History of PCB Development in the World and China

2019 MARKs the 70th anniversary of the founding of New China. Overcoming obstacles in 70 years, 70 years of ups and downs. Over the past 70 years, under the correct leadership of the CPC, New China has made remarkable achievements. In the field of science and technology, generations of scientific and technological workers have worked hard. China's scientific and technological strength and economic development have grown at the same time, achieving a historic leap from hard to follow, parallel, and even leading. As the "mother of electronic products", PCB is one of the outstanding representatives in the field of electronic technology.

On the occasion of the 70th anniversary of the founding of New China, Maxwell Technology will take you today to review the development history of China's PCB.

World PCB History

In 1936, Austrian Paul Eisler, the creator of PCB, first used PCB in radio equipment.

In 1943, Americans mainly used this technology in military radio.

In 1947, the US Aviation Administration and the US Bureau of Standards launched the first PCB technology sEMInar.

circuit board

In 1948, the United States officially recognized the invention and used it for commercial purposes.

In the early 1950s, with the solution of the problems of the adhesive strength and welding resistance of CCL copper foil and laminated materials, the performance was stable and reliable, and large-scale industrial production was realized. Copper foil etching has become the mainstream of PCB manufacturing technology and started to produce single panel.

In the 1960s, large-scale production of double-sided PCB with hole metallization was realized.

In the 1970s, multilayer PCB developed rapidly and continued to develop towards high-precision, high-density, thin wire and SMAll hole, high reliability, low cost and automatic continuous production.

In the 1980s, SMT gradually replaced plug-in PCB and beCAMe the mainstream of production.

Since 1990s, surface mount has developed from flat package (QFP) to ball grid array package (BGA).

Since the beginning of the 21st century, high-density BGA, chip level packaging and multi chip module packaging printed circuit boards based on organic laminates have developed rapidly.

History of PCB development in China

In 1956, China began the research and development of PCB.

In the 1960s, single panel mass production, double-sided panel small batch production and multi-layer panel development.

In the 1970s, due to the limitation of historical conditions at that time, the development of PCB technology was slow, which made the entire production technology lag behind the advanced foreign level.

In the 1980s, advanced production lines for single-sided, double-sided and multi-layer printed boards were introduced from abroad, which improved the production technology level of printed boards in China

In the 1990s, Hong Kong, Taiwan, Japan and other foreign PCB manufacturers came to China to establish joint ventures and wholly owned factories, which made China's PCB production and technology advance by leaps and bounds.

In 2002, it became the third largest PCB manufacturer.

In 2003, PCB output value and import and export volume 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 output value has almost doubLED from 8.54% in 2000 to 15.30%.

In 2006, China replaced Japan as the world's largest PCB production base and the country with the most active technological development.

In recent years, China's PCB industry has maintained a high growth rate of about 20%, which is far higher than the growth rate of the global PCB industry.

Current situation of China's PCB industry

Under the general trend of the global PCB industry transferring to Asia, China, as a major electronics manufacturing country, has attracted a large number of foreign investment and local PCB companies with its huge domestic demand market and relatively low production costs, which has promoted the rise of China's PCB industry in just a few years. Explosive growth.

At present, China has become the world's largest PCB manufacturer and one of the world's largest PCB manufacturers
