Brief discussion on the relationship between printed circuit and 5G

The Printed Circuit Board (PCB) industry is the basic industry of electronic information product manufacturing, and it is also the industry with the largest output value in the global electronic component industry. PCB has a wide range of applications and is an indispensable accessory in modern electronic equipment. In electronic equipment, PCB is the "skeleton" for loading components and the "blood vessel" for transmitting current signals, and is the basic product of the electronic information industry. PCB technology spans multiple disciplines such as mechanics, optics, microelectronics, electrical engineering, chemistry, materials, applied physics, etc. As electronic equipment becomes more and more complex, the role of PCB in electronic equipment becomes more and more important. In this extraordinary period of the nation and the world in the fight against the new coronavirus epidemic, PCBs are supporting many medical equipment and have become the priority product after the emergency resumption of work..
