Printed circuit board (PCB) is the substrate used for assembling electronic parts. It is the printed circuit board that connects and prints components between points according to the predetermined design on the general substrate.Printed circuit boards can be divided into different types according to different classification methods.According to the number of layers, PCB can be divided into single panel (SSB), double panel (DSB) and multilayer board (MLB).According to the softness, 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 the United States and the cost advantage in Asia, the global PCB manufacturing has gradually shifted from Europe and the United States to Asia, especially the mainland of China.Since the late 1990s, the output value of printed circuit board in China has developed rapidly and become the fastest growing region in the world.
In 2017, there were more than 1300 PCB enterprises in mainland China (down from the previous year), and the market showed a highly decentralized competition pattern. The scale of enterprises was generally small, and there was no absolute leading enterprise.According to the statistics of "2018-2023 printed circuit board (PCB) industry market in-depth research and investment prospects forecast and analysis report" published by xinsijie industrial research center, the output value of PCB in China in 2017 was 26.977 billion us dollars, accounting for more than 50% of the global output value.The top ten PCB enterprises in China in 2017 are zhending technology, jianding technology, zixiang electronics, xinxing electronics, weixin electronics, shennan circuit, aotes, hushi electronics, zhichao technology and jingwang electronics.Among them, ding technology holding co., ltd. topped the list with revenue of 24.244 billion yuan in 2017.
PCB industry and global economy have the same big cycle.In the past two years, the industry has been suffering from the global economy and computer sales downturn, PCB industry prosperity has been at a low level.Since the first half of 2016, the global economy has returned to the upward track of prosperity, the semiconductor cycle has gone up, and the PCB industry has shown obvious signs of recovery.At the same time, copper foil and glass fiber cloth, as the major costs of the industry, have experienced a sharp decline in the past year, but their prices are still falling, which provides PCB enterprises with more bargaining space.And the large-scale investment of 4G in China has become the catalyst that drives the boom of the industry to exceed expectations.
As large PCB manufacturers from all over the world invest and build factories in China, the technical level of PCB in China is improving day by day. However, the production technology of high-end PCB still lags behind that of Europe, America and Japan.At present, most of the main raw materials needed for PCB production can be produced in China, but some production equipment with high automation, 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 the new development focus of domestic PCB manufacturers.
According to the researcher of xinsijie industry, PCB technology is closely related to the technological development trend of mainstream products in the downstream industry. At present, the update speed of electronic products is very fast, with increasingly high technical content and more stringent quality requirements. For example, mobile phone consumers want thinner and thinner phones.Therefore, the technical requirements of downstream customers on PCB products are also gradually improved.PCB manufacturers need to constantly update the manufacturing process and manufacturing technology to meet the downstream customers' increasing technical requirements for products.
