Printed circuit board (PCB) is a substrate for assembling electronic parts. It is a printed board that connects and prints components on common substrate according to the predetermined design.According to different classification methods, printed circuit boards can be divided into different types.The printed circuit board can be divided into single panel (SSB), double panel (DSB) and multi-layer board (MLB) according to the number of layers.By 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 printed circuit board.
In recent years, due to the adjustment of industrial structure in developed regions of Europe and America as well as the cost advantage in Asia, global PCB manufacturing has gradually shifted from Europe and America to Asia, especially in mainland China.Since the end of 1990s, the output value of printed circuit boards in China has developed rapidly and become the fastest growing region in the world.
In 2017, there were more than 1,300 PCB enterprises in mainland China (down from the previous year), and the market presented a highly decentralized competitive pattern. The enterprise scale was generally small, and there were no absolute leading enterprises.According to the "2018-2023 in-depth market research and investment prospect forecast analysis report of PCB industry" released by xinsi industry research center, China's PCB output value in 2017 was usd 26.977 billion, accounting for more than 50% of the global output value.The top 10 PCB enterprises in China in 2017 are zhending technology, jianding technology, zixiang electronics, xinxing electronics, weixin electronics, shennan circuit, aotz, hushi electronics, zhichao technology and jingwang electronics.Among them, ding technology holdings co., which topped the list with 24,244 million yuan in revenue in 2017.
PCB industry and the global economy have a consistent big cycle.The industry has been depressed over the past two years as the global economy and computer sales have slowed.Since the first half of 2016, global economy has returned to the upward trend, semiconductor cycle upward, PCB industry recovery signs are obvious.At the same time, the bulk commodity copper foil, glass fiber cloth, which is the main cost of the industry, is still falling after a sharp decline in the past year, which gives PCB enterprises greater bargaining space.And the large-scale investment of 4G in China has become a catalyst to drive the industry boom beyond expectations.
With the investment and establishment of large-scale PCB manufacturers in China, the technical level of domestic PCB is improving day by day, but the production technology of high-end PCB still lags behind that of Europe, America and Japan.At present, most of the major 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 has become a new development focus for domestic PCB manufacturers.
According to xinsi industry researcher, PCB technology is closely related to the technological development trend of mainstream products in the downstream industry. However, at present, electronic products are updated at a very fast speed, with higher technical content and stricter quality requirements.Therefore, the technical requirements of downstream customers for PCB products are gradually improved.PCB manufacturers need to continuously update manufacturing processes and technologies to meet the constantly improving technical requirements of downstream customers.
