At present, there are approximately 1500 PCB enterprises in China, forming a pattern of joint competition among Taiwanese, Hong Kong, American, Japanese, and domestic enterprises. Among them, foreign-funded enterprises generally have a large investment scale, and have certain advantages in production technology and product specialization; There are many domestic enterprises, but there is still a certain gap in their scale and technological level compared to foreign enterprises.

　　Among them, China's printed circuit industry is mainly distributed in the southeast coastal areas, which is also related to the large demand for water in the PCB industry. These areas are relatively rich in water resources. The Yangtze River Delta and the the Pearl River Delta add up to 90% of the national total. The PCB industry investment analysis indicates that the ratio of the Yangtze River Delta to the Pearl River Delta is about 1:1 at present.

　　The proportion of boards (single panel, double-sided board, multi-layer board, HDI board) in China reaches 83.8%, with multi-layer boards accounting for the largest proportion with a proportion of over 50%, followed by soft boards with a proportion of 15.6%. Due to the pressure of oversupply, most manufacturers have entered a price war, resulting in lower than expected output growth. With the continuous expansion of production capacity by large factories, the output value of HDI boards increased significantly by as much as 40% in 2018, accounting for 13.6%. The mainstream single and double sided boards in the past have been decreasing year by year.

　　In the next five years, driven by the domestic electronic information industry, the printed circuit board market in China will continue to grow at a growth rate higher than the global level. It is expected that by 2022, the scale of China's PCB market will reach 35.69 billion US dollars. However, the Pearl River Delta remains the most important and largest PCB industry research and development production base in China, with a concentration of about 60% of the country's enterprises and PCB production capacity. The above is all the content of investment analysis in the PCB industry.
