The prototype of PCB comes from the telephone exchange system using the concept of “circuit” in the early 20th century. It is made by cutting metal foil into line conductor and sticking it between two pieces of paraffin paper.
PCB in the true sense was born in the 1930s. It was made by electronic printing. It took insulating board as the base material, cut into a certain size, attached with at least one conductive pattern, and arranged with holes (such as component holes, fastening holes, metallization holes, etc.) to replace the chassis of the previous device electronic components, and realize the interconnection between electronic components, It plays the role of relay transmission, is the support of electronic components, known as the “mother of electronic products”.
History of PCB development in China
In 1956, China began to develop PCB.
In the 1960s, the single panel was produced in batch, the double-sided panel was produced in small batch, and the multi-layer panel was developed.
In the 1970s, due to the limitation of historical conditions at that time, the development of PCB technology was slow, which made the whole production technology lag behind the advanced level of foreign countries.
In the 1980s, the advanced single-sided, double-sided and multi-layer PCB production lines were introduced from abroad, which improved the production technology level of PCB in China
In the 1990s, foreign PCB manufacturers such as Hong Kong, Taiwan and Japan have come to China to set up joint ventures and wholly-owned factories, which makes China’s PCB production and technology advance by leaps and bounds.
In 2002, it became the third largest PCB producer.
In 2003, both PCB output value and import and export value exceeded US $6 billion, surpassing the United States for the first time and becoming the second largest PCB producer in the world. The proportion of PCB output value increased from 8.54% in 2000 to 15.30%, nearly doubled.
In 2006, China has replaced Japan as the world’s largest PCB production base and the most active country in technology development.
In recent years, China’s PCB industry has maintained a rapid growth rate of about 20%, far higher than the growth rate of the global PCB industry. From 2008 to 2016, the output value of China’s PCB industry increased from US $15.037 billion to US $27.123 billion, with a compound annual growth rate of 7.65%, which is far higher than 1.47% of the global compound growth rate. Prismark data shows that in 2019, the global PCB industry output value is about $61.34 billion, of which China’s PCB output value is $32.9 billion, accounting for about 53.7% of the global market.
