advantage in Asia, the global PCB manufacturing has gradually shifted from Europe and America to Asia, especially mainland China. Since the late 1990s, the output value of printed circuit boards in China has developed rapidly, becoming a region with the global PCB output value growing Zui fast.
In 2017, there were more than 1300 PCB enterprises in Chinese Mainland (down from the previous year). The market showed a highly decentralized competition pattern. The enterprises were generally small in scale, and there were no certain leading enterprises. According to the statistics of the report on in-depth market research and investment prospect prediction and analysis of the printed circuit board (PCB) industry in 2018-2023 released by xinsijie Industrial Research Center, China's PCB output value in 2017 was US $26.977 billion, accounting for more than 50% of the global total output value. In 2017, the top ten PCB enterprises in China were Zhending technology, Jianding technology, Zixiang electronics, Xinxing electronics, Weixin electronics, Shennan circuit, Otis, Hushi electronics, Zhichao technology and Jingwang electronics. Among them, Ding Technology Holding Co., Ltd. topped the list with a revenue of 24.244 billion yuan in 2017.
The PCB industry has a consistent large cycle with the global economy. In the past two years, affected by the global economy and computer sales downturn, the prosperity of PCB industry has been at a low level. Since the first half of 2016, the global economy has returned to the boom and upward track, the semiconductor cycle has risen, and there are obvious signs of recovery in the PCB industry. At the same time, the prices of bulk commodities such as copper foil and glass fiber cloth, which are the main costs of the industry, are still falling after a sharp decline in the past year, ushering in a large bargaining space for PCB enterprises. The large-scale investment in domestic 4G has become a catalyst for driving the industry boom beyond expectations.
With large PCB manufacturers all over the world investing and building factories in China, the technical level of domestic PCB is improving day by day, but there is still a gap between high-end PCB production technology and Europe, America and Japan. At present, most of the main raw materials required for PCB production can be produced in China, but some production equipment with high degree of automation, high precision and reliability requirements, such as electroplating production line and laser drilling machine, mainly rely on foreign imports. In the future, the research and development of high-end PCB production technology will become a new development focus for domestic PCB manufacturers.
Xinsijie industry researcher believes that PCB technology is closely related to the technical development trend of mainstream products in the downstream industry. At present, electronic products are updated very fast, with higher and higher technical content and stricter quality requirements. For example, mobile phone consumers hope that mobile phones will be lighter and thinner. Therefore, the technical requirements of downstream customers for PCB products are also gradually improved. PCB manufacturers need to constantly update their manufacturing processes and technologies to meet the increasing technical needs of downstream customers for products.
