Flexible circuit board industry will enter an explosive period

Folding mobile phones have been regarded as an industry direction. This year, with Huawei, Huawei, Samsung, Rouyu and other manufacturers having officially released folding screen mobile phones, Xiaomi, OPPO, vivo and other manufacturers have also produced relevant prototypes of folding screen mobile phones. Folding mobile phone has been opened in the first year. Among them, the flexible circuit board has become an indispensable component of folding mobile phones because of its light weight, thin thickness, good flexibility and other characteristics. However, FPC (flexible circuit board) application in smart phones is still facing many technical difficulties, which will become the focus of current manufacturers to overcome.

FPC has the characteristics of thin, flexible, winding, foldable, and high wiring density, which perfectly fits the development theme of thin, light, and miniaturization. In recent years, FPC has become the leader of PCB (printed circuit board) subdivision industry. FPC is mainly used in mobile terminals, consumer electronics, automotive electronics, industrial control, medical, aerospace and military. Among them, mobile terminals are the largest application field of FPC, especially smart phones. They are also the field with the highest requirements for FPC’s technical capabilities, and will lead the technical development direction of FPC in the future. The development trend of miniaturization and intelligence will make flexible mobile phones become a trend in the future.

Experts also put forward solutions to the requirements of folding, linking and multiple use of folding screen for fpc. In flexible screen mobile phones, due to the need to fold and use many times, the requirements for the flexible circuit board inside the mobile phone will be higher, and the corresponding use area will be further increased. However, FPC is usually manufactured by batch process, so it is limited by the size of production equipment. In view of this problem, experts believe that it can be extended through the middle socket, and FPC can be reinforced by plugging gold finger.

The increase of FPC applications in mobile phones will become an established trend, which also makes the FPC market a positive trend. However, FPC still faces manufacturing problems, such as large-scale applications in folding screen mobile phones. Of course, there are corresponding solutions to these problems, but these solutions will inevitably lead to cost increases. How to better control FPC costs can only be solved by mass production or technical upgrading.
