Printed circuit board is the most active industry in the contemporary electronic component industry, and its industry growth rate is generally about 3 percentage points higher than that of the electronic component industry. It is expected to maintain rapid growth in 2006. Demand upgrading and industrial transfer are the basic driving forces to promote the development of the industry, and HDI board, flexible board, IC packaging board (BGA, CSP) and other varieties will become the main growth points.

　　In 2003, the output value of printed circuit boards in China was 50.069 billion yuan, a year-on-year increase of 333%. The output value exceeded the United States, which ranked second in the world for the first time. In 2004 and 2005, China's PCB output value still maintained a growth rate of more than 30%, which is estimated to reach 86.9 billion yuan in 2005, far higher than the growth rate of the global industry.

　　Flexible circuit board

　　Flexible circuit board (FPC) is rapidly developing towards miniaturization in electronic equipment represented by smart phones, so it is widely used in many electronic equipment segments. On the one hand, products tend to miniaturization; On the other hand, reliability. It is estimated that by 2016, the global output value of flexible circuit board will reach US $13.2 billion, with a compound annual growth rate of 7.5%. The survey has become one of the fastest-growing sub industries in the electronics industry.

　　From the perspective of development form, China's circuit board industry continues to grow at a high speed, and its import and export have also achieved high-speed growth. With the industrial growth, it is gradually being optimized and improved.
