PCB is bitterly known as the "mother of electronic components", and it is a bridge that carries electronic components and connects circuits. However, in the past two years, the Sino-US trade conflict and the new crown epidemic have had a huge impact on the semiconductor industry. PCB is also unreliable. To avoid being affected to a certain extent.
According to industry insiders, judging from the current terminal market and supply chain feedback, the current demand for PCBs is actually on the rise, including 5G, smart homes, and new energy vehicles. Taking Xinlunyuan automobile as an example, the demand for PCB will be 4-5 times that of traditional automobiles, and the overall market demand is strong.
At the same time, due to the shortage of chips in the market, the progress of many customers' products is not as good as expected, including the assembly of PCB and the production of finished products in the later stage. Lin Chaowen, technical director of Indavino, believes that due to the long-term shortage of chips and price increases, many domestic electronics companies have responded by localizing or replacing chips. Free proofing has enhanced the enthusiasm of many enterprises and college teachers and students for PCB proofing, and has brought a certain degree of growth to the PCB manufacturing market.
Although the demand for PCBs in new energy vehicles has greatly increased, due to the use of large-capacity batteries in new energy vehicles, the current in the circuit becomes larger, and current-carrying design and thermal design become crucial, and reliability is more important for PCBs Design, but from the performance point of view, the point that affects reliability the most is heat generation. Therefore, it is necessary to control the heat from the IC package, through the PCB, and to the complete product in the operating environment.
In addition, the new car is also equipped with technologies such as automatic driving, radar, and smart cockpit. Compared with traditional cars, the PCB design is much more complicated, and to realize these rich functions, the speed requirements of the signals carried by the PCB will be higher. Higher, and there may be a demand for HDI boards on smart cockpits. At the same time, Xinjiao energy vehicles are usually equipped with many camera modules, which requires more flexible and rigid boards.
In addition to new energy vehicles, high-end PCB manufacturing for integrated circuit supporting industries, such as semiconductor testing equipment, will usher in a rapid growth process in the future, and this field was mainly occupied by the United States, Japan, South Korea and other countries in the past.
In the field of display technology, especially the next generation of active LEDs, the backlight module usually has the same size as the screen, and the size of the PCB. And this kind of display equipment is usually used in fields such as monitoring large screens and outdoor advertising screens, and the current market demand is also rising.
In the field of 5G and smartphones, Lin Chaowen said that 5G is mainly reflected in the design considerations of PCB materials and signal transmission quality. Compared with 4G, 5G has higher speed, larger capacity and lower delay. The same "heat" problem brought to 5G base stations and terminals has attracted much attention from the industry. In the field of smartphones, 5G mobile phones are continuously upgraded in the direction of high performance, high screen quality, high integration, and thinness. Compared with the 4G era, the heat generation has increased significantly, and the heat dissipation requirements have also increased significantly. In the circuit design of the 5G field, more energy-saving devices and more effective PCB cooling solutions are urgently needed.
It can be seen that with the current development of new energy vehicles, 5G, new display technology, semiconductor testing and other fields, the demand for PCBs in the domestic market is also rising, and due to the upgrading of technology, higher requirements are also put forward for PCB design. Require.
