Printed circuit boards were created by Austrian Paul Eisler, who first introduced printed circuit boards to radios in 1936.In 1943, americans began using the technology in military radios, and in 1948, the United States officially approved the invention for commercial use.Since the mid-1950s, printed circuit boards have been widely used.
Before the advent of PCB, the interconnection between electronic components was completed by relying on direct wiring.Today, wires exist only for laboratory applications.Printed circuit board in the electronic industry has certainly occupied the position of absolute control.
PCB manufacturing technology for the future development trend 沁continent and abroad discussing basic is consistent, namely to high density, high precision, small aperture, thin wire, small spacing, high reliability, multiple stratification, high-speed transmission, light weight, thin, on the production at the same time to improve productivity, reduce costs, reduce pollution, to adapt to many varieties, small batch production.The technological development level of printed circuit is generally represented by the line width, aperture, plate thickness/aperture ratio on the printed circuit board.
Since the reform and opening up, China's preferential policies in labor resources, market, investment and other aspects have attracted large-scale transfer of European and American manufacturing industry. A large number of electronic products and manufacturers have set up factories in China, which has driven the development of relevant industries including PCB.According to CPCA statistics of China, in 2006, China's actual PCB production 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 first. From 2000 to 2006, the annual growth rate of PCB market in China 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 the PCB industry in China. Under the stimulus of national economic policies, the PCB industry in China experienced a full recovery in 2010, and the output value of the PCB in China reached 19.971 billion US dollars in 2010. From 2010 to 2016, China maintained a compound annual growth rate of 8.10%, higher than the global average of 5.40%.
