PCB originates from its method of manufacture through electronic printing. Starting development in 1956 and expanding between 1963 and 1978, China’s PCB industry grew significantly over two decades of economic reform, spurred by advanced foreign technology and equipment. By 2002, China became the world’s third-largest PCB producer. The industry sustained around 20% growth in recent years, surpassing Japan by 2010 in output value and technological development.
