PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board. It is an important component, a support for components, and a carrier for electrical connection of components. Because it is made by printing, it is called a "printed" circuit board.

The role of PCB circuit board

After the equipment uses printed boards, due to the consistency of similar printed boards, manual wiring errors can be avoided, and components can be automatically inserted or mounted, automatic soldering, and automatic detection, which ensures the quality of the equipment and improves Labor productivity, cost reduction, and easy maintenance.

Since the reform and opening up, due to preferential policies in terms of labor resources, market, investment, etc.,

pcb board

China has attracted large-scale transfers of European and American manufacturing industries. A large number of electronic products and manufacturers have set up factories in China, which has led to The development of related industries within. According to China’s CPCA statistics, in 2006, my country’s actual PCB output reached 130 million square meters, and the output value reached 12.1 billion US dollars, accounting for 24.90% of the global PCB output value, surpassing Japan to become the world's number one. From 2000 to 2006, the average annual growth rate of China's PCB market reached 20%, far exceeding the global average. The global financial crisis in 2008 caused a huge impact on the PCB industry, but did not cause a catastrophic blow to China’s PCB industry. Under the stimulation of national economic policies, China’s PCB industry recovered in 2010. In 2010, China’s PCB output value reached 19.971 billion US dollars. . Prismark predicts that China will maintain a compound annual growth rate of 8.10% from 2010 to 2015, which is higher than the global average growth rate of 5.40%.

 Uneven regional distribution

China's PCB industry is mainly distributed in South China and East China, and the two together reach 90% of the country's total. The effect of industrial agglomeration is obvious. This phenomenon is mainly related to the fact that the main production bases of China's electronics industry are concentrated in the Pearl River Delta and the Yangtze River Delta.

PCB downstream application distribution

Distribution of downstream applications in China's PCB industry. Consumer electronics accounted for the highest proportion, reaching 39%; followed by computers, accounting for 22%; communications accounting for 14%; industrial control/medical equipment accounting for 14%; automotive electronics accounting for 6%; defense and aerospace aviation accounting for 5%.

Backward technology

Although China is now the world's largest in terms of industrial scale, it still lags behind the world's advanced level in terms of the overall technological level of the PCB industry. In terms of product structure, multi-layer boards account for most of the output value, but most of them are low-end products with less than 8 layers. HDI, flexible boards, etc. have a certain scale, but in terms of technical content, they exist with advanced foreign products such as Japan. The gap, the IC carrier board with the highest technical content is rarely produced by domestic companies.
