The printed circuit board (PCB) plays a supporting  in an electronic device, the interconnection part of the role of the circuit element. Integrated circuits, resistors, capacitors and other electronic components only have gained a foothold on the printed circuit board and wire communication in order to perform its functions in the overall. Therefore, PCB is known as "the mother of electronic products," said. With the continuous development and deepening of the electronic information industry, PCB has a wide range of applications. in the field of consumer electronics, computers, communications equipment, China PCB industry downstream applications, consumer electronics accounted for 39%; followed by computing, accounting for 22%; communication accounted for 14%; industrial control / medical equipment accounted for 14%; automotive electronics accounted for 6%; defense and aerospace accounted for 5% . The CBIW studies have shown that China's auto production in 2012 was 19,272,000, 19,306,000 of sales, smartphone and PC to shipments of more than 500 million. The huge market demand-driven printed circuit board industry into the fast lane. Printed circuit board manufacturing industry chain upstream and downstream industries are closely linked. Industry chain upstream, CCL, copper foil, glass fiber yarn / fabric needs; downstream industry chain, closely related to the normal operation of the function module with all kinds of electronic products. Business intelligence network released the "2013-2018 China printed circuit board industry market prospects research and investment and financing strategy consulting report pointed out. Taiwan, China printed circuit board manufacturing more than 130 enterprises, more than 1,200 mainland. Mainland China, there are more than 800 special materials, special equipment of enterprises, more than 500 companies and more than 1,000 agents, more intense competition in the industry. In 2012, China printed circuit board manufacturing industry realized a sales income of 311.7 billion yuan. The state has introduced the electronic information industry "Twelfth Five-Year" development plan "," Twelve Five "period to accelerate the development of high-density interconnect board, special printed circuit board, a light-emitting diode (LED) with a printed circuit board and other key The core of the device. "Twelve Five" period, China's PCB industry towards the prosperity of an important opportunity, seize the new round of development opportunities in the global electronic information industry, around the entire core of the industrial structure, vigorously promote independent innovation to achieve smooth printed circuit industry in China sustainable development and transformation. To "Twelve Five" period, China printed circuit industry is not only the scale of the industry will remain the world, and the level of industrial technology and R & D capabilities will also be among the world's advanced ranks. With the quickening pace of recovery in the downstream industry, the printed circuit board industry is facing broad market prospects.
