PCB board as a substrate for electronic products plays a decisive role, with the continuous improvement of China's economy, the rapid development of electronic products, which also directly promote the development of China's circuit board industry. Therefore, China has already become a major producer of PCB circuit boards. However, in the technical field, we still have a large gap with countries and regions such as Europe, America and Japan.

   With the increasing emphasis on technology in recent years, China's printed circuit board technology is also steadily improving. As the largest supplier of iPhone cell-phone substrates, the state-owned veteran circuit board factory, Shennan Circuit, showed us the latest PCB board and substrate products at the 2013 Shenzhen Integrated Circuit Exhibition.

   Current electronic products are developing in a thin and smart manner. The PCB industry naturally has to keep up with the trend. This will require its substrates to become thinner and lighter, but it is still a challenge for domestic circuit board manufacturers. How to use a thinner dielectric layer to process products, and mass production, to control higher yields, this is the future competitiveness of the company. Currently there are few domestic substrate manufacturers, and SN circuit targets can now be mass-produced to 40um substrates, which is a leading position in the industry. Meizhou Hongzhan Electronic Technology Co., Ltd. is also attacking this area.

   In the PCB source materials and other aspects are basically controlled in Europe and the United States, Japan, South Korea and other countries (such as the substrate of the PCB soft board), which also makes China's PCB circuit board development controlled by the people, currently also set up some major domestic projects, hope in the near In the future, our technology can catch up with the world's advanced water.
