PCB can be divided into ordinary multilayer boards, backplanes, high-speed multilayer boards, metal substrates, thick copper boards, high-frequency microwave boards, and HDI boards according to different production processes. The packaging substrate is developed on the basis of HDI boards and is used for packaging chips, providing multi-dimensional protection such as reinforcement, support, and heat dissipation.

The global PCB market is showing a cyclical growth trend. The global PCB market has gone through four historical cycles of growth and decline. The first cycle is from 1980 to 1992: the global PCB industry has been on the rise and on the rise, with technology and process levels still in the embryonic stage. From 1980 to 1990, it was an upward period with a CAGR of 2.2%, and from 1990 to 1992, it was a downward period with a CAGR of -7.7%. The second cycle was 1992-2002: 1992-2000 was an upward period, with a CAGR of 9.4%. The market grew rapidly and benefited from the upgrading of desktop computers/home appliances. 2000-2002 was a downward period, with a CAGR of -13.9%. The Internet foam burst affected terminal demand. The third cycle is from 2002 to 2009: during the upward period from 2002 to 2008, the CAGR was 7.6%, and the market growth slowed down, mainly benefiting from the development of laptops and feature phones. During the downward period from 2008 to 2009, the CAGR was -14.7%, mainly affected by the financial crisis, during which the market experienced significant fluctuations.

The fourth cycle is from 2009 to 2016: 2009-2014 is an upward period, with a CAGR of 6.8%. The market has entered a stable development stage, benefiting from the diversified development of smartphones and the rapid increase in production. 2014-2016 is a downward period, with a CAGR of -2.8%, mainly affected by the slowdown in product iteration. New growth cycle: After 2016, benefiting from new demands and applications such as 5G, AI, and the Internet of Things, the PCB market has ushered in a new round of growth.

PCB has a wide range of downstream applications, with rapid growth in communication, servers, and automotive tracks. PCB is widely used in various downstream fields such as communication, computers, consumer electronics, automotive electronics, industrial control, military aviation, and medical devices.
